MVP Waterfall vs. Agile Method

Decoding the difference between the waterfall and agile methods in mvp development

Which is better the MVP Waterfall or Agile method? You may have heard these words come up in conversation if you are considering getting your MVP developed. Building the product which you have interpreted to your app development team is critical. Knowing how it will be executed really matters to have a successful MVP. 

So let’s dive in, before agile development was adopted most software products were actually developed using what is called the “Waterfall approach” Waterfall is also referred to as a “big design up front” (BDUF) approach. A key aspect of using the MVP Waterfall approach in mobile app development is that the team does not progress until the previous step is 100% complete. Meaning, no design happens until all of the requirements are defined, and no coding happens until the entire product is designed. (Olsen, 2015) 

Essentially it proceeds sequentially through a series of steps, gathering and analysis, system design, development, integration and testing, deployment, and maintenance, in that order.

Waterfall Model

Conversely with the now popular Agile methodology, the product is broken down into smaller pieces that undergo shorter cycles of requirements definition, design, and coding. Unlike with the Waterfall method, the developers can begin to code before the design elements have been completed. Instead of following a rigid plan, Agile focuses on flexibility and promotes quick responses to change. 

Which MVP Method Is Better Agile Or Waterfall?

The answer to that question depends on the type of MVP. Typically the Waterfall method is good for larger projects or smaller projects that are very defined. Agile methods are great to get deliverables out to customers much faster. With the agile method there is also constant dialogue between the MVP development team and the customer. Yet this does not mean that the Waterfall method is not the way to go to complete the project. Depending on the type of project, this type of attention to detail and refinement is needed to create a minimum viable product which has the least amount of error known and unknown as possible. 

For example think about the mini-van, who could fathom sending a family down the highway in a not nearly completed mini-van MVP? Checking and rechecking the design and requirements with this kind of scope can make the MVP Waterfall method the best way to handle certain projects. However what is fantastic about the Agile process is in every stage the customer is front of mind. At the end of any Agile project, what you have is a working product that the customer can use. 

Breaking Down MVP Waterfall vs. Agile Methods Key Benefits

Benefits of using the Agile MVP Method:

  • The agile method is based on breaking down the project into smaller increments, the development team can react to changes in the market or other new information more quickly.
  • Your product reaches the customer earlier, meaning you can begin to start receiving customer feedback sooner. Which will assist with guiding subsequent product development efforts. 
  • A team can also reduce the margin of error if they are working on the project in smaller increments, allowing them to see issues as they arise much sooner than they would if they waited. 
  • The agile method encourages a mindset to software development focused on creating value for customers.

Benefits of using the Waterfall MVP Method:

  • Perfect for customers who know exactly what they want.
  • The waterfall process model is very simple to understand and use
  • Phases are processed and completed one at a time
  • Well understood milestones
  • The waterfall Model illustrates the software development process in a linear sequential flow. This means that any phase in the development process begins only if the previous phase is complete. In this waterfall model, the phases do not overlap. (source: sdlc, waterfall model)

Quick Note About The MVP Waterfall Method 

With the MVP Waterfall method it is important to note that once the project is underway and in the testing phase, it is very difficult to go back and change something that was not well thought out or well documented in the conception stage of the project. If you are going to choose the Waterfall method for the development of your MVP it is important that you remember to communicate any changes or new developments before going into the testing environment. 

For an entrepreneur or business owner who has a pre-determined set of requirements, knows exactly what they want from the mobile app they plan to have developed, the Waterfall method may in fact be the best way to go. The Waterfall method is also very useful with enterprise projects.

Backend design

/0 Comments/in , , /by

When I was younger – as in less-than-a-decade old – I wanted to be an architect. That was, until I learned about the existence of trigonometry, calculus, and all the higher-than-geometry level math I could never possibly hope to understand. I liked drawing houses and castles, not mathematically planning them.

Many professions, just like that of architect, necessitate the mastery of hidden skillsets or knowledge bases that the layperson isn’t aware of; the perfect example of this being backend developers. The title, and the topic that comes with it, is enough to make most people instantly glaze over – even some frontend developers will look for an excuse to escape from the conversation.

There’s a reason that this blog is titled “backend design,” however – a lot more design goes into backend development than you would think. Or, more accurately stated, a lot of design goes into architecting the backend.

Systems architecture

According to Introduction to Systems Architecture Design by Medium, backend architecture is “… a conceptual representation of the components and subcomponents that reflects the behavior of the system.”

In other words, backend design is architecting a structure for the frontend, user-facing data layer. It’s akin to designing a car – there’s just as much artistry necessary as engineering. Code is code is code – there’s nothing special about Ruby on Rails or Node.js. Once mastered, the language of the backend can be written just as fast as a frontend developer working in Swift or JavaScript.

Just as a good UI designer knows how to create a rectangle in Sketch, so to does a backend developer know how to build a NoSQL database: the true skill of design is knowing where to place that rectangle in order to create a pleasing layout, or how to organize data in order to minimize latency.

So know that when someone starts talking about systems architecture, they’re really talking about architecture, and less about code. And once this topic is broken down, it’s not that complicated (on a high-level, at least) to comprehend.

The backend can be broken down into three layers:

  1. Controllers – these handle client requests, such as when a user adds an item to their cart.
  2. Services – access data in the DAO layer, and send it back to the controller, which then sends the retrieved information to the client.
  3. Data Access Objects (DAO) – This is the layer where data can be stored, organized, and accessed.

Most often, these layers can be implemented by cloud providers; these platforms – like Amazon Web Services, Google Cloud Platform, or Microsoft Azure – will sell managed services like on-demand servers, or databases (in addition to many other services).

When someone speaks to the scalability of the cloud, this is what they’re referring to; “the cloud” is really a collection of remote servers that provide customers with ready-made backend infrastructure, giving companies the ability to increase their operations without needing to store, manage, and maintain servers physically on site.

Within these layers are components, of which we’ll cover the four most basic and widely-used:

  1. Virtual machines – Like most things in the world of computers, the moniker “virtual machine” is an apt descriptor of what VMs do; a VM is nothing but a computer simulated inside of a computer, much like a digital Russian nesting doll. When utilizing cloud providers, VMs will be hosted on larger servers that allocate the necessary CPU, RAM, SSD, and network bandwidth in order to run your VM – this exact process can be achieved on a personal computer as well. VMs run the operations of your backend.
  2. Load balancers – Run too many applications on your computer, and it’ll start to slow down. The same is true for your VMs in the cloud or on your local servers – too many client requests, and the time it takes to load a page can skyrocket. Your backend’s load balancer is designed to solve this problem: load balancers act as a medium between your backend’s controllers and services layer. Load balancers both interpret client requests from the controllers layer, and keep track of the health of VMs – and to ensure low latency client request, the load balancer distributes those client requests evenly between VMs.
  3. Databases – Databases are how your DAO layer is organized. There are two types of database structures: non relational (NoSQL), or relational (SQL). We’ll cover those a little bit below.
  4. Caches – The reason databases can have different structures is because certain databases are optimized for different types of data, in order to decrease the time it takes to access information. Caches are used for the same reason; during times of heavy traffic, caches can store data that is sure to be accessed in rapid succession by many clients, thus reducing the time it takes to complete client requests. Caches can be thought of as super-optimized, small databases.

Back it up

Before we get into anything more complicated, theres a few basic concepts we can go over now that we’ve covered the building blocks of the backend:

  1. Latency – This is the length of time it takes a client request to complete. Latency always refers to time.
  2. Bandwidth – This is the maximum amount of client requests (data) your server can handle.
  3. Throughput – This is the true amount of data your servers can handle. Often, during times of high traffic, bandwidth will drop as latency rises – this new measurement is called throughput.

In order to reduce latency and increase bandwidth, backend systems will be scaled up to process more client requests. This can be achieved via three different methods:

  1. Vertical scaling – This method reduces latency by increasing the amount of requests a single VM or physical server can handle by upgrading the CPU, RAM, or SSD of the machine.
  2. Horizontal scaling – Reduces latency by adding more VMs or physical servers, thereby increasing the number of client requests that can be handled at a given moment.
  3. Auto scaling – uses the same principle as horizontal scaling, but automates the process: VMs are added as they are needed, and deleted as client requests decrease. Both auto and horizontal scaling necessitate a load balancer.

Another design choice that can reduce latency is the type of database your DAO layer makes use of. As stated above, there are two types of database structures: SQL and NoSQL. While SQL databases are organized to write data in a very efficient manner; NoSQL databases are organized to read data quickly, but due to their structure, require duplicate data in order to access information.

You can think of a SQL database as a collection of tables that hold very specific, uniform sets of information, that link up in a web. NoSQL databases are structured in branches, which lead to other branches, which lead to other branches.

SQL - NoSQL

Both come with their pros and cons – NoSQL databases can access information faster, and are optimized for dealing with un-related sets of data. SQL databases are robust and optimized for dealing with requests that require relational data from various processes in your backend’s service layer.

Back in business

Just as a house would fall apart without the wooden structure, plumbing, wiring, and ventilation, so to would your website or application without its backend. It’s important to know what’s going on back there!

Stay tuned for our future look into scaling up your backend systems.

Why MVP for your mobile app?

/0 Comments/in , , /by

Why do so many software products start out as MVPs?

The reason is due to the significant benefits MVP software brings to the development process: faster, more affordable development, and reliable, resourceful market validation. Essentially, a MVP is a quick method of validating your product via customer feedback. But before we get any further, let’s go over what “MVP” actually means.

MVP stands for:

Minimum – the minimum set of features a product can have while still remaining…

Viable – to provide value to customers, so they are willing to engage with the…

Product – which is ready to be used for consumption.

The development of technological products has always lent itself to that of a MVP – from Alexander Graham Bell’s telephone to the 1998 startup named Google, MVPs have had a huge impact on the way users and products co-exist and co-benefit from each other.

Well-known MVPs

It wouldn’t be fair to say that the following products should still be considered MVPs presently – but rather that they started out that way, and over many iterations, have become the products, services, and platforms they are now.

Facebook

Back when this social media giant was known as The Facebook in 2004, the product offered was most definitely a MVP. During its 1.0 phase, Facebook was a website available only to Harvard students – the intention behind this limited release was to collect feedback in order to create a more robust and user-friendly product. At this time, Facebook was nowhere near what it is today – the website comprised of a profile page, friend requests, and a “send message” feature.

AirBnB

The story of this internationally-used app is the perfect example of a successful MVP product. An idea thought up in 2007 when roommates Brian Chesky and Joe Gebbia were unable to afford rent in the expensive real estate market of San Francisco, the app now known as Airbnb was originally a website by the name of airbedandbreakfast.com.

The site’s first listing (Chesky and Gebbia’s apartment living room) was a true MVP experience as well: an air mattress in a room, along with a cooked breakfast. These are the amenities users of the original site were offered. After the addition of Nathan Blecharczyk (the creator of the website) and the Industrial Design Conference of 2008 held in San Francisco created a need for extra lodging in the area, the company was able to host its first guest.

Now, the company is considering the possibility of opening its own airline. This is the power of MVP products; they can start out as a single air mattress in your apartment’s living room, and develop into international companies with revenues measured by billions of dollars.

There are many more MVP success stories, like that of Goupon, Amazon, Buffer, Snapchat, and others – but for now, let’s get into what makes a product a true MVP.

MVP theory

As previously stated above, a MVP is a product that provides users with the minimum set of features required to provide a marketable and consumable experience. When Bell invented the telephone in 1876, his product provided a usable method of long-distance communication, and not much else. His original telephone model required users to speak into a standing receiver, and hold another speaker to their ear – and after decades of feedback from customers, phones morphed from rotary, to corded and cordless, and eventually to cell and smartphones.

It is this evolution that is the hallmark of a MVP.

While MVPs do come with quicker development cycles (making it easier to beat competition to market, as well as capitalizing on untapped markets), the most beneficial aspect of a MVP is the direct customer validation.

The market (and your users) will very quickly determine if your product is viable. If the idea is interesting enough, or the solution to the pain point is useful enough, users will jump on board. Therefore, by the usage of a MVP, you can quickly and cheaply prove your validity on the market without wasting time and resources on preliminary marketing and focus groups.

The next step is the most important – listening and reacting to customer feedback. The idea behind a MVP isn’t to build a product with the minimal feature set and then leave it alone – AirBnb didn’t stop at a single air mattress, after all – it’s to create the foundation for a fully-fledged product, platform, or experience.

Take the feedback you receive from early adopters, and implement it – this creates a strong brand for two very important and distinct reasons: your company proves to customers that their voices are heard and matter, and customer-requested features ensure a UX that has been tested against multiple scenarios, environments, and use cases (and lacks any excess features your users don’t want).

MVPs prove your worth

With market validation comes revenue – which can then be used to present a case for your business to investors. After AirBnB’s debut in 2008, the company received their first round of seed money in 2009 from Y Combinator, and by 2010, had raised over $7 million. By 2014, the company was valued at $10 billion, and now, in 2019, boasts a valuation of $35 billion.

MVPs naturally lend themselves to the continual update cycles apps (and all software) are beholden to, and create an environment for meaningful, impactful improvements to your users’ experience. MVPs are more than just a quick way to develop an app – they provide you with the foundation to create a community based around your brand.

The language of app design

/0 Comments/in , /by

What message is your app’s design communicating to your users? Visual design (and UI design in this case specifically) has a language unto itself, and like it or not, your app’s users are reading between the lines.

Visual design is based upon universal principles easily understood by everyone. For example, below, you’ll see two arrows – one pointing left, and one pointing right (or starboard and port, if that floats your boat):

Now, which one is pointing forwards, and which one is pointing backwards?

Or, if we were to flip this idea on its side; based on the two arrows below, which is pointing north, and which is pointing south?

Almost instinctually, your brain knew the answers. You might have even made those visual associations before the questions were posed. These associations come from the language of visual design – taking a left turn in a car doesn’t necessarily mean you’re going backwards, just as walking up a staircase doesn’t mean you’re headed in a northernly direction – our brains only associate an arrow pointing left with the meaning of “backwards” in certain contexts.

This is why you don’t need to be a professional UI/UX designer to understand when an app “feels” wrong – our brains are trained to take in visual information in certain patterns, using standard hierarchies.

Take, for example, what happens when the same left arrow is placed next to the universal sign for “bathroom.”

All of a sudden, there’s no way this arrow means “backwards.” Visual design is precise, and the patterns our brains are trained to recognize mean something. If the design of your app isn’t getting the message across to your users, you’re severely shortchanging yourself, and your app’s chance at success.

Platform design principles

Just because there’s a universal language of design doesn’t mean everything looks the same (thank goodness). Both Apple and Google have their own design principles and schools of thought – those being the Human Interface Guidelines, and Material Design, respectively.

While these OS specific UI design guidelines do cover the more detailed aspects of design, such as typefaces and font use cases (those being San Francisco for iOS, and Roboto for Android), they mainly cover high-level design choices like those of hierarchy of information, menu placement and organization, and text alignment.

This is the reason it’s important to remain cognizant of which platform you are designing for, and why it’s bad practice to simply copy and past the design of an app when developing for both Android and iOS.

For example, iOS users will be familiar with the top menu on the left, and Android users will similarly find the top menu on the right to be familiar:

(Image from this blog by Cory McArthur)

If we were to simplify these design to their wireframe layouts, they would appear as such:

While both present network information, time, and battery usage at the top of this menu, they are located in different positions – both are easily understood, but use different design styles – iOS being making use of center-justified design, and Android left/right justification.

These design styles are made with the intention of being easy to understand – and while they both are, users come to learn and prefer the feel of either Human Interface or Material Design as they interact with either iOS or Android.

Design and user retention

There’s the old adage, “don’t judge a book by its cover.” A saying such as this rings true because the cover doesn’t actually detract from the user’s experience while engaging with the book – the cover is the least-looked-at part of a book while being used.

The direct opposite is true of apps – a poorly-designed app will provide a subpar user experience. An app that suffers from poor design will be difficult to comprehend; and as such, the book’s equivalent of bad UX would be a novel printed with yellow ink on white pages.

According to this blog from Medium, a study conducted in Canada found that a poorly-designed platform actually makes accomplishing the task it was designed to complete more difficult than when compared to a well-designed platform.

It largely comes down to user psychology – a more pleasant experience puts the user into a better mood, which creates a more engaging experience for the user, which means they pay more attention to the app’s flow, which then improves their knowledge retention, which leads them to feel familiar with the app.

Before long, positive feelings are associated with the app – while this is largely dependent on the solution to the pain point the app provides, the experience of arriving at that solution can either be enhanced or tarnished by the UI of an app.

According to this user retention guide from CleverTap, the most important goal of user retention is to “create an immediate, immersive encounter with the app’s unique value.”

In order to do that, you’ll need to create a well-designed UI, so users feel drawn into the experience of your app. No one wants to look at an ugly app for long.

An overview of UI design

UI can be broken down into a few categories when it comes to the interactive design elements UI is created from: navigation, menus, and buttons. Graphics, despite adding significant value to an app’s UI, aren’t truly part of the interactive aspect of an app, other than symbols or icons that may be selected in a menu, such as a “home” button or “shopping cart” button.

Navigation

  • Gestures: Gestures such as swiping or pinching provide tactile methods for users to navigate through, or engage with apps.
  • Screen transitions: Either modal (coming in from the bottom), or push (coming in from the side), screen transitions can simplicity explain if a user has moved on to the next step (push), or entered a sub-step (modal).

Menus

  • Bottom navigation bar: Mainly found in iOS app design, the bottom navigation bar provides an area that showcases all of the app’s navigation options to a user; for example, home, order, review, profile, and much more. Each icon will lead to a different screen, which can then be engaged with to progress through the flow of the app.
  • Hamburger menu: Mainly found in Android apps, the hamburger menu is named as such because it is denoted by a button with three horizontal lines stacked vertically over one another, creating a “hamburger.” This menu will usually expand from the button after being pressed, and is often a push transition.
  • Alerts: Alerts function as small menus, and will often “pop up” when the user has input an action the app must verify. For example, if a user were to clear their cart before completing an order, an alert would pop up, asking if the user indeed intended to clear out their cart, with the option of either pressing “yes” or “no.”

Buttons

There are many types of buttons, but as their name implies, they all require the user the press them in order to function. Some common buttons found throughout app design are: share, add, switches, pickers, and checkboxes.

Custom inventory solutions for the enterprise level business

/0 Comments/in , , /by

There are many inventory management solutions out there, but many are ill-suited to the reality of enterprise level environments that currently exist on legacy systems, or lack the ability to integrate with entrenched ITSM using languages like .NET.

For these reasons, and more (which we will cover below), a third party proprietary inventory management software system won’t make the cut when stacked up against the vast scale and needs of the enterprise level.

The scope of inventory management

Inventory management software can either be used as a standalone system, or integrated within your ERP. A basic inventory management system would provide tools used for:

  • Tracking products
  • Alerting when product levels are low
  • Barcode scanning
  • Generating accurate accounting and financial data

There are many free inventory management software platforms that will offer most of the features listed above, but few include barcode scanning, and many lack reports that can integrate into a larger ERP system – and all are limited to a set number of transactions – such as 100 products in total, or 20 orders every month.

For any additional features, or the ability to scale up, these free software platforms will charge monthly fees, usually dependent on the number of users, number of products being managed, and number of orders processed.

For any company that operates at a scale larger than that of a startup or boutique, these pricing models can create exorbitant invoices for your company – and at the enterprise level, these solutions lack any form of ROI, and quickly become a burden to your bottom line.”

Even enterprise level software can fail to truly meet the standard of market fluidity national and multi-national brands face. While many ERP systems are designed to be customized to various industries, this is akin to designing your own app with a drag-and-drop software.

Options such as these also lack true integration within your environment – these platforms are intended to replace aspects of, or even the entirety of your enterprise environment, and not to work within the architecture your company has worked with for years.

Enterprise environments take years, sometimes even decades to truly be implemented, and they are continuously adapting and upgrading as technology improves and markets dictate more speed and customer value. Brands that can truly be classified as “enterprise level” are no different – cultivating a national or multinational brand is an undertaking that can take a full generation, and requires continuous observation and tinkering to keep growing, and stay relevant in the public’s eye.

For a brand that took twenty years to rise to the level that it is now, it is much smarter to invest in the future, rather than the present – and using an proprietary third party software for inventory management is investing for the short term rather than the long term.

Finally, many inventory management systems lack mobile integration – a necessity to maintain speed and efficiency in a truly connected enterprise environment.

Customized solutions increase efficiency

An inventory management system can do a lot more than tell you when levels are low on a certain product. With a custom platform fully integrated within the rest of your ERP environment, you can track detailed data points such as a product’s physical location in your warehouse, or the system can automatically determine the optimal time for re-ordering products: based on data points such as available shipping routes or closest supplier, and even down to weather patterns that might effect delivery schedules.

A more sophisticated inventory management system goes beyond tracking the sale of a type of product – with RFID integration, when scanned by your POS system, individual products can be tracked and recorded as they are sold. With data as intricate as this, a custom inventory platform is able to aggregate sales data in order to automatically generate reports that provide insight into optimal production times and when demand increases or decreases.

When working with a custom inventory management system, all of this data will automatically populate in their respective reports for your different departments, warehouses, and offices – whether spread throughout town, or across the globe. Via realtime integration, your service team in St. Louis will be aware of a part being shipped out from New Delhi, and your accounting firm in New York will receive the purchase order.

A system such as this provides you with a detailed view of the entire history of a product – from production to the final sale. This can be further broken down into the order history of each part, that when pieced together create a finished product – meaning you can analyze the intricacies of your entire operations through a single program.

Most importantly, all of these features can be accessed and utilized via mobile device – meaning your business developers out in the field have the latest data, and your CCO in Denmark has access to the latest numbers.

A major benefit to custom inventory management solutions is the fact that your internal IT department needn’t learn new systems architecture and languages, or restructure to fit the limitations of a piece of third party software – when built custom, languages that are commonly used throughout legacy systems, like .NET or COBOL are valid options. This isn’t so with proprietary software.

Improve customer value and satisfaction

A custom inventory platform, when fully integrated within your enterprise environment, is an efficient method for increasing your customer satisfaction. This is the ultimate goal of an inventory management system – customers can reliably count on your item stock, and B2B connections can trust your operations and records.

With the additional insight big data analytics can provide your production and sales, your enterprise can take the next leap towards continual improvement in efficiency.

How to find and work with a freelance mobile developer

/0 Comments/in , , /by

Sometimes, hiring a freelance developer is the only option you have – whether it’s due to budget concerns, or the need to fill-in a missing link in your internal IT department is too pressing to conduct a search using your own resources and time.

Freelance developers come with the benefit of a lower hourly rate – but if not carefully vetted, prepared, and managed, freelancers’ benefits can be overshadowed by never-ending development cycles, un-met goals, and low-quality products.

Finding a freelance developer

When searching for a freelance developer, nothing is better than a referral from a trusted source – if that isn’t an option, however, there are a few sites online you can trust, and many you should do your best to avoid.

One such site that you can trust is TopTal. The Android and iOS developers that you’ll find on TopTal have been vetted, and only the top 3% of talent is accepted. The developers on this site all come with proven track records, and verifiable experience.

TopTal even offers their own form of freelance project management; a TopTal representative will keep track of your project’s progress, as well as making sure you remain satisfied with the level of work being produced.

Another site that heavily vets freelance developers is Hired. This company only accepts the top 5% of freelance developers, in a similar fashion as TopTal. Just like TopTal, Hired will only accept developers with extensive experience in the industry.

The last site we’re going to cover is gun.io. If you’re a company looking to fill in a skill gap in your development team, gun.io has you covered – they specialize in finding the best talent for your development and engineering departments. gun.io also, (like TopTal and Hired) vets candidates throughly, so you can expect a candidate who knows what they’re doing.

There is one issue with going the route of upper-echelon freelance talent, however: hourly rate. Due to these companies listed above doing so much vetting (and sometimes project management) of their own, you’ll be paying a much higher hourly rate than when compared to the usual rates you’ll find on a site like Upwork or Fiverr.

We also highly encourage you to make sure your freelance developer goes through your own vetting process, in order to make sure they will work well within the framework of your team or company.

Working with a freelance developer

When working with a freelance developer, the most important step you can take to ensure a productive development cycle is to quickly establish a strong line of communication – if you can afford it, face-to-face meetings are always the best way to start building the relationship necessary to develop an app.

Also, make use of as many communication tools as possible – this can include video, messaging services like Slack, phone, and of course email. Make sure to set the tone yourself – be the first one to reach out after a contract has been signed. You’ll want to make sure your project manager assigned to your freelance developer is quickly responding to communications from them – freelancers also expect clients to be responsive.

This is because if your freelance developer has a question, they won’t be able to proceed until you have answered it. Even if the project manage doesn’t have the answer in that instant, they should respond with a quick message explaining that they have seen the communication, and are working to find the answer.

If a freelance developer feels like they are being ignored, they will move on to a different project with one of their other clients – the majority of freelancers work with multiple clients – so you’ll need to be extra attentive to any questions that will arise during your app’s development.

During the building of this new business relationship, you’ll want to set clear goals for the product you expect, and the gates of approval your freelance developer should expect. It is best if you can have a clearly defined tech doc detailing the features and capabilities of the product you want.

Also make sure to provide samples of what you would like your final product to look like – this will help during the design phase from reiterating and editing work, which can severely bloat the budget of your project before it even truly begins.

Another good practice is to hire a consultant to check over the code your freelance developer has produced – you’ll want to make sure the code that is written is easily decipherable. If it isn’t, you might have to start the development process over again as soon as your app needs to be updated.

Freelance developers make a living by continuously taking on and completing projects – it is rare to find a freelancer who is willing to stay available for a single client, and because of this, you’ll most likely need to find a new freelance developer when the time comes to update your app.

For this reason you’ll want to make sure the codebase produced is incredibly robust and well-structured, or else you’ll be forced to choose between abandoning the codebase, or waiting for the freelance developer to become available again (which in some cases, can take months).

Freelancers can be either be a blessing or a burden

With careful planning, attentive management, and open communication you have a good chance of developing a great app. By ensuring your codebase is strong and easily readable, you can make sure your app stands up to the test of continuous updates.

Improving your company’s productivity with an enterprise app

/0 Comments/in , , /by

Every business stands to boost their employee productivity, and therefore their revenue through the integration of their internal systems with an enterprise platform. The development of a true enterprise platform doesn’t just mean an app your employees can access via their smartphone – in essence, enterprise platforms are designed with the purpose of optimizing your work processes, systems, and communication.

There’s never been a better time to deploy your very own enterprise app – AI enhanced analytical services are more affordable than ever before, and industry legacy systems are quickly getting outpaced by their big-data-optimized counterparts – soon, companies that don’t make use of their own enterprise platform will find their speed as a company lagging behind competition, and their employees leaving in favor of a company more engaged with its workforce.

The impact of enterprise app deployment

According to a report from software giant Adobe, companies that invest in an enterprise platform see a 35% ROI. A substantial number of companies reported increased productivity (51%), as well as better employee communication (47%), and reduced operating costs (31%).

Numbers like these are nothing to ignore – which is why, according to the same report, 67% of businesses are using an enterprise app. Many of the same problems enterprise apps help to alleviate are widespread concerns throughout different industries: 55% of companies site the need for improved communication, and 54% of companies struggle to keep up with their ever growing mobile workforce.

Enterprise apps, are, of course, the best tool for improving employee communications and connectedness – whether in the office or out in the field.

Productivity through connectivity

Over half of the companies from this report acknowledge that staying connected with their employees out in the field is a prescient issue, and according to a poll from Gallup, 70% of the workforce is disengaged – reasons reported include:

  • Lack of feedback or direction from their manage
  • Lack of socialization with their team
  • Lack of understanding of company mission and values
  • Lack of proper communication between the employee and manager

      • When you’re an employee out in the field doing maintenance on an HVAC system or switch hub, or a business developer building relationships with potential clients, it’s easy to feel detached from the company you work for.

      It’s even easier to fall out of the loop – today’s business environment is one of continuous change, every minute of every day. A business developer needs to know the latest market forecast based on stock data, the latest environmental regulations for building permits, if the potential client’s favorite team is playing that week.

      Knowing the fine details your clients will care about is key to driving sales – and no business developer has the time to keep up with all of these data points for every potential client. Building client profiles based on specific verticals that automatically aggregate pertinent data is the most efficient method of keeping your business developers who are out in the field continuously on top of their game – and continuously impressing clients with their personalized conversations and service.

      Enterprise systems do more than keeping your employees in the loop; they are highly efficient at tracking and organizing physical inventory as well. Via an enterprise platform your sales, service, and accounting departments can view the same inventory data in real time. Enterprise systems are built to work within your already existent environment, and can therefore connect the individual systems these departments use.

      For instance, if your service department sells an item to a customer at a store, your accounting team will be notified of the sale immediately before submitting a new revenue report – just as your sales manager is made aware of the change in the item lot size before shaking hands with a client who wants the same item.

      Enterprise systems don’t just connect individual departments’ ability to manage inventory – it also helps your company predict when sales will happen, and when the optimal time to order more inventory will be, based on patterns that are recognizable through big data analytics. When you can optimize your ordering times, you maximize your inventory turnaround, and increase your ability to manage more product, or more types of products.

      Big data is the key to optimization

      When combined with AI, analytics, and machine learning, big data gives enterprises the information they need in order to stay a step ahead of their competition through inferred business intelligence.

      Overwhelmingly, throughout recent years, the vast majority of data that has been created is classified as “unstructured” data – meaning it is data found in documents like emails, recordings, telecommunications, video – and only 0.5% of it has been analyzed.

      Enterprises, unsurprisingly, sit on a proverbial mountain of this unstructured data – and via predictive analytics and other forms of data aggregation systems, these companies can access and analyze big data more intricately and faster than ever before.

      Through big data, companies can recognize patterns that interrupt workflow and productivity that might otherwise be unrecognizable without viewing the problem with the scope big data analytics makes possible.

      Take, for instance, the decision of UPS to not make left turns; they invested in a software that mapped the United States (as well as most of the world), in order to nearly eradicate left turns from their parcel delivery truck routes. This decision ended up saving the company over 20 million gallons of fuel every year. Without big data, creating these avenues for efficiency is impossible, or less efficient than it would be with big data integration.

      Venture ahead via enterprise platforms

      Improving your company’s productivity requires more than just a mobile app – a truly integrated system must work within your enterprise environment as soon as it is deployed. For more about proper deployment, visit our blog on the topic: Enterprise app development.

      An enterprise platform gives your company the ability to improve productivity, communications, systems management, and employee loyalty via one system – and simultaneously gives you a leg up on your competition.

Onshore vs. offshore: Cost vs. value

/0 Comments/in , , , /by

We live in a truly global age – theoretically, there’s nothing stopping you from picking up your phone and video chatting someone in Nepal, other than the fact that you probably don’t have a contact that lives in Nepal (or, if you’re reading this from Nepal, video chatting with someone in Paris, Texas).

If you’re reading this from the US, there’s a few good reasons you don’t have a contact who lives in Nepal (unless you do have a contact who lives in Nepal): time, distance, and language. It’s pretty difficult to create a relationship with someone who’s asleep when you’re awake, lives 6,000 miles away, and doesn’t speak the same language as you.

As this piece published by Medium states, offshore software development can potentially be four times cheaper than software built in the US or Europe, but for the reasons listed above – and more which we’ll cover below – when put into practice, offshore development usually ends up costing you more money.

Why? As we’ve written about before, the cost of app development (and any form of software development, in fact) comes down to the following equation: feature set + scale + hourly rate = total development cost.

Yes, hourly rate is one of the major determining factors to the cost of development, and yes, offshore development tends to be cheaper than onshore – but, so too are feature set and scale included in the equation. Development of an app’s feature set requires significant communication between developers and clients, and as distance increases, so to does your operating scale.

Distance = time

Unsurprisingly, the majority of differences between onshore and offshore development arise from distance more than anything else – even if both parties are speaking the same native language, a choppy wi-fi signal, when transmitted internationally, can cause major disruption to communication comprehension. This problem is of course compounded when accounting for language barriers.

There’s more to distance than its purely physical definition – cultural distance is a major disruptor to the time it takes to develop an app. UI design is a language unto itself, and depending on what culture your designer is from, you many not be supplied with a UI that fits the tastes of your target market.

Take, for instance, this app made for the Brazilian market. For many users in less-digitally-developed countries, smartphones are their only method of accessing the internet. Therefore, apps are designed to do as many things as possible, and utilize bright color palettes to convey feeling rather than responsiveness and tight animations that exemplify onshore UI design.

This does mean, however, that when creating an app that is to be used across multiple countries and cultures, it’s best to find designers from each region to create region-specific layouts, in order to best attract your individual niche markets.

Finally, as we previously mentioned above, there is always the logistical aspect of developing an app with someone half-a-world away. Questions about current build iterations usually come up at the beginning of the day, not the end – which when working with a team on a 12-hour time delay, can equate to a full day of work lost for that particular developer.

If a developer has a question at the start of their day for you, and your day doesn’t start for another twelve, there’s no way for that developer to progress – full-day-delays can lead to adding an entire extra week onto your development timeline over the course of a project measured in weeks; and for projects measured in months, entire extra seasons can be added onto your turn-around time.

Communication

An iOS app developed in India is written using the same language as one developed in the US. Software languages don’t change depending on the developer’s geographical location – but documentation does.

Clear documentation is absolutely necessary to a successful software handoff – if you’re a company with your own internal IT department, you might be forced to spend significant amounts of time either reading tens of thousands of lines of code, or talking to your offshore development team for clarification.

Improper documentation doesn’t just cause problems during development – it causes deployment issues during updates as well. It’s smart to estimate your time spent communicating with your offshore team will take four times as long as it would when compared to an on-shore team, when accounting for delays caused by language barriers and timezone differences.

Logistics

Working closely with an offshore developer can create nightmarish amounts of red tape. Scheduling a meeting with an offshore developer can mean paying for multiple international tickets, hotel expenses, meals, visas, and much more. It shouldn’t cost your company thousands of dollars to hold one face-to-face client meeting.

There’s a reason in-person meetings are so important – meeting with a potential business partner in real life is the best way to determine whether or not you should place your trust in them. Placing your trust in a company that has no personal connection to you can lead to some severe repercussions, especially when paired with the more lax security and privacy laws offshore developers are subjected to.

IPs are also less protected when developed offshore, and if your intellectual property is stolen, your international legal fees can add substantial bloat to your operational budget.

Everyone knows the old saying “you get what you pay for,” and in regards to offshore vs. onshore development, this adage still rings true. Domestic developers have more of a stake in maintaining their reputation with clients, as offshore developers have the ability to move from project to project without repercussion – meaning the quality of your app’s code can suffer over time as it deteriorates from lack of updates.

With a domestic developer, you’re much more likely to receive an upgradable, adaptable, and understandable codebase for your app – don’t sacrifice long-term stability for short term profits.

Enterprise app development

/0 Comments/in , , /by

Enterprise app development is more than simply building an app for a business – an enterprise developer must account for a multitude of challenges, including complex and vast internal systems, legacy software, manual processes, deploying within an already existing environment, and much more.

Having the ability to quickly integrate a corporation’s highly intricate and intertwined internal business systems within a single mobile software solution requires an entirely different skill set than other forms of software development; it necessitates that the developer understands both the corporation’s systems as well as their app’s system architecture.

In short, there’s a big difference between developing an app for an entrepreneur with an idea, or an enterprise level business with a plan for complete mobile integration throughout their existing systems.

Developing for enterprise

Successful deployment in an enterprise environment is akin to changing a car’s tire while maintaining speed – but with careful planning, clear documentation, and the creation of replicative test environments, it can be achieved.

The following are processes most enterprises should consider when planning for the development of a system-integrating app:

  • Change management
  • Project management
  • Approval gates
  • Environment integration

Also be aware that for your own internal IT department, a software development project precludes the signs of increased risk and systems maintenance – below, you’ll find steps your development partner can take in order to minimize the burden put on your own IT department.

Enterprise structure

Structuring an app to the enterprise environment requires significant communication and documentation – the ultimate goal of any enterprise software development is to ensure your development partner properly manages the project, so you own IT department can continue to focus on ITSM and ITIL.

In order to achieve this, your development partner should always provide you with a statement of work that covers all assumptions – this helps to ensure time spent in development is used efficiently, and helps alleviate speed bumps if changes arise such as an increase in burn rate.

There is no such thing as too much documentation – it’s a good idea to make it a rule that in order for any change to pass through your change approval and governance gates, the change must include supporting documentation. This helps to take some of the burden of learning an entirely new system away from your internal IT department.

Doing so will also both simplify and quicken the process of ultimately handing off management of your new enterprise software to your internal IT department – the proverbial changing of the tire.

Before any development begins, it’s important to make sure your BSA has throughly run through the entirety of the proposed app’s feature set, systems architecture, process structure, and risk assessment. After the entirety of the tech stack is defined (define your tech stack as early as possible), and requirements gathering is complete (for enterprise apps, this usually consists of large quantities of data aggregation), development can begin.

Deploying in the enterprise environment

Most enterprise systems are spread out across multiple environments – requiring communication between multiple types of applications, devices, APIs, and data.

Gone are the days when an ESB (enterprise service bus) would suffice – this centralized methodology of technology and teams causes a bottleneck in the flow of information and delay integration between the components of your business systems. A distributed system architecture with multiple reusable endpoints such as this is both more robust and more adaptive than the old ESB model as well.

In order to effectively integrate with an environment that allows for communication between multiple systems and layers, you’ll need to ensure your development partner allocates enough time to test your under-development app in a replicative environment. If your environment exists on premise or in the cloud, you’ll need to account for that during testing. Utilizing all devices that will be integrated – from routers to smartphones – is essential too.

To fully integrate your various systems, you’ll need to make use of messaging, application connectors, data streams, enterprise integration patterns, and APIs throughout your enterprise environment – depending on your data and architecture needs, some of these may be unnecessary.

Messaging

Messaging provides a channel for the various components in a distributed system through which to communicate with each other. This allows components to both send and receive messages in different languages, compliers, and even operating systems – messages can all be read with the use of one unified format and protocol.

Application connectors

These architectural elements provide the rules for how components interact with each other. Because they are standard class connections that are customizable to APIs, they can be quickly integrated with new endpoints.

Data streams

Aptly named, data streams provide an avenue for a continuous flow of data that applications distributed throughout your architecture can add to or consume from, independent of the data that is being transferred.

Enterprise integrations patterns

Referred to as EIPs, these are collections of solutions to common integration problems – these rely heavily on proper and through software documentation.

Application programming interfaces

APIs are a set of tools, definitions, and protocols that provides functionality in the form of a feature set by communicating with, and requesting data from a different set of software that does not require implementation.

How to choose your enterprise development partner

While it may be tough to convince your CFO, it’s much more important to pick the development company with a robust management structure and portfolio over the developer with the lower hourly rate.

Knowing your app is properly managed during development is a much better factor for determining the total cost of its development than comparing hourly rates. Mismanaged software can lead to delays measured in months, or sometimes, even years.

Take this example of the nationally-renowned web dev company Accenture and their mismanagement of website redevelopment for the car rental company Hertz. Hertz paid the web developer $32 million – and still didn’t have a functional website.

If you want to ensure smooth development for your enterprise-level app, always choose the partner that displays the most knowledge about your specific needs as a business.
