Agile And Waterfall Methodology: 5 Things To Know

/0 Comments/in , , , , /by

As a business leader, you’ve probably deliberated over the differences between the Agile and Waterfall methodology. And if you’re an app developer, you’ve likely adopted one of these two methodologies to complete your projects. 

But you’ve probably heard project managers and industry insiders throw the terms ‘Agile’ and ‘Waterfall’ quite liberally. Thus, often giving the impression that both are similar, even though this isn’t necessarily true. 

Sure, both are popular methodologies that involve the planning, realization, and keeping track of projects as they advance. However, there are several glaring differences between the two that we need to understand clearly.

So, what are the differences between the Agile and Waterfall methodology? There are several, but we’ll focus on one key difference right now. 

Agile relies on continuous iteration whereby the development team works simultaneously on a project, making it a flexible model. However, Waterfall requires the team to complete each stage of the project linearly, and thus, it’s way more rigid. 

But let’s be clear about one thing, neither methodology is better than the other. Project managers must pick the one that best suits their needs. And to better understand the differences between the two and which to pick, we’ve compiled this handy list below to help you make the right decision! 

1. Agile Methodology In A Nutshell

Due to the more strict nature of Waterfall, it soon became necessary for an alternative. And thus, Agile made its way into the world of project management to address a common problem. Since it often takes many years to complete most common software projects, technology undergoes tremendous change. Henceforth, development teams cannot realistically complete their projects while keeping up with customer demand with the Waterfall methodology.

But with the flexibility of Agile, it’s easy to make changes, even late during the timeline of a project. Moreover, company stakeholders, management, and customers may request changes or new features. It’s even possible to implement these additional changes or features without hindering the project significantly. 

And that’s because Agile allows the team to complete several phases concurrently and frequently. Another benefit of Agile is that the team determines the project’s direction instead of the project manager. Ultimately, this energizes the team and helps increase productivity, but it also calls for more team independence.

2. Understanding The Waterfall Methodology

Projects with a known outcome benefit immensely from the Waterfall methodology due to its linear approach. Before a team can move forward, it must first meet the set requirements and complete the deliverables of the current stage of the project.

However, the project lead must have a well-defined vision for the app. More importantly, no major alterations may occur during the development process, as this will likely derail the project. Unlike with Agile, it’s difficult and costly to course correct with the Waterfall methodology.

And before a project commences, the project lead must have a clear picture of the budget and timeline. Any deviation from this during the development process will put the project at risk. However, this does not necessarily make Waterfall projects riskier than Agile projects.

3. Agile And Waterfall Methodology Impact Client Involvement

Depending on the scope of your project, you may decide to involve your clients. If that’s the case, then Agile is a great choice. And according to the Principles behind the Agile Manifesto, customer collaboration plays a vital role. Furthermore, it encourages collaboration between developers and business people and face-to-face discussion on a frequent basis.

With Waterfall, if you’re the project lead, you’ll hold weekly or monthly meetings with your development team. And you may share progress reports with company stakeholders, but you won’t collaborate with clients. Furthermore, you’ll only share information on a need-to-know basis with the right people in your team.

4. Rigid Versus Sprint Planning

With the Waterfall methodology, the planning phase takes far longer than with Agile. And that’s because the project lead and company stakeholders must evaluate the feasibility of the project. In most cases, the budget will be higher, as a Waterfall project must be completed in its entirety before it’s shipped.

Furthermore, there’s very little wiggle room, if any, for changes at a later stage. Any decisions taken during the planning phase must be adhered to during the entirety of the project. And to ensure that the development team remains committed to the project, the planning phase also includes the monitoring procedure.

Agile is an entirely different beast, which doesn’t prioritize planning. Instead, projects are broken down into sprints, and decisions that will impact the project occur before each sprint. These sessions are also known as sprint planning. And while Agile offers plenty of flexibility, major project changes may not occur during an active sprint.

Keep in mind that Agile requires constant engagement by the project manager and team members. Therefore, stand-up meetings have become customary for teams to stay informed. All attendees must meet regularly for small durations and must stand while the project lead updates the team in front of a whiteboard. 

Stand-up meetings may occur every day or several times per week. In most cases, stand-up meetings work remarkably well. But difficult to implement with large teams spread across multiple locations. Also, holding too many stand-up meetings may disrupt the workflow of the team. 

5. The Waterfall Methodology Is Losing Popularity

As you’re probably aware by now, Agile seems to have advantages that make it very attractive to development teams. And given the shift to Software-as-a-Service (SaaS) from packaged software, Agile makes perfect sense. But it doesn’t end there, as many mobile app development teams rely heavily on a continuous iteration process.

Most savvy mobile app developers start with a prototype or a minimum viable product (MVP). And if these gain traction with users, then they’ll scale up to a full-fledged product. But given the constant introduction of new mobile devices and app store requirements, most mobile apps are not truly ever done.

And let’s not forget that users have become accustomed to receiving features that will keep them engaged after each app update. Therefore, the Waterfall methodology isn’t suitable for most mobile app development purposes. It’s better to adopt the Agile methodology and introduce new features and updates during every active sprint.

But don’t write off Waterfall entirely, as it may prove useful if you’re developing a premium mobile game. Most paid mobile games have high-quality visuals, gameplay, and features that make them closely resemble console games. And thus, it’s unlikely that you’ll introduce new content and features later unless these come in the form of downloadable content (DLC) or in-app purchases (IAP). 

Even so, most premium games have a limited lifecycle, so don’t necessarily require continuous iteration. Their high budgets, long development cycles, and the necessity for specialist team member roles make the Waterfall methodology the right choice here. 

In Conclusion

Understanding the key differences between the Agile and Waterfall methodology places you in an advantageous position. It allows you to opt for the right methodology that best suits your project. However, company stakeholders will also affect your choice.

For example, if these stakeholders will support the project long-term and closely involve themselves, Agile is the way to go. But if these stakeholders prefer a more hands-off approach, consider Waterfall instead.

The Secrets of Perfecting An App Update

Chances are, if you’re reading this, you’re an app-user yourself. That means that, most likely anyway, you’ve been annoyed, interrupted, or frustrated with an app update. This is because many developers and app programmers have yet to find the app update sweet spot. In other words, with today’s knowledge and data, there are plenty of tricks to the trade, so to speak, when it comes to app updates.

Certainly, finding the frequency with which to release app updates is one of the steepest mountains to climb. However, there are other important considerations to take into account as well. Factors like cost, the time-of-the-update, and how users are notified have an impact as well.

Keeping Updates User Friendly

The user experience is arguably the most important aspect of an application. This is simply because the app-market is so heavily saturated with options and competition; such that a single negative experience is capable of driving a user to a competitor’s platform. This principle extends through the entire process of app development, from design and functionality, to the app updates, and overall usability of the application.

Correspondingly, it’s vital that app updates maintain the set-standard in regards to user experience and be as easy to manage as possible. By releasing regularly planned app-updates at as convenient as times as possible, shows a dedication to your user base that in turn generates additional user-loyalty and extended log-times.

How Frequently Should You Run an App Update?

Now, for the real question. Just how often should you be running an app update? While the answer varies slightly depending a few factors, industry standards suggest no fewer than once a month. With the rate at which technology is advancing, and the frequency with which we use applications one update/month is truly necessary.

There are plenty of reasons to run app updates, for example, if your users even experience one bug with your application; they’ll likely jump ship at the drop of a hat. Running an app update prevents bugs from running rampant in your application. Furthermore, app updates ensure that user-feedback is being heard and implemented throughout the lifetime of the application.

While one update/month is the accepted minimum in todays app-economy; current data suggests that more robust applications undergo up to four updates/month.

Don’t Let Updates Go Ignored

Finally, it’s important that users actually download the app updates you run. This is vital because without running the updates, users open themselves up to security risks, and faulty application functionality. However, most applications in today’s market have the ability to push users to the app store for important updates, which ensures that users download the most current version, as outdated copies simply lose device-compatibility entirely.

A Quick Recap

Running app updates is a tricky, but core element to building long-lasting applications that soar to the top of the app-store. Run at least a monthly app update; continue prioritizing the user experience; and ensure that only the latest version is kept active, and elevate your app updating process.

Understanding The Application Lifecycle

Application Lifecycle Management 

There is a beginning to everything. In fact, nothing comes into existence out of nothingness. The universe, for instance, as we understand, came to be through a massive eruption of energy known to science as the big-bang. While the creation of an application may not begin with a universal eruption, its conception is thrilling all the same. Whether this is your first-ever application, or your thousandth, understanding application lifecycle management will boost your workflow and elevate your efficiency from the start. 

There are three main aspects of application lifecycle management (ALM). Those three aspects are: 

  • Governance
  • Development and Deployment
  • Maintenance

These are the different phases of an application from start to finish. The first two phases are definite, while the last is ongoing. In other words, once the app is live – there will always be ongoing maintenance activities to perform. 

Having a strong grasp of application lifecycle management builds innate value into the business. This value emerges in the workflow, processes, and procedures all associated with application development. By understanding the application lifecycle, developers implement best-practices and industry standards into their design process, therefore boosting efficiency, and resulting in higher quality applications. 

Governance

Governance is the very first phase that begins the journey of an application. As soon as the app is conceptualized, the governance phase has begun. Governance, in this context, isn’t referring to the laws and rules of a nation. In a similar sense, however, governance in the context of app development refers to defining core aspects of the application. 

The elements that need to be defined in the governance phase of the application lifecycle management include a spectrum from function, to logic, and framework. In other words, this is the phase in which designers are able to verbally identify the various pathways, functions, and workflows. 

Having an idea of how the application is going to flow and function is crucial to entering the next phase of ALM. A good way to think about the governance phase of the application lifecycle is to imagine it as a blueprint. The blueprint informs the construction crew on how to actually raise the structure, the dimensions of the individual pieces, and how they all fit together. 

In the same vein, the governance phase of the application lifecycle should result in an easy-to-follow development roadmap. 

Development & Deployment in the Application Lifecycle

This is the phase following governance. Development and deployment are actually two halves to the whole. Development is the first piece in this phase. The development phase is where the application is actually built.

Additionally, there is a third aspect to development and deployment that impacts both phases: consumer and market testing. Testing is a not a formal phase of the application lifecycle management however, it is nonetheless critical to delivering applications that are of value and that consumers desire.

Delving Into Development

There are many aspects of the development phase. As such, this is arguably the most crucial phase in ALM. Since the development phase is equivalent to the actual construction phase in real estate development. In other words, developers are laying the foundation for the app. A strong foundation provides the platform for a well-designed and successful app. 

Developers have more on their plate than mere function however. App development teams task themselves with the visual design and work-flow of the application in addition to the functionality and usability. Once developers reach a certain level of baseline functionality, the application starts to enter the next half of this phase: testing and deployment. 

Testing

The first round of development yields an MVP: minimum viable product. Firms and developers use MVP’s as samples of the end-product in order to gain additional consumer insight. Companies use this insight to make important decisions on how to finish the development phase. 

In market-testing, consumers are asked about multiple aspects of the app. These aspects range from the aesthetic and color-scheme, to the actual function and usability of the app. 

After the focus groups and market-testing, the MVP returns to the developers with loads of notes, comments, and real consumer input. Developers use this invaluable insight in order to finish the build of the application and deliver a functional app that solves real consumer issues.

While it’s unwise to spend too long on any single phase of the application lifecycle, testing is certainly not an area to start cutting corners. Using focus groups and market-testing delivers immense value to the final development of the application. As such, these activities should actually be supplemented, if anything, in order to test the MVP on multiple demographics. 

Deployment

At this point, the application, its function and workflow, and its usability have been defined. The core build is tested, and the final development, influenced by consumer input and marketing test-groups, is complete. Finally, the sweet fruit of the labor is in reach, and the application lifecycle nears its final stage. 

The deployment of an application upon its completion is certainly not the most laborious of the phases, however it is very fickle. Firms need to start developing their deployment strategy in the early steps of the governance phase. This is because the governance phase will help dictate and define the proper channels of deployment to utilize. 

The testing phases will also contribute to developing the deployment strategy, as it will offer real insight into where consumers want to find the application, and how they will use it. Speaking to the core values of your main target-demographics, and ensuring that they have easy access to your application are crucial to releasing a successful application that draws consumers inward. 

Ongoing Maintenance

Ongoing application maintenance is crucial to user-retention and future user-acquisition. The application marketplace is already supersaturated with options for the consumer. As such, user-acquisition and user-retention are already hyper-competitive areas. User retention is especially important because it forms the regular user-base for the application. 

Since a robust regular user-base is one of the most valuable commodities in the application market, maintaining this user-base is critical to longevity. This is, in part, due to how fickle user-ship is in the application market. Users are prone to jump to a competitor with a stronger user-experience after a single negative interaction with an application. 

This type of rapid turn-over puts a strong emphasis on user-loyalty. Beyond that, if applications are left unmaintained and unattended to, their functionality will deteriorate, their security protocols will begin to weaken, and users will swiftly abandon ship. 

The Benefits of Application Lifecycle Management

The application lifecycle begins with ideation and governance, moves through development, testing and deployment, and ends with on-going maintenance. Developing applications by putting them through these different phases occurs naturally. However, identifying the phases and understanding how they relate to one another allows companies to build stronger and more efficient workflows. 

Firms can customize the workflow to fit their specific needs, while still adhering to best-practices and industry-recognized standards. Following through on the phases and their associated actions ensures that released applications are thoroughly vetted, and ready for mass use.
