Why is the agile development method very necessary for creating mobile applications?

Before you can understand the agile mobile app development method, you need to understand the mobile app development process. Any app installed on a smartphone, game, or social network requires many factors to work properly. Factors to consider:
  • App Idea
  • Design
  • Development
  • Execution and publication
  • Testing
If any of these factors are violated, problems arise, such as: violation of deadlines, loss of finances, outflow of employees, and other difficulties at the implementation stage. The development of mobile applications is the result of a lot of work done by specialists from different fields, and, most importantly, constant negotiations between the client and the company engaged in the development of mobile applications. Any software, including mobile applications, can be considered as the result of proper and high-quality interaction.. Agile mobile app development is one of the most effective approaches for all software development companies, and provides a proper communication channel that helps both customers and app developers execute the desired mobile app or virtually any software.

What is a flexible methodology?

The exact value of Agile lies in the rapid implementation of changes and changes in a moving project. The same applies to the agile methodology. As for the project management method, which I described as dividing tasks into short stages of work and frequently re-evaluating and adapting plans. Flexible features simplify the development of mobile applications, so that the results of the mobile application can be adapted after its publication. Let's talk more about Agile, see what principles of software development are used. There are only 12 of them.
  • Customer satisfaction through timely and continuous software delivery
  • Changing requirements are welcome, even at a late stage of development, that is, some edits
  • Running software is delivered frequently, meaning the stakes are integrated and released regularly
  • Close, daily cooperation between the customer and the developer
  • Projects are built around motivated people who are trusted
  • Face-to-face conversation is the best form of communication (recently less and less relevant, but still...)
  • Working software is the main indicator of progress
  • Sustainable development, able to maintain a constant pace
  • Constant attention to technical excellence and good design
  • Simplicity is a very important art to maximize the amount of work in progress
  • The best architectures, requirements, and projects are created by self-organizing teams.
  • The team regularly reflects on how to become more effective, and adjust their actions accordingly.
Agile does a great job with all these tasks.But now the question arises as to how much better it is compared to the waterfall methodology. Which one do you think is best suited for mobile app development?

Agile or Waterfall methodology?

Let's take a quick look and then compare them side by side.

What is the Waterfall methodology?
The waterfall methodology is very similar to the construction and production processes, a sequential design process. This means that at the end of each of the eight stages (concept, launch, analysis, design, development, testing, implementation, and maintenance), developers move on to the next stage. This process is completely consistent. Only after one step is completed and implemented, the developer moves on to the next. If he wants to go back to the previous stage, everything must start from the beginning. There is no room for mistakes or changes, so the project result and detailed plan should be established at the very beginning, and then carefully followed. Now let's discuss the main differences between these two methods.
  • Waterfall has a structure, and you need to follow it, and trust me, it can be quite rigid, and the Agile methodology is known for its flexibility, which is the reason that most mobile app development companies go for it.
  • The development of the mobile app should be completed as a single project under a cascading methodology, which is then divided into different phases, with each phase appearing only once during the SDLC.
However, the Agile methodology can be viewed as a collection of many different projects that are nothing more than iterations of various stages aimed at improving the overall quality of the software with feedback from users or the QA team.
  • If you decide to use the waterfall methodology for developing mobile applications, you need to clearly state all the requirements, since you will not be able to change them after the project is launched.
On the other hand, the agile methodology is really flexible and allows you to make changes to the project development requirements even after the initial planning is completed.
  • All stages of project development, such as design, development, testing, etc., are performed once in a cascading model, while within the agile methodology, they follow an iterative approach to development. As a result, planning, developing, prototyping, and developing other software
  • Phases can appear more than once during SDLC
One of the main differences between them is an individual approach to quality and testing. In the cascade model, the "testing" phase follows the "embedded" phase, but in the agile methodology, testing is usually performed simultaneously with programming, or at least in the same iteration as programming.
  • While the waterfall methodology is an internal process and does not require customer participation, the agile software development approach is focused on customer satisfaction and thus involves customer participation throughout the development phase.
  • Waterfall methodology can be defined as a strictly sequential process, but agile methodology is a collaborative software development process that results in better team input and faster problem solving.
  • The Waterfall methodology is best suited for projects that have clearly defined requirements and where no changes are expected at all, while Agile supports a process in which requirements must change and evolve.
Therefore, if you plan to develop software that will require changes in the process and must meet the technological landscape and customer requirements, it is best to follow a flexible methodology.
  • Finally, Waterfall demonstrates project thinking and focuses strictly on completing project development, while Agile represents product thinking, which focuses on ensuring that the developed product satisfies its end customers and changes according to customer requirements.

So what exactly is the need for a flexible mobile app development methodology?

  • Agile will be very useful when you need fast production rather than product quality.
  • Your clients will be able to change the scale of the project at any time.
  • If you don't know what the end product should look like, you should definitely switch to agile.
  • If you, the developers, are very talented, believe that they are able to adapt and think independently, Agile is definitely right for you.
  • This is really useful for mobile app development, because expectations and standards change quickly, and Agile adapts easily.
