The 3 App Development Methodologies To Understand

To develop a successful application, the process of designing, assembling, and the final actualizing and integration is your road to gold. It very well may be finished by gigantic associations with substantial groups chipping away at activities, or by a solitary independent engineer. App development is characterised by its process, which commonly follows a standard methodology.

Application development is firmly connected with the software development life-cycle (SDLC). The essential phases of cycle are:

  • Planning
  • Analysis
  • Design
  • Construction
  • Testing
  • Implementation
  • Support

The manner in which that application development group achieves these seven aims has evolved greatly over the recent decades, and various application development strategies arising. However, every methodology should answer the seven phases of the SDLC regardless.

Most application development procedures can be gathered into one of three classifications: Waterfall, RAD, and Agile.


The main features of the waterfall strategy are planning and sequence. The whole project is mapped out in the planning and analysis stages. The client accompanies a clear rundown of features and functionalities for the app. At that point, a project manager is in charge of the entire process and constantly updates the group.

Once you go down a waterfall, you can’t return up. Similarly, this app development technique functions just like its namesake. The development team cooperates over a lot of time, creating what is lined out as per the requirements. After the wireframes are designed and decided upon, the engineering of the app begins. The whole application is created and tested thoroughly to ensure that it works smoothly. At that point, it is presented to the client and prepared to be actualized.

The waterfall strategy works well when project requirements are clear and the client and contracted developers share a clear and agreeable vision on the final product. The pros of this technique are its attention to detail, especially for huge projects that benefit from a clear, solo vision. For junior developers, the waterfall technique is also a good method to involve them in the project without overwhelming them with too much responsibility.

The burdens are that changes happen constantly. Regardless of whether the development group can construct precisely what the client initially needed (which doesn’t generally occur), the market, innovation, or the association may have changed so much that it is adequately pointless and an exercise in futility.

Waterfall works best as an application development technique when:

  • You don’t envision numerous progressions
  • Spending plans are fixed for the task
  • You’ve completed a comparative undertaking previously
  • The client is clear and doesn’t plan to be included much until the end

Rapid Application Development (RAD)

As you may expect, the waterfall technique does face some major issues. The development process usually takes a long time to arrive at a product, which means groups must be large enough to fulfil every requirement. Customer relations can also be strained when a client is discontented and the entire development needs to start over.

In this way, another technique called quick application development (RAD) rose, seeming almost the inverse of the waterfall strategy.

RAD depends on prototypes so that the client can access a working form of the app as from the start, which is later used throughout the progress of development. The application development group and the client work hand in hand throughout. RAD groups are kept small, usually made up of experienced engineers who are experienced and skilled in many disciplines. In case a project changes direction midway, the RAD team can still have the capacity to adapt effectively. The product gets increasingly refined after every stage, closer to the final product, even though the early prototype may look extremely rough.

RAD’s focal points are a fast and exceedingly adaptable group and an exceptionally cozy association with the client. In the event that changes are normal, RAD will almost certainly suit these a lot quicker than waterfall. RAD is likewise never excessively appended to a model and is continually eager to transform it to suit the necessities of the client.

In any case, RAD is certifiably not an ideal application development technique. RAD requires exceptionally talented (and generously compensated) developers to take a shot at an undertaking that may change in multifaceted nature constantly. There’s additionally less adherence to due dates and even more an emphasis on including highlights, which can broaden conveyance dates. RAD requires a great deal of contribution from clients who may not generally be accessible or comprehend what they need. Also, for certain applications, having a model isn’t valuable without seeing the whole item.

RAD is an extraordinary application development technique for:

  • An accomplished group of engineers
  • An exceptionally drawn in client
  • An adaptable conveyance date
  • Squeezing business


Agile share fundamental similarities with RAD, but incorporates a few additional features that make it more progressive and suited to bigger projects. Agile is iterative, yet centres around structure includes each one in turn. Each element is worked in an efficient manner in the group, however the client is included to see the highlights and approve them before the following component is created.

Agile runs, or set of time when a specific element ought to be constructed, tried, and displayed. It attempts to join the whole SDLC for a component into each run. This, in a perfect world, adheres to an arranged timetable, yet in addition, take into account visit surveys.

Agile doesn’t concentrate on models, however just shows finished work after the run is finished. So while the client is educated more regularly than waterfall, the client just ever observes completed work, in contrast to RAD.

Agile is additionally more group or squad based. With RAD, you are working legitimately with a developer. With Agile, the application development group will likewise incorporate analyzers, UX designers, specialized scholars, and numerous others.

Agile is an incredible application development methodology when:

  • The undertaking is sufficiently vast to separate into a few runs
  • You have a ton of masters who can chip away at a group together
  • The greater part of the undertaking is known early and can be arranged out
  • You have great task pioneers set up


The Right Developer = Right Methodology

There are many components that affect the finishing product. As a client, you need to think about your requirements and expectations measure of the project, do not hesitate to raise queries and request for changes, understand the roles of your developers and designers, work with a feasible timeline.

It is key for you to decide on an app development studio that suits your project and vision. This means checking their expertise, initiating meetings and communicating your visions clearly with them, to make sure that what they can provide is appropriate for your project. While there are many top app development studios in Singapore rising, do keep in mind that the most expensive studio does not mean that its the best quality, so make sure to do your due diligence before you decide so that you don’t waste both time and effort!
