Application or Software Development is a very tedious and rigorous process. Based on which software life cycle model you choose to develop your application, you will encounter various phases of development. The various models in use these days include the RAD (Rapid Application Development) Model, Waterfall Model and Prototype Model to name a few. But whatever model you choose, the main three phases in the application development phase will remain the same and even if a model does not specify these phases, it is recommended to go through these phases in order to obtain the best result.
The Most Important 3 Phases
Well, the hyped important phases are as described below. I have tried to include relevant examples wherever possible, using which I understood these phases. I hope you understand the importance of these phases and pass on the knowledge to others!
- Requirements and Planning: The first phase is the requirements and planning phase, where you gather the requirements from the customer and then make a plan on how to complete those requirements. I would say that this is the most important phase because if you gather the requirements correctly, it is a really good thing for you to work upon. Take for example that if you were asked to make an application for a company. The company wants you to make a pay roll application for them. Now, if they just tell you this much it is difficult for you to determine the actual requirements of the company. But if you force the company to tell you more and more about the project, as in what are they expecting it to be, it would be very easy for you to build that application.
- Design and Implementation: The next part is of course the designing and implementation part. In this part, do all the UI designing for the application first and once the UI is ready, get ready to put in the actual code for that application. When coding the application, keep in mind the various tips for creating a successful application by minimizing the use of variables wherever possible and also by re-using the code if possible.
- Testing: The last phase is the testing phase. When you develop an application, the testing phase is a pretty lengthy one, though it might not feel like at this moment, but it will be a lengthy one when you come to it. In the testing phase, you need to check the application you built for every possible type of input and operation. If you find any error, it is necessary to go back to the previous phase and fix it as soon as possible. Now, after fixing that error, make sure to go through the entire testing phase again because sometimes fixing an error creates another error in some other part of the code.
After reading this article, I am pretty sure you will be able to develop applications in a better and an easy way.
