Agile Model Versus Waterfall Model

All the models derived at a given time to resolve a problem or to develop a system are based on some or the other logical approach. They offer a clear process to be followed to achieve the expected goal. Some models do have certain advantages which are not offered by others and they vary in terms of approach, analysis, development, testing and debugging.

Agile model certainly offers many advantages over waterfall model. The main reason for Agile model to have these advantages is, it is an evolved model from it’s predecessor (the Waterfall model), so it carried over all the advantages of the Waterfall model and in addition, a lot of the limitations or disadvantages from the Waterfall model were already addressed at it’s evolution and hence they became advantages instead in Agile model. This does not mean that Waterfall model is a failure, it was one of the first development models and it still offers a lot of potential to SDLC where a fixed set of requirements are to be followed and developed. The main difference, which could also come under Agile model’s advantage, is the backward scalability available in Agile model.

For a mobile application development, agile software development model offers tremendous opportunities and value to build dynamic applications in short cycles. The nature of mobile apps varies rapidly and Agile model offers quick return to short cycles and amendments as and when required. There are already some restrictions with mobile application development like, the size of the application, should be downloadable very fast, should apply updates quickly and smoothly and interact with backend server(s) seamlessly.

On the other hand, if the mobile application is not so dynamic and has a precise requirements and guidelines, Waterfall development model will be more efficient and can be used instead Agile development model. This scope of this paper is to cover briefly the major differences between the...
