Wide Comparison of Agile Model with Waterfall Methodology

    

Agile Vs Waterfall Methodology

Do you know how effectively the adoption of Agile in projects is delivering products with early ROI? Certainly! Software professionals may have innumerable advantages when they adopt the Agile software development instead of considering other Waterfall model. According to my opinion, while comparing Agile with the Waterfall methodology, agile principles and practices would always produce an unusual product.

In recent days, Agile methodologies have greatly ploughed its ground in the software development projects because of its huge reputation among the project managers who are implementing Agile in their projects.

Agile Vs. Waterfall Methodology:

• Changes and alterations are adapted at the end of each stage in Agile methods and more importantly there is no necessity rewriting the entire program. Whereas, it is hard to change the software which is designed and implemented according to the user needs in the Waterfall method. It can be fixed by returning back to the source and need to design it by new system. Overall this method is inefficient and very costly.
• Since the changes can be made after the initial planning in Agile methodology, it will be easier to add the new features with up to date with the latest developments.
• Unlike the traditional waterfall approach, the agile development method is based on incremental and iterative development. The agile model does not build a complete system at once in software development, but rather it develops incrementally.
• Time consumption in upfront for documenting requirements, since the development is done incrementally.
• In the Agile model, customer feedback will occur simultaneously with software development at the end of each sprint in order to evaluate the project prioritization, whereas in the waterfall approach will perform all testing after the completion of the project.
• Since the testing is done at the end of each sprint, the bugs are rectified at the time of test in Agile model. Hence there won’t be any bugs at the end of the project. Whereas in Waterfall model, as the whole product is only tested at the end, the bugs will affect the whole product.
• Customer satisfaction will happen rapidly, continuous delivery of useful software in agile approach.

Concluding this dilemma by referring the project managers or the leaders of a team in SDLC can adopt agile approach to their project by means of project management course. Rebus Business solutions will guide on this to acquire the courses like CSM, PMI-ACP, PMI-PMP and more.
