An endorsement of a software development methodology has always been recognized as a useful and helpful framework that helps the project team structure, plan and control the development of IT Processes, Products and Services.

What is Agile?

Agile methodology is a project management framework used by teams to iteratively and incrementally complete tasks and projects. Mostly agile is implemented in the form of a working framework known as scrum, over short work beats called sprints.

Agile methodology is a convention that helps uninterrupted iteration of development and testing in the software development process. In the Agile model, development and testing activities coexist and this allows more communication between customers, developers, managers, and testers.

What is the Waterfall methodology?

The Waterfall Model is succeeded in the sequential order, and the development team moves to the next phase of development only if the previous step is completed successfully.

Advantages of the Waterfall Model:

  • The waterfall model is easiest to manage and each phase has specific deliverables and a review process.
  • Suitable for smaller size projects where requirements are easily understandable.
  • Helps in the Fast delivery of the project
  • The process and results in the waterfall model are well documented.
  • Easily compliant method for shifting teams
  • Favorable to manage dependencies.

Advantages of the Agile Model:

  • It is a focused client process and the client is frequently involved during every stage.
  • Provide a better result from the development projects.
  • Assures the quality of the development.
  • The client and team know what is complete and what is not and therefore reduces the risk in the development process.

Limitations of the Waterfall Model:

  • Not optimal for a large size project
  • A less effective method if requirements are not clear in the beginning.
  • Changes are hard to implement in the previous phase.
  • The testing process starts once development is over and it makes it difficult to fix bugs found later in development.

Limitations of the Agile Model

  • It is not a useful method for small development projects.
  • Important decisions are required to be taken by Experts.
  • Higher Cost of implementation.
  • The project can easily go off track if the project manager is not clear about the outcome he/she wants

Key Differemce

  • Agile methodology is known for its flexibility while Waterfall is a structured software development methodology.
  • Agile chases an incremental approach while the Waterfall methodology is a sequential design process.
  • Agile percolate testing concurrently with software development whereas in Waterfall methodology testing comes after the “Build” phase.
  • Agile allows changes in requirement while Waterfall has no scope of changing the requirements once the project development starts.
