Waterfall Vs Agile Model

10 Mar

Differences between the Waterfall Model and Agile Model:

  1. The main advantage is the backward scalability in Agile. Under waterfall approach we cannot change the decisions and implementations that we had made under the previous stages. If we want to make changes under waterfall we will have to build the entire project from the scratch once again.
  2. The flexibility to error check under any part of the development stage makes Agile more bug free and less mistaken as compared to Waterfall which can only test bugs at the end of the development module.
  3. Since Agile provides flexibility to make changes as per customer requirements it is more inclined towards better client satisfaction. This is a real set back for the Waterfall model which doesn’t allow any modifications once the module has been completed.
  4. Under Agile development modular partitioning of the software can be effectively carried out as compared to its counterpart. Though both of them allows option for segregation the later lacks the modifications in the implementation stage. The rules are set down before the commencement of the project hence it hinders further break down of the logical module. Whereas Agile can be of great help under such situations and can allow simultaneous development of different modules at the same time as per time bound requirement. If we want the project to be more segregated Agile comes as a pain relief for developers.
