a number of problems with the traditional waterfall model was making it seem redundant. in this software development process, there is a steady flow from one phase into the other. it is known as the traditional or pure waterfall model. how is it different from the traditional design? get in touch with us and we’ll talk… the waterfall model came into software development from the manufacturing and construction industries. in this model, there are different phases the software goes through. however, once the software has progressed from one phase to the next stage, there is no way the software can go back to the previous stage. this model in software engineering came into existence because of the defects in the traditional design.
at the same time, a number of tasks can function concurrently, which ensures that the defects in the software are removed in the development stage itself and the overhead cost of making changes to the software before implementation is saved. the diagram of this model does not differ from the traditional waterfall model diagram, as to every phase of the model a verification and validation step has been added. the other advantage is that it is a more relaxed approach to formal procedures, documents, and reviews. it indeed does lend flexibility to the software development process, but tracking the progress on all the stages becomes difficult, as a number of phases are underway at the same time. this dependency adds to the problem and the project can become a complicated at times. the development team may be tempted to move back and forth between the stages for fine tuning. in spite of the drawbacks, this model is extensively used in the software industries. in the article below,… an osi model is an abstract description of the working of various layers of a network.
