Looking at the post title I remember my Software Engineering text book which had a diagram in blocks which was looked like a waterfall. What is this exactly? It’s one of the software development process in which you can see the progress flowing (water flowing) downwards through the different phases like “Requirements”, “Design”, “Implementation”, “Verification” & “Maintenance”.

There are many other models which are discovered by people but at last what I think is all the models in some or the other way convey the same message but with the different style of approach or process. The other models include Spiral/Iterative Development, Rapid Application Development which is also known as RAD, Agile Development, Scrum Development, V-Mode, Modified V-Model, CCMI, Test Driven Development, TMM & much more. I am not thorough with these models other than knowing few points about these. Some of these models are outdated but I see that still people in interviews ask these questions (I don’t know why, maybe they want interviewees to remember the great people who introduced these models to people“.

In Photo Gallery you can find the “Waterfall Model” in pictorial representation.

This post was written to update my knowledge about these models as well as helping others to understand little about the process models.

Thanks for your time.
