Waterfall vs Agile

Posted by iammarchhare on 21 July 2009

I frequently like to compare waterfall and Agile methodologies, or perhaps mindsets would be a better term.  Yet, I realize that my descriptions are colored a lot by my own experiences.  So, I do like to point you to other sources from time to time that take a different approach or describe the differences in other terms.  I hope that gives the reader a more well-rounded look at things.

Robert Merrill on 18 February 2009 posted “A Tale of two processes”.  He starts out describing “How to create software” by writing:

Let’s create some software value. It’s very simple.

  • You tell the programmers what you want the software to do
  • They create it
  • You verify that it does what it’s supposed to
  • You let people start using it, and out pours the value.

Sounds simple, right?  Well, in a nutshell, he has summed up how waterfall is supposed to work.

I think the contrast is interesting and a worthwhile read.  You can read his article here.
