As these days I am writing about Scrum which is one of the agile methodologies, I though it could be nice if I can also list the other popular software development methodologies.

I have listed all these and also linked them to wiki as it has one of the very good definitions and details about every agile methodology.

Once I am done with the Scrum series I will touch the other ones. Hope this helps!
