Agile is Pragmatic Approach to Project Management, is waterfall dead completely ?

Agile is not a project management approach. We make this mistake a lot, so let me repeat: Agile is not a project management methodology. It's a cultural model, and project management must adapt if your organization is Agile. What we call "Agile" predates software development and has close relations with Lean, so it can be used successfully in other industries. The Agile Manifesto, which specifically addresses software development, is a set of values and principles, but it does not define a method for developing software or managing projects.

When you understand that, the waterfall question does not follow. A predictive lifecycle ("Waterfall") can still be used in an Agile environment, and in many cases it should be used. What you cannot do is micromanage your team in an Agile environment, nor can you drive your plan to completion while ignoring changes that should be considered. (This should be true whether your organization is Agile or not.)

The choice between plan-driven approaches or change-driven approaches is a false dichotomy, because each is relevant in the proper context.

Well stated, Wade. You will make Sergio proud.
