There is a definite gap between those who are using the word agile and those who actually understand the agile project management methodology. Agile is often used as an excuse to not write any project documentation, to work chaotically, to be unorganised!
My plea to the evangelistic arm of the agile fraternity would be “curb your enthusiasm”. Seek to integrate the ideas of agile with everything that already works, present it as another string to the project manager’s bow and not something that will sweep all before it in a grand revolution.
That’s the secret to embedding all that is good about agile in the professional culture of project management.
