I've always used the word "Agile" to describe a project management style that can move quickly and respond to change.

Becoming a certified scrum master and rigidly following the rules of SCRUM seems counter to this. Isn't the first line of the manifesto "Individuals and interactions over processes and tools"

Having said this, I should add that I believe even agile teams require strong leaders with a clear vision for the product, I'm not a fan of democratic software development.
