The Agile Manifesto says that agile developers value:
Individuals and interactions over processes and tools.
Working software over comprehensive documentation.
Customer collaboration over contract negotiation.
Responding to change over following a plan.
This is quite different than (the opposite of?) traditional project management. Both approaches bring an interesting perspective to the table, but in my experience, neither one will work 100% of the time. Make your own methodology - the one that works for you!
