the agile methodology, in the form of a topic on extreme programming
from agile guru Kent Beck, has gained a cult following as a management
bible for its simple leadership ideas.
The Agile Manifesto (http://agilemanifesto.org/) states:
We are uncovering better ways of developing software by doing it and help-

over comprehensive documentation
Customer collaboration
over contract negotiation
Responding to change
over following a plan
The Agile Manifesto is based on 12 principles:
1. Customer satisfaction by rapid delivery of useful software
2. Welcome changing requirements, even late in development
3. Deliver working software frequently (weeks rather than months)
