The Agile Manifesto states:
We are uncovering better ways of developing
software by doing it and helping others do it.
Through this work we have come to 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
That is, while there is value in the items on
the right, we value the items on the left more. source: agilemanifesto.org
