AgileWe are uncovering better ways of developingsoftware by doing it and helping others do it.
Through this work we have come to value:
The Agile ManifestoIndividuals 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.
