Agile Manifesto

"We are uncovering better ways of developing software by doing it and helping others do it.

Through this work we have come to value:

 

                                               We Value :                                                           Over : 

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.”
