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 interaction 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 .

Principal #1: Individuals and interaction over processes and tools

Principal #2: Working Software over Comprehensive Documentation Requirements Gathering Use Cases / Scenarios Functional Specs Design Specs Code Integrate Test Fix User Stories / Project Plan Iteration 1 Iteration 2 Iteration 3 Iteration 4 Design / Code / Test Stories for Next Iteration

Principal #3: Customer collaboration over contract negotiation

Principal #4: Responding to change over following a plan

Total Transparency At any time the status of the project is visible for everybody
