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. http://agilemanifesto.org/ 

Individuals and Interactions

Customer Collaboration 

Responding to Change 

“A fanatic is one who redoubles his effort when he has forgotten his aim.” George Santayana 

“The real goal of the methodologies is to sell books, not to actually solve anybody's problem.” Joel Spolsky

As aspiring Software Craftsmen we are raising the bar of professional software development by practicing it and helping others learn the craft. Through this work we have come to value: • Not only working software, but also well- crafted software • Not only responding to change, but also steadily adding value • Not only individuals and interactions, but also a community of professionals • Not only customer collaboration, but also productive partnerships That is, in pursuit of the items on the left we have found the items on the right to be indispensable. 

Well-crafted Software 

Steadily Adding Value 

A Community of Professionals 

Productive Partnerships
