Enter AgileEnter Agile

We have uncovered better ways of software development by doing it and helping others to 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”

Agility is the ability to both create and respond to change in order to profit in a turbulent business environment.
