A PIECE FROM THE DAY JOB: Agile is a Thing of the Spirit.

Almost 20 years ago, the Agile Manifesto proposed a change in the way software is developed that values

• Individuals and interactions over processes and tools

• Working software over comprehensive documentation

• Customer collaboration over contract negotiation

• Responding to change over following a plan

Twenty years later, people still don’t understand how radical that was — including a lot of people who think they are practicing agile.
