Who is Alistair Cockburn?

Alistair Cockburn is one of the initiators of the agile movement in software development, helping write the Manifesto for Agile Software Development in 2001, the agile PM Declaration of Interdependence in 2005, and co-founding the International Consortium for Agile in 2009. He is a principal expositor of the use case for documenting business processes and behavioral requirements for software, and inventor of the Cockburn Scale for categorizing software projects.

The methodologies in the Crystal family, described by Alistair Cockburn, are considered examples of lightweight methodology. The Crystal family is colour-coded to signify the "weight" of methodology needed. Thus, a large project which has consequences that involve risk to human life would use the Crystal Sapphire or Crystal Diamond methods. A small project might use Crystal Clear, Crystal Yellow or Crystal Orange.

Cockburn received his PhD degree from the University of Oslo in 2003.
