The term came up during a discussion in the Federated Wiki room. matrix 
> Scrum and XP both asked, how should a team in a commercial environment make use of a "personal" computer, specifically, Smalltalk-80. When we became aware of another effort suspicious of long phases characteristic of "big design up front" we took that as validation but paid little attention to how they had come to their particular solution. When we did finally take a deep dive into each others work we focused on ideas we held in common and how to take those forward. Hence the agile manifesto. –– Ward
