Collaboration is a basic Agile principle and universally seen as a net positive. Yet few teams experience true collaboration, with the reasons and remedies not always clear. In this presentation I share my nonscientific analysis of nine sequentially operating prerequisites for any group people to collaborate in a given situation. As well, I describe six environmental and system cues and pressures that discourage people from collaboration even when all the prerequisites apply. I close with a process you can use to increase collaboration in your team.
