I'm currently listening to David Snowden talking about complex adaptive systems (a team producing software counts).
In Agile software coaching and project management, I've heard that one of the useful ways to get a team to change is to have a sense of urgency to which the team needs to respond, or to create one. The theory is that this will allow the team to self-organise around the sense of urgency.
In real life, if there's a crisis, someone often takes control and is quite forceful about holding that control until the crisis has passed. This is also the recommendation which I believe David Snowden makes.
Is there a difference between the way a PM and team should act in a real crisis from a crisis generated in order to drive change? Is it useful to create or fake crises for the purposes of change, or should we be waiting until there's genuine need? In either event - what's the best way to help a team work within a crisis situation?
