Improvisation is a pure form of collaboration. Because of that, improv has a great set of tools to learn the skills you need to work with a team when ambiguity abounds. Unlike work it's afun and engaging pursuit and provides a great training ground for teamwork.
So, how do you get your organization to embrace this new mindset?
Start at the top
Culture change only works when the everyone is in. Teams can benefit from spot interventions and work better together, when it's supported from the top its happens more easily. For example, when you look at how the board and executives feel about fiscal policy, professional development, or any aspect of a business you will see that reflected through every part of the organization. Get the executive team going on improv along with everyone else.
Integrate Applied Improv Into Learning and Development
Applied Improvisation is a well established corporate consulting discipline that uses the lessons of performance improv (yes, like the television show "Who's line is it anyway?") The main difference is that there are specific learning objectives and every exercise gives an opportunity to debrief with the group to draw the lessons from them. If you are working with someone who just plays games and moves on, find someone else.

Encourage employees to start improv clubs, troupes, or sponsor classes
The lessons of improv are easily available to anyone who takes a class and learns it for performance. The truth is that exposure to improv helps people in myriad ways - confidence, public speaking, thinking on their feet, better communication... but that's another post.
