How risky is engagement?

Until leaders learn how to facilitate engagement well, there is a logical hesitancy about it. We have all seen committees run amok, convincing others they have become dumber together in pursuit of compromising consensus, 

It's all about the design of the process. Not every group process is effective. Even a group of smart people with a bad process will not turn out a timely, effective outcome. 

The most salient characteristic of a good process is engaging people in generating, growing and prioritizing their questions about the past, present and future so they learn their way into an effective approach.
