I read an interesting post on organizational change management by Biju Bhaskar.. adding my 2c..
Many a times, while implementing organizational changes, we overlook the role of cynics. To me, having a cynic (who is equally passionate against the change) in the team helps in the following ways:
1. you get advanced warning on possible failure points
2. You get real time results on the change management process (i.e if you can help the cynic understand the merits of the change during the process..then you are on right track)
But then, the key is to create a conducive environment where even the cyncis 'dare' to stand-up for whatever they believe in. I would rather have bunch of highly opinionated people against the change, over having a set of people who don't have an opinion at all.
