Just finished a 3-day hosting gig in Shediac, NB. And, just saw "An Inconvenient Truth". The parallel here is quite simple really.
In the flick, Gore shows an animation of boiling a frog. Essentially, he says that if you plunge a frog in boiling water, it jumps out. However, if you plunge a frog in water that is room temperature - and then boil it - the frog will stay, eventually boiling to death.
And so it is with organizations.
As cultures stagnate, disillusionment creeps in. Gradually. Seems harmless enough at first. After a while, it becomes "the way things are done around here". Then, it becomes the thing or things you can't change or that "we've talked about for years".
Nobody in the room would choose the organization 'as is' in their vision of what it 'could be'. They've just been warmed gradually enough that they can't feel the boil.
