Obvious or not true after all?

Obvious or not true after all?

I was reading over this summary of the organic-mechanistic typology of Burns and Stalker, and at first sight it seems simple and logical: the best way to organize a company is contingent upon its environment in the following way:
If the environment of the firms is stable, go for the mechanistic organization type.
If the environment is changing (quickly), the organic organization form is preferable.
HOWEVER, assuming we all live in a fast-changing world (who would disagree with that), how come that we still find so many mechanistic organizations??? Maybe there's more to it than Burns and Stalker thought... I wonder what?

	Resistance to Change Countering Burns and Stalker's observation is the natural tendency of systems and those within them to resist change. Incumbents tend to hold onto outmoded structures, processes and methods well past their prime and suitability for a host of understandable yet unhelpful reasons.
