The primary group cares concerning the coverage. They profit from it. They’ve organized themselves round it.
The second group cares about stability. They’ve restricted bandwidth, they usually’re not notably considering reconsidering all the things, on a regular basis.
The third group doesn’t care that a lot.
And the fourth group is harmed by the coverage, both instantly or not directly.
Change occurs slowly as a result of the primary three teams have energy, inertia and communications on their facet.
Change occurs when the fourth group can create the circumstances for the third group to care, after which these two teams transfer the urgency up the agenda.
It is senseless to argue with the primary group.
