Radical change
Radical approach to change is like pushing a rock off a cliff. It is the fastest way to get the rock down to the base of the mountain. But it is more costly. On its way down, the rock could hang on the mountain, fall into a dish, or scratch the surface of the mountain or itself. And it could crush lives as it lands on the ground.
The approach is the fastest way to make immediate impression, and announce ones presence. But it may create many new vacuums that might never be filled.
Do not use this approach to solve long-term or endemic problems.
But if it is containing a short-term problem, like a virus, for example, to prevent a spread, radical change is best—as well as if you want to create immediate impression, or stamp your presence in a place or against your opponent. But have a plan to fill the new vacuums the change would create.
Radical change may win the short war, but never the long war. It will be immediately replaced by the old or another new trend as soon as its leader leaves or dies, or it will face stiff opposition from competitors.
