Processes built like this work fine, until they start to grow, and when we discover that processes in one hierarchy want to use ones from elsewhere. Then it looks less neat. And turf wars start to decide who ‘owns’ the common processes.
This so popular that the different levels in the process hierarchy get given names: you’ll hear consultants talk about “Level 1 Processes”, or even Level 0 (which are usually something crazy like ‘Run the Business’), so this idea of hierarchy has lots of friends.
But it’s an illusion.
There is no ‘run the business’ process: it has none of the characteristics of the process (start, end, owner, metrics) – it’s just there to make the PowerPoint slides look neat.
