- Revolution: sweep away and replace
- Evolution: copy; differentiate; select; amplify; repeat
Perhaps a discussion for another time is how this relates to politics and management, and why it is that many politicians/managers (even conservative ones) favour revolutionary changes - that they can take credit for? - over evolutionary changes, which necessarily require competition between ideas and failure of quite good ones, so that better ideas are amplified.
The mechanism of evolutionary change can be seen again and again in agile methods. I''ve written elsewhere about its relevance to the evolution of processes in Kanban (see "Evolution and the culture of an adaptive organisation"). Here's another example from a test driven process: the "test-change-test-change-test" cycle in BDD and TDD-like approaches.
