PDSA = HAMMER
PROBLEM SOLVING = SAW
PDSA is a method that drives forward by constructing new knowledge. It begins with theory. Corrective action is a problem solving method that a is reactive, rear view mirror process. The method begins with something deemed “wrong”.
The first is a method of discovery. The second is a method that tries to shove the world back into some box we have created.
These methods differ in aim, structure, and efficacy. Both methods have their place in a tool kit. A hammer is good for nailing things together. A saw is good for cutting things apart.
Confusing a hammer with a saw tends to mess things up.
