Thinking processes (theory of constraints)
Thinking processes in Eliyahu M. Goldratt's theory of constraints, are the five methods to enable the focused improvement of any cognitive system (especially business system).
Purpose
The purpose of the thinking processes is to help answer questions essential to achieving focused improvement:
What to change?
What to change it into?
How to cause the change?
Sometimes two other questions are considered as well:
Why Change?
and:
How to maintain the process of ongoing improvement (POOGI)?
A more thorough rationale is presented in What is this thing called Theory of Constraints and how should it be implemented.
A more thorough work, mapping the use and evolution of the Thinking Processes, was conducted by Mabin et al.
Processes
The primary thinking processes, as codified by Goldratt and others:
Current reality tree (CRT, similar to the current state map used by many organizations) — evaluates the network of cause-effect relations between the undesirable effects (UDE's, also known as gap elements) and helps to pinpoint the root cause(s) of most of the undesirable effects.
