The 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 systems). 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?
- 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. (Goldratt, Eliyahu M. (1990). What is this thing called Theory of Constraints and how should it be implemented. [Croton-on-Hudson, NY]: North River Press. p. 161. ISBN 0-88427-166-8)
