In the Theory of Constraints methodology a  “Jonah” is a consultant that employs a systematic and logical process that is a practical blend of the scientific method and the Socratic technique to answer the three questions essential to any successful change: What to Change?, What to Change To? and How to Cause a Change? This process is referred to as the Theory of Constraints (TOC) Thinking Processes (TP). Jonah refers to individuals who have gained a working knowledge of the TOC TP upon completion of The Goldratt Institute’s

Jonah SM Program. (
