Here, participants will play three iterations of the match game (from "The Goal," by Eliyahu M. Goldratt). The exercise will demonstrate the importance of identifying the system constraint and the means to identify it. Once identified, the constraint can be used to minimize inventory and maximize return on investment. Real data from the audience are used to illustrate learning points and generate discussions. Analysis of the data includes a brief discussion of cost justifying a constraint reduction project. Prior knowledge of the game or the book is not required.
