Procedure
a. Preparation
• Have a chronometer for time measurements
• Have a flipchart and post-its to track results during each iteration and include key notes during the simulation
• Have the tools over a table
b. Initial setup

Rules of the simulation
d. Allocate roles to participantsThe simulation must have at least 3 participants with the following
functions:
e. Define goals for each step (iterations)In the end of each iteration the group creates suggestions for improvement and evaluation of the cost/benefit.
• 1 operator
• 1 quality controller
• 1 material handler
• 1 time keeper/flip chart person
• 1 video recording
