This game is geared to show the importance of limiting the work in progress and to explore the following formula (implied by Little’s Law)
Flow Time = WIP/Throughput
- Flow Time (Cycle Time, Lead Time) – average amount of time it takes to fully complete a unit of work
- WIP (Work In Process) – is the average amount of units in the system
- Throughput – average number of units being completed within a given time frame
The game is designed to work with 6 to 12 people – we had 8 players and 1 facilitator
The team divides into the following roles:
- 1 – Customer
- 5 – Workers
- The rest are efficiency experts
We had a total of 8 players (6 workers, 2 efficiency experts).
The team organises themselves around a table. The image below shows how our team arranged themselves. Each worker has an empty area on the table directly in from of them referred to as a workspace.
