Create a Push$-$Pull Game$/$Simulation that can be demonstrated in $30-40$ min. This game will have $3$ phases:

Phase $1($Push$)$: Come up with a set of $4-6$ tasks where one task is intentionally harder$/$longer than the others. This will show how the inventory will build up quickly. Set a production goal. At some point once the simulation is going, measure how long it takes to get a part through the whole system, from beginning to end $($the part you are measuring Should follow through the queue of inventory properly. No jumping the line!$)$

Phase$2($Pull$)$: Introduce limits to WIP to reduce inventory in the system. No change to the steps each operator does. Introduced by only allowing a certain number of spots for inventory. If the spots are full, then upstream operator must not produce. The main focus in Phase $2$ is to show that Kanban helps reduce inventory but the line is still unbalanced and everyone will be waiting for the bottleneck operator. Establish at least $5$ KPIs $($key performance indicator$)$ to compare both push and pull runs. An example of KPI would be time efficiency, quality, accepted pieces, amount of WIP, throughput, average cycle time, etc.

Phase $3$: From phase $2,$ reorganize the tasks to achieve a balanced workflow. Incorporate work balancing strategies to enhance the overall cycle speed or reduce the number of operators.
