Simulation 1
• Build Lego Houses!• 4 rounds of 30 seconds each• Push to build as many houses as possible• STOP and count inventory on your table• @end draw a card = market demand

7 Wastes of Manufacturing
• Unnecessary Transportation• Inventory (WIP)• Motion• Waiting• Overprocessing• Overproduction• Defects

Push and Pull Systems
Customer Demand
Build “just-in-time” Adapt
Pull system (Simulation 2)
Anticipate Demand
Build “just-in-case”
Focus on utilization
Push system (Simulation 1)

Kanban
Build 10 doors

Examples of Pull systems with signals

Simulation 2: “Pull”
• 4 rounds of 30 seconds each• @start draw a card• Empty space is your signal to produce• STOP and count inventory on your table

Lean @HootSuite
• Unnecessary Transportation? Kickoffs• Inventory? Partially Completed Work? Kanban: Small
Batch Sizes• Motion? One thing at a time• Waiting? GoSee + autonomy + WIP limits• Overprocessing? Gold Plating? Done is better than
perfect• Overproduction? Extra Features Kanban: WIP limits• Defects? Automated testing + design reviews
Continuous Improvement + Respect for people
