Discussion between rounds:Difficulties with the system
Management Team: What did you feel during the game? Were you busy? Did you manage to implement your plan? Were you in control?
Drywall team: Were you busy?
HVAC team Were you busy?
Bottleneck, Cycle time, WIP, Push What is the meaning of cycle time for apartment
construction in real projects? How would you improve the process?
