There is one real parameter when creating a Takt plan. Do not overburden the system. If more crews are needed, make sure the market has them. If materials are needed at expedited rate, make sure supply chain can accommodate. Research drawings before going to software. Builders who go straight to drawings are different from builders who go straight to software. The latter method puts things in the wrong order. Preliminary Takt zones in Phoenix for hospital space start at 10,000 square feet. Eventually they reduce to 3,000 to 7,000 square feet. Preliminary Takt time is usually 3, 5, 7, or 10 days. Five is most common because it represents one work week. Little's Law shows the power of smaller zones. Five floors with 5-day Takt equals 45 days total. Same project with 1-day Takt equals 29 days.

What you'll learn in this episode:

• Why drawings come before software: builders visualize flow, see constraints, identify preliminary zones
• Phoenix throughput rates: 10,000 square feet every 5 to 7 days, total process time 7.5 to 9 months
• Little's Law optimization: 1-day Takt finishes in 53 percent of the time compared to 5-day Takt
• The 15 Jason and Spencer rules: remove roadblocks daily is first priority, equal zones, deliveries on time or turned away, trades work weekends if not done
• Why Takt handles changes better: stabilizes entire project so changes can be isolated and focused on with Last Planner or Scrum

The difference with Takt is it is all downhill from here, whereas with CPM your nightmare is just beginning.
