Episode notes
Do Not Force Takt Planning Everywhere
- Pull planning works best when teams match the method to the work instead of forcing every activity into a takt format.
- Amenities, site work, and unusual foundations often need breakout schedules, while repetitive units benefit from visual takt planning.
Synchronize Takt And P6 Schedules
- Keep the visual takt plan and contractual P6 schedule synchronized through a standardized data structure.
- Callahan’s scheduler aligned rows, columns, and file formatting so monthly updates could move reliably between both systems.
Schedule Flow Can Conflict With Crew Incentives
- Flow planning can conflict with subcontractors’ incentives when crews vary in size or work faster than the sequence requires.
- Dan’s team sometimes accepted early work rather than wasting capacity, while avoiding unnecessary weekend work for more than a year.
