Takt Rules of Flow
- Always maintain diagonal trade flow in a time by location format.
- Do not irresponsibly dissolve logic ties—use real data and adjust ties.
- Do not shorten durations without permission. Enable a shorter in zone cycle time with advanced design, pre-fabrication, delivery, logistics, and preparation.
- Do not trade stack or burden.
- Always work in One Process Flow [OPF].
- Always pre-kit work—don't start work unless it can be finished.
- Always use buffers in the production plan.
- Always have workable backlog for swing capacity.
- Never fix and freeze your plan to align with a baseline.
- Always analyze the Path of Critical Flow, not a critical path. A Path of Critical Flow will always have the activity, duration, logic tie, sequence, line of balance and a buffer.
- Always attempt to work the trades in a train going the same speed and appropriate distance apart.
- Flow by fixing problems—don't push trades to work faster.
- Always align Work In Progress [WIP] to capacity.
