Just-in-Time
Flow synchronization and load discipline
What Just-in-Time requires in practice
Trigger work by actual demand, not by availability. Respect capacity limits. Deliver information when it can be used. Ensure handoffs occur when the receiver is ready. Make delays visible rather than hidden in queues.
Just-in-Time is not about working faster — it is about working at the right moment.
How ASOW supports it structurally
- Defined process states and readiness criteria
- Visibility of work queues and bottlenecks
- Clear ownership of handoffs and approvals
- Alignment between planning and execution
- Traceable delays and waiting reasons
Typical ASOW instruments
- Document approval workflow: Reviews triggered by readiness, not by pressure
- Audit planning and scheduling: Timing aligned with resource availability
- Risk treatment action tracking: Work begins when resources are committed
- Change implementation gates: Changes activated when downstream processes are prepared
Just-in-Time reduces pressure by preventing overload, not by accelerating work.
When this approach fits
Good fit when: Work flows across multiple roles or teams, bottlenecks and waiting cause delays, overcommitment leads to quality loss
May be unnecessary: Work is urgent and unpredictable by nature, capacity is abundant and stable, delay has no negative consequence
