A diagnostic starting point for manufacturers dealing with missed dates, expediting, and unreliable delivery.
Persistent lateness is almost never a single-cause problem. It's typically the combined effect of unstable flow, an overloaded schedule, and planning that reacts to yesterday's problems rather than controlling tomorrow's.
Unstable flow makes lead times unpredictable, so the same job can take very different amounts of time depending on what else is happening on the floor that week. An overloaded schedule compounds this - committing more work than the operation can reliably absorb guarantees that something will slip.
Planning friction is often the quiet multiplier: schedules that get rewritten daily, priorities that change without visibility to the floor, and a lack of trusted data on true capacity and lead time. Each of these erodes confidence in the plan, which pushes the business further into expediting and firefighting.
Fixing chronic lateness starts with stabilising flow and getting an honest, capacity-checked view of what the operation can actually deliver - then building a planning and control routine the whole business can trust.
