Key takeaway
- A plant's real constraint is the time between a signal and the right action. What to measure, who owns it, and a five-step plan to cut decision latency.
What is decision latency in manufacturing? It is the elapsed time between a signal arriving and the right action being taken on it. A plant's real constraint is not capacity, capital or data. Thirty years of automation and ERP compressed execution time by orders of magnitude, while decision time barely moved, because it still runs through a small number of people who are each doing three other things. The fix starts with measuring that time, then encoding the knowledge and granting bounded authority one decision class at a time.
The 60-second brief
- The real constraint: not capacity, capital or data, but the elapsed time between a signal arriving and the right action being taken on it.
- Why it persists: automation and ERP compressed execution time. Decision time barely moved.
- The tell: six problems you report separately (overproduction, idle capacity, NPD cost, scrap, flat aftermarket, skills shortage) are one condition.
- The plan: measure latency, fix master data, encode exceptions, observe then recommend, then grant bounded authority one decision class at a time.
- The one number: hours between signal and correct action. Measured, not targeted.
Your Constraint Is Decision Time
This is about what to measure, who owns it, and in what order, written for people who have to assign this to someone on Monday.
Every inefficiency below is downstream of the gap between signal and action. Nobody measures it. That is the opportunity.
What Is Decision Latency Costing You Right Now?
Six problems your operation already reports separately. They are one condition:
| Problem | Underlying cause |
|---|---|
| Overproduction | The decision cycle is slower than the demand cycle. Batch size is a hedge against the cost of replanning, not a manufacturing choice. |
| Idle capacity | No shared context across firm boundaries. Unfillable orders and unused machines coexist in one cluster and never meet. |
| Rising NPD cost | No shared representation of the product across design, supply and manufacturing, so every handoff is re-specified. |
| Scrap and rework | Detection is decoupled from correction. Inspection is a scheduled event rather than a continuous inference. |
| Flat aftermarket | No persistent record of what shipped, to whom, in what configuration, so your highest-margin revenue is unreachable. |
| Skills shortage | Operating knowledge lives in a few heads and is never encoded, so decision capacity cannot be scaled by hiring. |
Why Doesn't Your Current Stack Close the Gap?
A system of record answers what happened. An analytics layer answers what happened and why. Neither answers what should happen next, given every live constraint, and then acts. That last step stayed human. So every system you added made more information available and left the bottleneck where it was. In several plants it moved the bottleneck: you now produce more reports than anyone has time to read.
Apply one test to any AI proposal: does it shorten the time to a correct action, or does it only improve the report a person still has to act on? Only the first changes your P&L. The layer that does this is decision infrastructure.
Target Points, with Named Owners
Assign each to a named owner. Review the measurable, not the initiative:
| Owner | Target | Measure |
|---|---|---|
| COO or plant head | Signal-to-action time on recurring shop-floor decisions | Median hours across five decision classes |
| Supply chain | Decision latency of tier-one and tier-two suppliers, on the scorecard next to financial and concentration risk | Response time to an expedite or engineering change |
| Quality | Move inspection toward continuous inference on the three highest-scrap lines | Detection-to-containment hours |
| CIO | Agent-readiness of the core stack: APIs, events, permissions, master data, externalised rules, audit | Six of six checks passing |
| CFO | Inventory and expedite spend held to absorb decision delay | Annualised cost of latency |
| CEO | Whether encoded operating knowledge is treated as an asset with an owner or as an IT project | Exceptions documented versus tacit |
The Plan, in Order
Each step has an exit test. Do not start the next one until it passes.
- Weeks 1–2: measure decision latency. Pick five recurring decision classes: a schedule change, a material substitution, a quality-hold release, a supplier expedite, a customer date commitment. Timestamp the signal and the action. Exit: five numbers on one page that leadership agrees are real.
- Quarter 1: make master data canonical. One supplier, one identity; one part number, one meaning. Any system reasoning over three spellings of the same vendor produces confident nonsense. Exit: duplicate rate below 1% on suppliers, parts and customers.
- Quarters 1–2: encode your top twenty exceptions. Non-standard customer lead times, approved material substitutions, work centres that cannot be interrupted mid-batch. This pays for itself even without an agent, and insures you against the next retirement. Exit: a new planner makes a correct call without asking the veteran.
- Quarters 2–3: run one decision class, observe then recommend. Choose something frequent, reversible and low-value, such as standard replenishment. The system proposes, a person approves, you count agreement. Exit: approval rate sustained above roughly 90%.
- Quarters 3–4: grant bounded authority, one class at a time. An explicit envelope of decision class, value limits, hours and reversibility; everything outside it escalates. Authority is granted per decision class, never per system. Exit: latency on that class down by an order of magnitude, with no unreviewed exceptions.
Six Questions for Your Next ERP Conversation
Upgrade, renewal or replacement: these six questions are the requirements list. Buy for reporting and you will be back here in three years.
- API surface. Not a screen or a nightly batch file. Nothing can act inside your cycle time through a form.
- Event stream. Stock movements, quality holds and date changes publish events rather than waiting to be noticed.
- Granular permissions. Roles can express "may release POs under a set value, may not approve first articles".
- Canonical master data. One identity per supplier, part and customer, enforced rather than aspirational.
- Externalised logic. Business rules exist as data, not buried in screen validations and customisations.
- Actor-aware audit. The log shows which agent acted, under whose authority. Non-negotiable in a regulated plant.
What Not to Do
- Do not re-platform first. An integration and event layer over the ERP you already run usually beats eighteen months of migration. Modernise the interface to your ERP before you modernise the ERP.
- Do not start with the highest-value decision. Start with one you can afford to be wrong about. The first deployment calibrates trust; it does not capture value.
- Do not delegate what cannot be undone. Anything irreversible within cycle time keeps a person in the loop permanently, not as a transitional measure.
- Do not delegate accountability. Safety, regulatory and personnel decisions stay with people. Accountability for them is not transferable.
The One Number
You cannot hire your way out of a structural skills shortage. You can encode the operating knowledge of the business so that a 60-person firm has the decision throughput of a 200-person one. That is the real economic case, not any claim about individual task productivity. Ask this in your next operations review:
How long, in hours, between a signal arriving and the right action being taken on it?
Not the target. The measured number. If nobody in the room can answer, you have found the first thing to fix, and it costs two weeks of attention, not a capital budget.

Frequently Asked Questions
Why is decision time the constraint and not capacity?
Execution has been automated for decades, but deciding what to do next still passes through a few experienced people. Overproduction, idle capacity, scrap and expedite costs all trace back to that delay.
How do you measure decision latency?
Pick five recurring decision classes, such as a schedule change or a supplier expedite, and timestamp when the signal arrived and when the correct action was taken. Report the median hours for each.
Should a plant replace its ERP to reduce decision latency?
Not first. An integration and event layer over the existing ERP usually delivers more than a long migration. Modernise the interface before the system.
Which decision should be automated first?
One that is frequent, reversible and low-value, such as standard replenishment. The first deployment builds trust; it is not where the largest value is captured.
Which decisions should stay with people?
Anything irreversible within cycle time, and safety, regulatory and personnel decisions. Accountability for those is not transferable.
