Manufacturers measure production output carefully.
They track completed work orders, machine utilisation, labour hours, scrap, yield and units produced. When a batch or production order is marked complete, the organisation records the output as manufactured.
But “made” does not always mean “available”.
The product may still require inspection, laboratory testing, document review, label approval, batch certification or final release. Until those steps are completed, the stock may remain in quarantine.
This creates a critical but often poorly measured period between production completion and commercial availability.
The product exists. The cost has been incurred. Demand may already be waiting. Yet the organisation cannot allocate, ship or invoice the stock.
That is the gap between made and shippable.
In many manufacturing businesses, this gap is treated as a quality-management issue. In reality, it affects working capital, customer service, production planning, warehouse performance and revenue recognition.
The longer the gap, the more finished inventory the company holds without being able to use it.
Production completion is not the end of the process
A manufacturing order may be physically complete while several operational conditions remain unresolved.
The finished product may be waiting for:
- Final inspection
- Dimensional checks
- Laboratory results
- Certificate review
- Batch record approval
- Quality assurance sign-off
- Packaging verification
- Label confirmation
- Deviation approval
- Non-conformance disposition
The production team sees completed output.
The warehouse sees quarantine stock.
Sales sees unavailable inventory.
Finance sees value tied up in finished goods.
The customer sees a delayed order.
These are not separate problems. They are different views of the same release bottleneck.
The issue becomes more serious when production, quality and inventory are managed in different systems. Completion may be recorded in the manufacturing system, inspection in the quality system and availability in the ERP, creating the testing bottleneck in manufacturing when critical information is spread across disconnected platforms.
The release then depends on a handover.
Someone must communicate the result. Someone must update the stock status. Someone must confirm that the inventory is now available.
Every manual step extends the time between making the product and earning revenue from it.
Why the delay is often invisible
Manufacturers usually measure lead time from order receipt to production completion or from order receipt to shipment.
The release period between those points may not have its own operational measure.
As a result, the company may know that an order shipped late without understanding how much of the delay occurred after production was already complete.
The business may blame capacity, labour, materials or scheduling. Yet the real bottleneck may be:
- Samples waiting to be collected
- Tests waiting for laboratory capacity
- Results waiting to be entered
- Records waiting for approval
- Passed batches waiting for ERP status updates
- Exceptions waiting for disposition
Because these activities cross quality and operations, no single department owns the full elapsed time.
Production has completed its task. Quality is processing the release. Warehouse cannot act. Customer service waits for an update.
The stock remains trapped between departmental measures.
This is why the cost is hidden. Each function can appear to be performing acceptably while the end-to-end process remains slow.
The working-capital impact
Finished goods in quarantine have consumed material, labour, machine capacity and overhead.
From an accounting perspective, value has moved into inventory. From a commercial perspective, the product may still be unusable.
A manufacturer producing £500,000 of finished goods each week may have a significant amount of capital waiting for release at any time.
If average release time is two days, the organisation carries roughly two days of production value in a restricted state. If release expands to five or seven days, the amount increases accordingly.
The cost is not only the inventory value.
The business may also:
- Use warehouse space for quarantined stock
- Produce replacement quantities because released stock is unavailable
- Expedite alternative materials
- Pay overtime to recover delayed orders
- Miss customer delivery windows
- Hold additional safety stock
- Delay invoicing and cash collection
A release delay therefore affects both sides of working capital.
Cash has already been spent to make the product, but customer cash cannot be collected because the product cannot ship.
The customer-service impact
Customers rarely distinguish between production delay and quality-release delay.
They ordered a product for an agreed date. Whether the item is waiting on a machine, in a laboratory or in a quarantine location, the commercial outcome is the same: it is not available.
The problem becomes worse when customer-facing teams cannot see the release status.
Sales may be told that production is complete and assume shipment is imminent.
Customer service may promise dispatch before final approval.
The warehouse may receive pressure to prepare the order even though the relevant batch remains blocked.
This creates internal friction and unreliable communication.
A customer would usually prefer an accurate explanation and a realistic delivery date over repeated promises that change.
To provide that accuracy, customer-facing teams need visibility beyond production completion. They need to know whether the exact stock behind the order is awaiting testing, under review, failed, approved or released.
The planning distortion
Production planning depends on a clear understanding of supply.
If finished goods exist physically but cannot yet be used, planners must decide how to represent them.
Counting quarantined stock as available may cause customer orders to be promised against inventory that cannot ship.
Excluding all quality-held stock may lead the planner to produce or purchase more than necessary.
The correct decision depends on context:
- Why is the stock held?
- What testing remains?
- When is the result expected?
- What is the historical pass rate?
- Is partial release possible?
- Is alternative stock available?
- Can the batch be reworked?
- Which customer demand is waiting?
When quality status is disconnected from planning, the system may treat every held item the same or ignore the hold entirely.
Planners compensate with spreadsheets, meetings and personal knowledge.
This weakens material planning because available supply is no longer a simple question of physical quantity. It becomes a question of quality state and expected release time.
The warehouse consequence
Quarantine is not only a system status. It is also a warehouse-control problem.
Held stock may need to be:
- Moved to a restricted location
- Clearly labelled
- Prevented from allocation
- Excluded from picking
- Protected from transfer
- Split by batch or lot
- Released in full or in part
- Routed to rework or disposal
When quality decisions are not reflected immediately in inventory control, physical and system status can diverge.
A batch may be marked as held in a quality application while remaining available in the warehouse system.
A batch may pass inspection but remain blocked in the ERP.
Warehouse staff then rely on emails, labels, verbal instructions or manual checking.
The risk is obvious: held material may be shipped, or passed material may remain unused.
Both outcomes are expensive.
Why adding more people does not solve the process
When release delays increase, organisations often respond by adding quality coordinators, expediters or administrative support.
More people may reduce the backlog temporarily. They do not remove the underlying handover.
If inspection results still need to be copied from one system to another, the process remains dependent on manual action.
If approvals still sit in email, the status remains difficult to track.
If quality, inventory and sales orders still use separate identifiers, employees must continue reconciling them.
The organisation becomes faster at managing the gap without closing it.
This is common in growing manufacturing businesses. A process that worked when the company released ten batches a week becomes unmanageable at fifty or one hundred batches.
The business adds people because the systems do not scale across functions.
The role of manufacturing execution
A manufacturing execution system should do more than record that production has finished.
It should connect production completion with the controls required before the output becomes usable.
Depending on the industry, this may include:
- Operation-level inspections
- In-process test results
- Material verification
- Batch record completion
- Serial or lot capture
- Deviation approval
- Final inspection
- Release workflow
The system should make the state of the product clear throughout the process.
Instead of a binary choice between open and complete, the business may need statuses such as:
- Produced
- Awaiting inspection
- Testing in progress
- Under review
- On quality hold
- Approved for rework
- Released
- Rejected
These states allow planning, warehouse and customer teams to understand what the completed output actually means.
This is the operational value of connecting production and quality through Salesforce MES.
The objective is not simply to collect more shop-floor data. It is to make production status meaningful to the rest of the business.
Measure the release cycle as a business KPI
Manufacturers should measure the time between physical completion and inventory release.
Useful measures include:
- Average time from production completion to sample collection
- Average laboratory turnaround time
- Average time from result availability to approval
- Average time from approval to stock-status update
- Percentage of batches released within target
- Value of finished goods awaiting release
- Customer orders delayed by release status
- Rework and rejection rates by product, line and supplier
- Ageing of quarantine inventory
These measures should be segmented.
A single average may hide serious differences between products, sites, laboratories, shifts or inspection types.
For example, routine products may release within hours while one product family regularly waits several days for documentation review.
Once the business sees the delay clearly, it can determine whether the constraint is testing capacity, approval workflow, data entry, process design or system integration.
Reduce the delay without weakening quality control
The goal is not to release stock faster by reducing inspection or approval requirements.
The goal is to remove non-value-adding delay around the required controls.
Several improvements can help.
Trigger inspections automatically
The system should create the required inspection or test when the relevant event occurs, such as:
- Purchase receipt
- Production operation completion
- Finished-goods declaration
- Customer return
- Supplier change
- Process deviation
This removes the delay between the operational event and the quality team becoming aware of the work.
Link results directly to the affected stock
Inspection and test results should be recorded against the exact batch, lot, serial number or production order.
This prevents ambiguity over which inventory the decision applies to.
Make release rules explicit
The system should define the conditions required for release.
These might include all required tests passing, documents being attached, deviations being resolved and approval being completed by an authorised role.
Clear rules reduce reliance on personal interpretation.
Update availability immediately
When the release decision is approved, the related inventory status should change without a second manual transaction.
Passed stock should become available according to the rules. Failed or held stock should remain blocked.
Give customer-facing teams appropriate visibility
Sales and service users do not need access to every quality record.
They do need enough information to understand whether an order is waiting for production, testing, review or release.
This supports accurate customer communication.
The quality-versus-speed misconception
Quality and speed are often presented as opposing objectives.
In reality, a well-controlled process can improve both.
A disconnected process is slow because it requires checking, communication and reconciliation. It may also be risky because people can act on outdated information.
A connected process enforces the control while removing the unnecessary handover.
Held stock remains blocked reliably.
Passed stock becomes available sooner.
The organisation does not need to choose between compliance and responsiveness. It needs systems that apply the quality decision directly to the operational record.
The questions manufacturers should ask
A practical review can begin with five questions.
How long does it take between completing a production order and making the output available to promise?
How much finished inventory is currently waiting for testing, approval or status updates?
Can warehouse users accidentally allocate or ship stock that quality has placed on hold?
Can sales see why a completed order is not yet shippable?
How much time do quality and operations teams spend reconciling records between systems?
The answers often reveal that release management is not a small quality workflow.
It is a central operational process affecting cash, capacity and customer delivery.
Made is not the same as ready
Manufacturers invest heavily in producing efficiently.
They improve machine utilisation, shorten setup time, reduce scrap and optimise schedules.
But the commercial value of those improvements is limited when finished goods spend days waiting between completion and release.
A product generates revenue only when it can be delivered to the customer.
The period between made and shippable should therefore be managed with the same discipline as production lead time.
That means measuring it, identifying its constraints and connecting quality decisions directly with manufacturing and inventory.
The companies that close this gap do not achieve it by bypassing quality.
They achieve it by making quality part of the operating process rather than a separate step that reports back after production has finished.
