There is a point at which process discipline stops improving control and starts obscuring operational reality.
Most organisations do not recognise when they cross that boundary.
A workflow may contain defined activities, approvals, statuses, responsibilities, and escalation paths. On paper, the process appears controlled. Execution can be measured, compliance can be reported, and every activity has an assigned owner.
Then the process encounters the shopfloor.
A recurring quality defect emerges during a critical production run. The equipment has shown intermittent instability, but no definitive failure. Maintenance has an intervention planned, although production cannot easily release the asset. A supplier batch is under suspicion. Engineering wants additional evidence before changing process parameters. Quality cannot accept the risk of another escape.
The workflow may specify what should happen next.
The operational reality is that several things may need to happen simultaneously, and the appropriate response may change as new evidence appears.
That distinction is fundamental.
Workflow is highly effective when the work is sufficiently predictable. It becomes counterproductive when predetermined sequencing is used as a substitute for governing uncertainty.
The problem is not standardisation
Industrial organisations need standards.
Without them, every abnormal condition risks becoming an exercise in improvisation. Decisions become dependent on individual experience and memory. Lessons are difficult to retain. Accountability becomes ambiguous. Continuous improvement becomes difficult because there is no stable baseline against which actual behaviour can be evaluated.
But standardisation and rigid workflow design are not the same thing.
A standard can define expected operating conditions, mandatory controls, evidence requirements, decision rights, escalation thresholds, and closure criteria without assuming that every operational situation will follow the same predetermined sequence.
This distinction is particularly important in maintenance, quality management, production recovery, supplier incidents, engineering changes, and complex troubleshooting.
These environments contain repeatable activities, but the sequence of work often depends on what is discovered during execution.
Attempting to eliminate uncertainty from the process model does not eliminate uncertainty from operations.
It merely relocates it.
When the formal process and the real process diverge
When a workflow cannot represent operational reality, people adapt.
Maintenance is contacted directly. An Excel file appears. A Teams conversation becomes the real coordination mechanism. A quality engineer receives photographs outside the formal system. A transaction remains artificially open because the investigation is still evolving. The closest available reason code is selected even though it does not accurately describe the event. A status is advanced because leaving it unchanged would negatively affect a KPI.
From the system perspective, the workflow continues to progress.
From the operational perspective, the real process has moved elsewhere.
This is one of the least visible consequences of excessive workflow rigidity: the formal process becomes cleaner while the operational process becomes less observable.
More digital transactions therefore do not necessarily mean more operational control. Critical decisions may simply have migrated outside the governed system.
False process visibility
Process data creates value only when it represents meaningful operational behaviour.
If people must distort reality to satisfy the workflow, the resulting data becomes structurally misleading.
A maintenance technician may close one work order and create another because the system cannot represent an evolving diagnosis. A quality team may use an artificial status because containment, investigation, and production recovery are progressing at different speeds. A supervisor may bypass a prescribed approval because waiting would stop production and document the decision retrospectively.
Such behaviour may represent non-compliance.
But not always.
Sometimes it is evidence that the process model is less capable than the operational problem it is intended to govern.
This matters directly for Process Mining. Event data may reveal loops, rework, deviations, repeated transitions, and unexpected paths. Those patterns are valuable, but deviation should not automatically be interpreted as waste or lack of discipline.
Some deviations expose weak execution.
Others expose weak process design.
The deviation is evidence. Its interpretation requires operational context.
Decision latency disguised as control
Rigid workflows also tend to equate control with sequential approval.
In high-pressure industrial environments, that assumption can generate a paradox: the organisation gains more formal control while becoming slower at responding to the actual operational risk.
Consider an intermittent equipment-related quality defect.
Production may want to continue under controlled conditions. Quality may require immediate containment. Maintenance may need diagnostic access. Engineering may require additional measurements to distinguish equipment degradation from process drift.
A simple workflow might impose a sequence:
identify the problem, assign responsibility, investigate, approve the action, execute the action, verify the result, and close the case.
Real operations may require parallel diagnosis, temporary containment, conditional production, repeated inspection, additional measurements, and reassessment as evidence changes.
The management challenge is therefore not to force every activity into a predefined sequence.
It is to ensure that the right decisions are made by the right people, using sufficient evidence, within explicit operational boundaries.
When workflow sequencing delays that coordination, the workflow itself has become an operational constraint.
Task ownership is not case accountability
Traditional workflows usually assign responsibility activity by activity.
That model works well for transactional processes.
It is less effective when the operational condition crosses production, quality, maintenance, engineering, logistics, and planning.
Each function may perform its assigned activity correctly while nobody remains accountable for the overall outcome.
Maintenance repairs the equipment.
Quality releases the product.
Production restores the schedule.
Engineering changes a parameter.
Planning reschedules the orders.
Every function closes its task.
Three weeks later, the same condition returns because no one remained accountable for understanding and resolving the incident as a single evolving operational case.
Task ownership is not the same as case accountability.
Complex operational work requires both. Specialist teams need clear responsibility for individual actions, but somebody must also remain accountable for the condition across functional boundaries until the evidence supports recovery and closure.
That is not merely an organisational distinction. It is a BPM design principle.
Workflow debt
Organisations frequently discuss technical debt.
They should also recognise workflow debt.
When every exception is translated into another workflow branch, the process model gradually accumulates complexity.
Another routing condition is added.
Another approval appears.
Another status is created.
Another exception path is configured.
The result is an increasingly large decision tree intended to anticipate operational reality in advance.
But complex industrial environments continuously generate combinations that designers did not foresee. Over time, the workflow becomes difficult to understand, expensive to maintain, and fragile when processes, organisations, equipment, or systems change.
Automation can intensify the problem.
A weak manual workflow creates local inconvenience.
A weak automated workflow can reproduce the same design assumption consistently across an entire operation or network.
Automation does not correct poor process assumptions. It institutionalises them.
Stable core, adaptive edge
The alternative is not to abandon workflow management.
It is to become more precise about where prescriptive workflow belongs.
Many industrial processes contain a stable core that should be standardised rigorously.
Safety checks should not become optional because the incident is complex. Mandatory quality evidence must remain mandatory. Regulatory approvals require control. Equipment isolation procedures require discipline. Traceability requirements need structure. Master data requires governance.
These are areas where flexibility can create unacceptable risk.
Around that stable core, however, some operational work requires an adaptive edge.
Here, the system should govern the case without attempting to prescribe every possible sequence in advance.
The governance model should make explicit:
- the operational objective and current risk;
- the accountable case owner;
- mandatory evidence and non-negotiable controls;
- authorised decision rights;
- escalation thresholds;
- relevant production, quality, maintenance, and engineering context;
- actions already attempted and their outcomes;
- functional dependencies;
- criteria for containment, recovery, and closure.
This is not uncontrolled flexibility.
It is bounded flexibility.
The organisation remains rigorous about what must be controlled while recognising that the exact sequence of work may legitimately evolve as evidence develops.
Industrial systems must support the decision process, not only the transaction flow
This distinction becomes increasingly important as BPM interacts with MES/MOM, CMMS/EAM, QMS, ERP, historians, and operational analytics.
Consider an equipment-related quality incident.
MES may provide the production order, material genealogy, machine state, and affected units. CMMS may contain maintenance history and open work orders. QMS may govern non-conformance and containment. ERP may contain order priorities and material availability. The historian may contain the process signals required for diagnosis.
All of these systems can be technically integrated while the operational decision process remains fragmented.
Connectivity alone does not create operational understanding.
The process layer must help the organisation assemble context, preserve evidence, coordinate responsibilities, manage escalation, and maintain accountability as the situation evolves.
At that point, BPM is no longer simply a mechanism for routing tasks.
It becomes a governance layer for operational decision-making.
Its purpose is not merely to determine the next activity. It is to establish how work can progress responsibly when the next appropriate action depends on risk, evidence, specialist judgement, and changing circumstances.
AI increases the need for governance
Industrial AI makes this distinction even more important.
Generative AI and operational agents can increasingly assist with summarising evidence, retrieving historical cases, detecting patterns, and recommending possible actions.
Those capabilities can improve decision support.
They do not remove uncertainty.
An AI system may suggest that a recurring defect resembles a previous equipment-alignment problem. That information may be useful, but the decision to stop production may still depend on customer exposure, containment effectiveness, asset criticality, maintenance resources, available inventory, and the current production plan.
The recommendation is only one element of the operational context.
AI can support reasoning. It should not convert incomplete evidence into apparent certainty.
As operational systems become more adaptive, governance must therefore become more explicit rather than less so. Organisations will need clear decision rights, evidence requirements, accountability, and escalation rules governing collaboration between people, process logic, operational systems, and AI.
The architecture may become more flexible.
Accountability cannot become more ambiguous.
BPM should govern reality, not defend the diagram
There is an understandable desire to simplify processes.
Simplicity improves training, automation, scalability, and control.
But operational complexity does not disappear because the process model is linear.
The more useful objective is to determine what genuinely deserves strict standardisation, what requires professional judgement, and how both can coexist under disciplined governance.
A mature BPM capability does not require people to force operational reality through a predefined diagram.
It uses process models to establish standards, systems to preserve context, data to expose actual behaviour, and governance to make exceptions visible and manageable.
The practical test is therefore not whether the organisation can demonstrate that every activity followed the prescribed sequence.
The more important questions are whether safety, quality, delivery, traceability, asset reliability, and accountability remained protected—and whether the organisation retained enough visibility to understand why the real process behaved as it did.
That is a substantially more demanding ambition than workflow automation.
It is also much closer to what operational control actually means in an industrial environment.
Before adding another workflow branch, approval, or status, three questions are worth asking:
Where are people formally following the workflow while moving the real decisions outside the system?
Which exceptions are sufficiently repeatable to justify a predefined path, and which should instead be managed as governed operational cases?
Are the controls protecting the operational outcome—or merely protecting the process diagram?
