Operational risk

Operational risk commonly refers to the risk of loss, disruption, or performance degradation resulting from inadequate or failed processes, people, systems, or external events in an organization’s day-to-day operations. In industrial and manufacturing environments, this focuses on how production, maintenance, quality, IT/OT systems, and supply chain activities can fail or behave unexpectedly.

Key characteristics in manufacturing and industrial operations

In a plant or regulated manufacturing setting, operational risk typically includes the potential for:

• Process failures such as unstable production processes, incorrect setups, missed inspection steps, or inadequate work instructions that can lead to scrap, rework, or unsafe product.
• People-related issues including skill gaps, insufficient training, fatigue, human error on the shop floor, or non-adherence to standard work.
• System and technology failures such as MES, ERP, QMS, OT/PLC, or network outages; incorrect system configuration; data integrity issues; or loss of traceability and genealogy.
• External events affecting operations including supplier failures, material shortages, utilities interruptions, cyber incidents impacting OT systems, or natural events that disrupt production.
• Compliance and quality execution breakdowns such as missing records, incomplete device history records (DHR), unrecorded deviations, or failure to follow regulated procedures.

Operational risk is usually considered separately from purely financial, strategic, or market risks, even though it can create financial impact through downtime, cost of poor quality, delays, or regulatory findings.

How operational risk shows up in workflows and systems

In practice, operational risk is managed by identifying how routine activities could fail and what controls exist in the systems and workflows. Examples include:

• Standardized procedures and digital work instructions to reduce variation in how tasks are performed and make training and audits more consistent.
• Checks, approvals, and interlocks in MES/ERP/QMS such as enforced routing steps, electronic signoffs, version-controlled instructions, and automated data capture.
• Monitoring and visibility through OEE, NPT tracking, alarms, and dashboards that highlight process instability, recurring downtime causes, or yield drops.
• Nonconformance and CAPA workflows to capture failures, investigate root causes, and implement corrective and preventive actions that reduce future operational risk.
• OT and cybersecurity controls to reduce the risk of system unavailability or data integrity issues due to cyber incidents in industrial networks.

In regulated industries, operational risk is often tied to documentation and evidence: how easily an organization can demonstrate that operations were executed as specified, with appropriate controls and records in place.

Common confusion

• Operational risk vs. safety risk: Safety risk focuses on potential harm to people or environment. Operational risk is broader and includes production, quality, system, and compliance disruptions, although safety incidents are often one category of operational risk.
• Operational risk vs. strategic or financial risk: Strategic risk relates to long-term business decisions and market positioning; financial risk relates to factors like currency, credit, or liquidity. Operational risk centers on how daily operations and supporting systems can fail, even if the impact ultimately appears as financial loss.
• Operational risk vs. project risk: Project risk is tied to one-time initiatives (such as a new MES rollout). Operational risk focuses on ongoing, repeatable activities in production and service delivery.

Relation to manufacturing standards and practices

Many industrial and quality frameworks treat operational risk as a core element of managing a plant or value stream. Typical practices include risk-based thinking in quality management systems, process validation, change control, and layered process audits, all of which aim to identify, evaluate, and reduce sources of operational risk in everyday manufacturing activities.
