The floor walk¶
ISO 22301, Clauses 4, 5 and 8.1: context, leadership, and operational planning.
Every continuity plan rests on knowing what the factory is. Before charting storms or building emergency systems, walk the floor: establish what the business continuity management system covers, who answers for it, and what is actually running out there. A plan scoped around an out-of-date picture of the factory protects the factory that used to exist.
Scope and leadership first¶
Clause 4 asks for context: which products, services, and sites the continuity system covers, which interested parties depend on them, and what the organisation has decided is in and out of scope. A scope statement that can be read aloud in one paragraph, without anyone in the room frowning, is a reasonable test.
Clause 5 places responsibility with top management: an approved continuity policy, roles and responsibilities assigned, and resources committed. Continuity that lives entirely inside the operations team, without board-level ownership, is a gap auditors notice early, and disruptions notice earlier.
The factory’s heartbeat¶
Assets are the essential cogs that make production run. From controllers to networks to supporting IT, each element has a direct impact on uptime, safety, and operational resilience. Any undocumented, mismanaged, or unsupported asset is a potential point of failure, slowing recovery and increasing risk during a disruption.
Industrial controllers and PLCs
These devices orchestrate production processes. Failure or misconfiguration can halt operations instantly.
Checks: Redundancy in place? Lifecycle documentation complete? Replacement procedures defined? Maintenance schedules adhered to?
Typical gaps: Missing spare units, unclear ownership, incomplete update or patch records.
SCADA servers and HMIs
Central monitoring and control; a single point of visibility for operators.
Checks: Backup routines tested? Failover procedures validated? Access controls documented?
Typical gaps: Outdated backup logs, undocumented failover steps, misaligned operator permissions.
Networks and communications
Segmented and monitored networks prevent a single failure from cascading across production.
Checks: Network diagrams current? Redundant paths verified? Monitoring and alerting in place?
Typical gaps: Zones not clearly defined, undocumented network changes, monitoring gaps in critical paths.
Field devices and sensors
They collect process data and trigger safety or automation functions. Faulty sensors or missing calibration can disrupt production or safety.
Checks: Spares available? Calibration documented and current? Monitoring of device health in place?
Typical gaps: Sensors missing in documentation, overdue calibration, unmonitored devices.
Physical infrastructure
Power supplies, enclosures, and environmental controls support everything else. A failure here stops the factory even if devices are functional.
Checks: UPS and generators tested? Cooling and environmental controls operational? Access controlled?
Typical gaps: Outdated maintenance logs, untested backup power, unclear responsibility for environmental systems.
Supporting IT systems
ERP, reporting, and logging systems tie OT processes into organisational operations. Their failure can prevent informed decision-making during incidents.
Checks: Backups tested? System dependencies documented? Logging and alerting operational?
Typical gaps: Disconnected IT-OT systems, incomplete logs, undocumented recovery steps.
Executive gap-spotting¶
Comprehensive documentation: Are all critical assets recorded and mapped to continuity priorities? Missing items are blind spots.
Ownership clarity: Does each asset have a responsible owner or custodian? Ambiguity means delayed response in disruption.
Lifecycle completeness: Are installation, maintenance, updates, and decommissioning steps fully documented and current?
Criticality ratings: Are assets rated by operational impact to prioritise recovery efforts? Without prioritisation, recovery wastes time and resources.
Redundancy and readiness: Are backups, spares, and failover mechanisms in place and tested?
Walk through the factory mentally: each asset wants to be visible, documented, and accounted for. Anything you cannot immediately point to or explain is a gap waiting to disrupt operations.
Asset documentation is a model of the factory’s operational state at a point in time. The model ages: assets are upgraded, replaced, moved, or taken offline without the documentation following. When the documented state and the actual state diverge, the gap is not primarily a record-keeping failure: it is evidence that the process maintaining alignment between documentation and reality has a mismatch. Recovery procedures that depend on stale asset documentation will fail at the moment they are most needed.
Output¶
By the end of this stage, the organisation has a scope statement for the continuity system, an approved policy with named roles and board-level ownership, and an asset register mapped to continuity priorities with owners, criticality ratings, and current lifecycle records. This is the map the storm charts are drawn on.
