What is Operational Readiness? A Guide for Mining and Heavy Industry

Operational Readiness Defined

Operational readiness (OR) is the state where an asset, facility, or plant has the people, processes, systems, and strategies in place to operate at design intent from handover. It covers maintenance strategy, spare parts, training, CMMS configuration, and documentation, each validated through a structured gate review before the asset goes live.

Under ISO 55001:2024, the current edition of the asset management standard, an organisation is expected to plan for the whole asset lifecycle from the point of acquisition or construction, not once the asset is already running. An operational readiness study is how that obligation gets met in practice, and it is the core of the operational readiness service we deliver on capital projects.

For how OR sits within broader asset management planning, see our guide to operational readiness for mining assets.

Why Operational Readiness Matters

When operational readiness is missing, the cost does not arrive as a line item. It arrives as reactive maintenance through the first year, emergency spares bought at a premium, and unplanned downtime during ramp-up, the phase where every lost tonne is hardest to win back.

The pattern is consistent. The asset enters service before the maintenance strategy, the spare parts holdings, and the team’s capability are ready to support it. So the operators learn the equipment by breaking it, the planners build the strategy while firefighting, and the stores hold the wrong spares until failures teach them otherwise. The most expensive phase of an asset’s life becomes the one you planned for least.

On a new iron-ore plant, HolisticAM built 353 planned routine tasks across 23 asset lines as 9 SAP-ready deliverable types, in a 12-week pre-commissioning programme before first ore. That is the difference a structured OR program makes. Gaps close before first production, not after the first breakdown. The maintenance strategy is written against the real failure modes, the spares are stocked to criticality and lead time, and the CMMS holds working plans the day the asset starts. You can see the full engagement in our operational readiness case study for a new iron-ore plant.

When is Operational Readiness Required?

Operational readiness applies across a range of capital project scenarios:

• New mine development. Greenfield sites need a full OR program spanning every asset class, from the processing plant to the mobile fleet.
• Plant expansion. Adding capacity to a running site brings in new equipment that existing maintenance strategies and CMMS data do not yet cover.
• Asset recommissioning. Assets returning from care and maintenance need updated strategies, a spare parts review, and a condition assessment before they run again.
• Major capital projects. Any project above a defined capital threshold should carry an OR program as a project deliverable, not an afterthought.
• Fleet replacements. A new equipment model or a new OEM means updated maintenance strategies, BOMs, and training for the maintenance team.

The emphasis shifts with the project type. A greenfield build, a brownfield expansion, and the restart of an idled plant each load the readiness effort differently, as set out in greenfield vs brownfield vs restart.

The call to start OR belongs at project sanction, not during construction or commissioning.

Key Elements of an Operational Readiness Study

A structured OR study delivers the following:

• Asset criticality assessment. Ranks assets by consequence of failure so OR effort lands where it matters. See our reliability engineering services for the criticality methodology.
• FMECA and maintenance strategy. Identifies failure modes and builds the maintenance tasks that address them, asset by asset. On the most critical systems this is carried through as RCM studies at the design stage, before the equipment arrives. See our FMEA and FMECA services.
• Spare parts strategy. Sets initial holdings against criticality, lead time, and failure rate, so you avoid both stock-outs and dead stock at commissioning.
• CMMS configuration. Turns the maintenance strategy into working orders, task lists, and maintenance plans inside your CMMS, built on sound master data. See our master data management services.
• Training plans. Maps the skills operations and maintenance teams need, then schedules the training to close the gap before handover.
• Readiness checklists and gate reviews. Verify OR deliverables at each project phase, so gaps are found and closed before the next phase proceeds. Our operational readiness checklist sets out 27 checkpoints and the date each must be complete by.

The Operational Readiness Process

An OR program runs in phases alongside the capital project schedule. The work inside those phases is organised into nine streams, explained in the operational readiness framework:

1. Scoping. Define the OR scope, asset register, project interfaces, and deliverables. Agree the gate review schedule with the project team.
2. Analysis. Run the asset criticality assessment and FMECA on priority assets. Identify failure modes, consequences, and the maintenance tasks they call for.
3. Strategy development. Build the maintenance strategy, spare parts strategy, and inspection plans. Align them with OEM recommendations and the operational context.
4. CMMS setup. Build the asset hierarchy, master data, work orders, and maintenance plans in the CMMS. Validate the data before go-live.
5. Training. Deliver training for operations and maintenance teams, covering both the equipment and the strategy behind it.
6. Gate review. Verify against the readiness criteria. Find and close gaps before commissioning begins.
7. Handover. Transfer every OR deliverable to the operations team with documented handover records, and confirm ongoing support.

Operational Readiness vs Commissioning

The two get confused often, yet they answer different questions and are run separately.

Commissioning proves that equipment is mechanically complete, electrically connected, and works to design specification. It is an engineering and construction activity.

Operational readiness proves that the maintenance and reliability program is in place, so the operations team can sustain that equipment from day one. It is an asset management activity.

Both run in parallel through construction and pre-commissioning. Commissioning cannot stand in for OR. Finish commissioning without a matching OR program and you get the cost and delay outlined above. An asset can be mechanically complete and still be operationally unready.

Maintenance readiness is a related term often used as though it means the same thing. It does not. Maintenance readiness is one stream of the nine, covering the maintenance strategy, spares, and CMMS build. The distinction is set out in maintenance readiness vs operational readiness.

Operational Readiness in Mining

Mining brings OR challenges that other sectors do not:

• New processing plants. High-criticality assets such as SAG mills, ball mills, flotation circuits, and thickeners need detailed FMECA and a fully configured CMMS before handover. Spare parts calls made at commissioning carry long lead-time consequences that run for years.
• Fleet introductions. A new truck or excavator model means updated maintenance strategies, training, and spare parts BOMs. Expanding an existing model is lower risk, but still needs CMMS updates and stores alignment.
• Recommissioned concentrators. Assets returning from care and maintenance carry elevated risk from degradation during layup, outdated documentation, and workforce turnover. A recommissioning OR study should pair a physical condition assessment with the strategy and systems work.

HolisticAM has delivered OR programs across greenfield and brownfield mining projects in Queensland, Western Australia, and internationally, and supports gold and mineral processing plant builds in West Africa. Our reliability engineers have held site roles in maintenance and reliability management, and bring that experience to each engagement.

Operational Readiness Consulting in Australia and West Africa

HolisticAM provides operational readiness consulting to mining and heavy industry across Australia, and to gold and mineral processing plant builds in West Africa. Our OR programs run alongside your capital project schedule, delivered by reliability engineers who have held site roles in maintenance and reliability management.

The approach covers the full OR scope: criticality assessment, FMECA, maintenance strategy, spare parts, CMMS configuration, training, and gate reviews. The deliverables are practical, transferable, and owned by your team at handover. Our operational readiness service page shows how the full engagement is structured.

Sites often ask whether that reliability capability is better built in-house, bought as a defined campaign, or contracted as an ongoing service. We compare the three in in-house reliability engineer vs consultant vs managed service, and set out the role itself in what a reliability engineer does.

If you are planning a capital project, plant expansion, or recommissioning, the time to start operational readiness is now, not at mechanical completion. Leave it until the asset is built and you are already paying for the gap.
