The chain
The records
Asset
Asset
A physical thing you maintain — a pump, a compressor, a generator. Assets form a hierarchy:
a bearing belongs to a pump, which sits on a production line, in a building, at a site. Work,
cost, downtime and failures all roll up that tree.An asset carries meters, cover, a criticality, a health score and a full history.
See the asset register.
Work request
Work request
Somebody reporting that something needs attention. A request is not a job — it is a claim
that there might be one. Triage decides: convert it to a work order, or reject it.Requests keep the reporter’s own words, which is why they exist as a separate record rather than
as a draft job. See work requests.
Work order
Work order
The job itself, and the most important record in the product. It carries the asset, the type
(preventive, corrective, breakdown, inspection), the priority and its service level, who it is
assigned to, what it needs, what it cost, and every state change it has been through.See inside a work order.
Maintenance plan
Maintenance plan
A rule that raises work orders on its own. A plan names the assets it covers and one or more
triggers — a calendar interval, a meter threshold, an event, or a measured condition —
combined with ANY or ALL.A plan can also raise an inspection round alongside the work order.
See the plan builder.
Requirement
Requirement
What a job needs before it can be done: a part, a tool, a skill, or a vendor.
Requirements come from the maintenance plan, or are added to the job directly.All four are one thing to the system, which is why the readiness check can answer “can this be
done” in a single question rather than four.
Readiness
Readiness
Whether a job can actually be executed right now. Readiness reads the requirements and reports
what is missing — a part not in stock, a tool out on another job or overdue for calibration, a
skill or certification nobody available holds.Readiness is a fact about the job, not a status. A job can be Assigned and not ready.
Entitlement
Entitlement
Who pays. When work is raised against an asset, the system evaluates the contracts and
warranties covering it and records the decision — covered or not, by which agreement, with the
evidence it used.The decision is recorded rather than recomputed, so a repair billed internally on a machine the
manufacturer would have covered is visible instead of silent.
See entitlements and claims.
Failure
Failure
What actually broke, recorded against the asset. Failures drive downtime, MTBF and the bad-actor
ranking on Reliability. A failure is raised from the job that fixed it, or
from a failed inspection check.Classifying one means saying what kind of failure it was, what caused it, and by what mechanism
— three separate lists, because collapsing them tells you nothing about what to change.
Investigation
Investigation
Why the same thing keeps happening. An investigation is opened against an asset, works down to
findings you can evidence, and concludes on a root cause — which it will not do until one is
marked.What comes out of it is actions, corrective or preventive, each followed until somebody has
confirmed it was done and then reviewed whether the problem actually stopped.
See root cause.
Sites and scope
An organisation has sites — plants, depots, buildings. Inside a site is a location tree: building, floor, line, room. Assets live at locations. Two separate things control what you can see:Statuses are yours, not ours
Every lifecycle in the product — work orders, requests, assets, vendors — is a state model your organisation owns. You can rename states, add them, and change which moves are allowed. What a status means is carried by flags rather than by its name: whether it counts as open, whether it stops the service-level clock, whether parts may be consumed against it, whether a technician may still edit the job. That is why renamingWAITING_PARTS to “Awaiting spares”
changes the label everywhere and breaks nothing.
