Maintain equipment and manage maintenance

An alarm, delayed repair or fleet result can lead to different questions. Open the Method for the result you need now, using evidence that is already adequate for it. The six ordinary maintenance entries offer direct starts; the full pattern index remains available when none fits.

Your question	Open	What you can obtain
Which equipment, actual configuration and required use does the maintenance question concern?	MNT.1 - Identify the Maintained System, Use, and Permission Boundary	A bounded maintained System and use, with the operating and permission conditions that change the answer.
Should we keep the current maintenance policy or choose another task?	MNT.2 - Select and Reopen the Maintenance Policy	An applicable retain or change decision for the failure and use. Keeping a policy requires an adequate basis, not merely an unproved alternative.
What can this failure history tell us?	MNT.3 - Establish Degradation and Failure Evidence for Maintenance	A qualified failure account that distinguishes events, exposure, mechanism and cause without claiming more than the evidence supports.
Does this alarm or trend show a changed condition under the actual load and speed?	MNT.4 - Monitor and Interpret System Condition for Maintenance	A condition interpretation with its measurement and comparison limits. It need not predict remaining life or select a repair.
Are the spare, tools, competence and support suitable and available for the selected task?	MNT.5 - Prepare Maintenance Service Capability, Spares, Tools, and Authority	Task-specific readiness or the exact missing contribution. Missing spare applicability can prevent replacement without defeating a sufficient recommendation.
What maintenance response can we recommend now?	MNT.6 - Diagnose Condition and Choose a Maintenance Response	A supported recommendation or selected intervention from the plausible responses. Finish sufficient advice; investigate or perform physical work only when that further result is needed.
Will the whole intervention fit the operating commitment?	MNT.7 - Coordinate Maintenance Intervention and Continuing Operation	A qualified comparison of the complete outage with the supplied capacity and service conditions, including testing, restoration, hand-back and contingency.
What makes it possible to begin this protected intervention?	MNT.8 - Isolate, Make Safe, and Authorize the Maintenance Intervention	The actual isolation, protection and bounded permission for the selected act, or its unmet condition. A work order alone establishes none of them.
What intervention actually took place, and what state did it leave?	MNT.9 - Perform and Record the Maintenance Intervention	Performed-work and actual-configuration evidence, including consequential deviations and interruptions; a plan is not that evidence.
Has the required functioning been restored?	MNT.10 - Verify Restored Functioning after Maintenance	A functioning result for the actual configuration, representative use and qualified acceptance basis; broader duty and resumed-use permission remain separate.
Who can resume which use of the returned equipment?	MNT.11 - Hand Back and Authorize Resumed Use after Maintenance, with Certification Where Required	A reconciled returned state, control transfer and applicable resumed-use decision. A successful test does not automatically supply the authority.
Which history applies to this installed component and configuration?	MNT.12 - Maintain Maintenance Information and Configuration Continuity	Maintenance-event and configuration continuity for the receiving question, including contradictions that change what can be inferred.
Do fleet results justify changing or retaining the programme?	MNT.13 - Coordinate the Maintenance Programme and Fleet Learning	An exposure- and event-qualified comparison and supported programme decision. Raw counts alone establish neither a fair rate comparison nor a causal policy advantage.
Should we retain, revise or replace this maintenance Method or tool?	MNT.14 - Compare Maintenance Methods for Retention or Change	A same-result comparison and supported retain, revise, replace, branch or stop decision. A new trial is conditional on an attainable, decision-changing answer worth its whole burden.
Why can two individually feasible jobs not be carried out together?	MNT.15 - Reconcile Simultaneous Maintenance, Operation, and Support Work	A whole-combination account of shared specialists, capacity, fallback and protection, with a feasible allocation or timing change, or the exact unmet commitment.
Is the revised maintenance practice actually being continued or changed?	MNT.16 - Deliberately Continue and Change Maintenance Culture	An account distinguishing access, transmission, actual enactment and effects, with a supported continuation or change decision; a new manual is not proof of changed practice.

A maintenance question can concern one pump or a fleet: it seeks a maintenance policy, intervention or programme result that preserves or restores required functioning. Choosing continued use, renewal, replacement, repurposing or withdrawal by value, costs, risks and service effects is a distinct asset-management question even for one pump. For that comparison, open Engineering Asset Management, starting with EAM.8 and the applicable asset and service basis. A verb such as “replace”, a long horizon or a large asset count does not settle which result is needed.

Stop when the requested result is adequate. Selected equipment work still needs its applicable procedures, competent means, protection and authority. The MNT cases are constructed teaching examples, not field validation, equipment instructions or permission.
