9.3 Maintenance Planning Principles & Job Packages

Maintenance Planning Principles & Job Packages

Quick Answer: Planning prepares future work by defining scope, sequence, hazards, skills, labor, material, tools, information, and acceptance criteria. The readiness gate confirms that constraints are controlled according to the facility's rules before scheduling.

The Core Mission of Maintenance Planning (SMRP BoK 5.3)

In unassisted maintenance environments, a journey-level technician assigned a work order typically spends less than 35% of their shift performing actual physical maintenance on equipment. Extensive observational delay studies across heavy industry show where an unassisted technician's time is lost:

• 20% to 25% spent walking back and forth to the storeroom, waiting at parts counter windows, or searching shelves for parts.
• 10% to 15% spent locating specialized tools, rigging, ladders, or rental equipment.
• 10% to 15% spent tracking down operations personnel for equipment isolation, Lockout/Tagout (LOTO) clearances, or hot-work permits.
• 5% to 10% spent deciphering ambiguous work orders or finding equipment manuals.

This leaves a dismal 25% to 35% Wrench Time (hands-on-equipment tool time). When an organization introduces professional maintenance planning, the planner methodically eliminates these operational delays in advance. By identifying parts, tools, hazards, access, information, and acceptance criteria in advance, planning can reduce avoidable execution delay and improve safe, quality completion. The effect must be measured locally; no fixed direct-work percentage or productivity multiplier is guaranteed.

The Fundamental Division: Planning vs. Execution

A useful role distinction separates preparation of future work from control of current execution:

• Planning (The Planner): Focuses primarily on future work over the site’s planning horizon. The planner defines WHAT must be done, HOW it will be accomplished, WHAT materials and tools are required, and HOW LONG it should take (estimated craft-hours).
• Execution (The Supervisor & Craftsperson): Focuses exclusively on current work (today's shift and the next 24 hours). The supervisor determines WHO will do the work and manages WHEN it is executed on shift, ensuring safety and precision craftsmanship.

Doc Palmer's Six Principles of Maintenance Planning

Richard "Doc" Palmer’s Maintenance Planning and Scheduling Handbook presents six influential planning principles. They are taught here as one operating model, not as the text of the SMRP outline or a universal staffing requirement:

Principle 1: Separate Department

In this model, planners are organized so daily execution pressure does not routinely displace forward planning. Other structures can work if they protect capacity and decision rights. If a planner reports to a craft supervisor, the supervisor will inevitably divert the planner into parts expediting, tool delivery, or relief supervisory duties during daily breakdowns, completely collapsing advance job preparation.

Principle 2: Focus on Future Work

Planners must focus strictly on future work—work scheduled for next week, two weeks out, or during the next planned outage. Protect planner capacity for future work. Execution leadership normally handles today’s response and expediting, with deliberate coverage for exceptions rather than routinely diverting planners. If planners are pulled into today's firefighting, future work is dispatched unvetted, generating more breakdowns and trapping the plant in an endless reactive death spiral.

Principle 3: Component-Level Files

Planners must maintain equipment files at the specific component level (using unique asset tags), rather than broad unit or department levels. When planning a job on PUMP-101-A, the planner consults the historical component file to see past work orders, actual hours spent, vendor drawing numbers, bearing clearance records, and previous technician redlines. This institutional memory ensures that the organization learns from past repairs and never solves the same technical problem twice.

Principle 4: Estimates Based on Craft Skills

Labor estimates must be based on the capabilities of an average, fully qualified journey-level craftsperson. Planners estimate the required craft disciplines (e.g., two mechanical technicians for 4 hours, one electrician for 2 hours), not specific individuals. Schedulers then use these standardized labor estimates to match total backlog hours against the weekly craft labor capacity.

Principle 5: Recognize Craft Expertise

Planners must respect the expertise of journey-level technicians. Job plans must never be condescending manuals that explain basic trade skills (e.g., planners should not explain how to loosen a standard bolt or use a socket set). Instead, job plans must focus on what to do, the critical sequence of disassembly, known safety hazards, special rigging requirements, and non-negotiable engineering tolerances (e.g., torque specs, shaft alignment limits, runout tolerances).

Principle 6: Measure Performance with Wrench Time

The primary measure of planning effectiveness is workforce wrench time. A planner's success is not evaluated by how many binders of paper they produce, but by whether craft technicians can arrive at a job site with pre-staged parts, correct permits, and clear specifications, enabling them to work continuously without administrative delays.

Anatomy of a Complete Maintenance Job Package

A Maintenance Job Package (also called a Work Package or Planned Work Dossier) is the complete assembly of technical and safety documentation delivered to the craftsperson before execution. A job package can be assembled digitally in the CMMS or in a controlled physical folder. The following seven components are a practical checklist; apply only the detail needed for the job and risk:

┌────────────────────────────────────────────────────────┐
│         ANATOMY OF A COMPLETE JOB PACKAGE              │
│                                                        │
│  1. Header & Scoping Statement (Asset, FLOC, Scope)    │

│  6. Special Tools, Rigging & Calibration Equipment     │
│  7. Commissioning, Testing & QA Acceptance Criteria    │
└────────────────────────────────────────────────────────┘

1. Work Order Header & Scoping Statement

Clearly defines the physical boundary of the task: equipment tag number, functional location, charging account/cost center, defect symptoms, and an unambiguous scoping statement stating precisely what will be repaired and what is excluded from the scope.

2. Step-by-Step Task Sequence & Precision Tolerances

A structured, logical breakdown of the repair procedure. Crucially, this includes precision engineering specifications: bolt torque values (in ft-lbs or Nm), tightening sequences, dial indicator runout limits, laser alignment collinear tolerances (e.g., angularity $\le 0.05\text{ mils/inch}$, offset $\le 2.0\text{ mils}$), and bearing clearance limits. It also highlights mandatory quality "Hold Points" where a supervisor or inspector must verify alignment before casing closure.

3. Safety Precautions, JSA & Environmental Controls

Identifies all potential hazards associated with the task: energy isolation Lockout/Tagout (LOTO) points, stored kinetic or hydraulic energy release, chemical Personal Protective Equipment (PPE), Confined Space Entry permits, Hot Work permits, and environmental spill containment procedures.

4. Craft Disciplines & Labor Hour Estimates

Specifies the required craft specialties (e.g., Millwright, Pipefitter, High-Voltage Electrician, Instrument Specialist), the recommended crew size, and the estimated duration in hours (e.g., 2 Mechanics $\times$ 4 hours = 8 craft-hours).

5. Bill of Materials (BOM) & Parts Staging Verification

Lists all required MRO items: part numbers, descriptions, quantities, and storeroom bin locations. It includes gaskets, mechanical seals, bearings, fasteners, lubricants, and filter cartridges. Crucially, the package verifies availability and identifies the reservation, kitting, delivery, or staging method required by the local readiness gate.

6. Special Tools, Rigging & Mobile Equipment

Identifies any tool beyond the technician's standard personal toolbox: hydraulic flange spreaders, 1-inch drive pneumatic torque multipliers, laser alignment kits, bearing induction heaters, scaffolding requirements, mobile crane rigging, or boom lifts.

7. Commissioning, Testing & Quality Acceptance Criteria

Specifies the mandatory post-maintenance operational checks required before returning the asset to Operations: motor bump-test for correct rotational direction, dynamic vibration baseline measurement, thermal baseline scan of electrical lugs, dynamic seal leakage check, and dual operational sign-off.

Parts Kitting, Staging & Storeroom Integration

No planned job should ever be scheduled until its required materials are physically in the plant. The bridge between maintenance planning and execution is the Storeroom Kitting & Staging Process:

Rules of Staging

1. Do not ignore a material constraint: The readiness decision must confirm that required material will be available under the facility's execution plan. Critical or unusual parts may need physical verification and staging; common consumables may be controlled through a different approved method.
2. Secure Kitting Areas: Kitted bins must be stored in access-controlled staging cages within the storeroom. Staged kits should be secured and inventory-controlled. If an urgent job requires a staged part, authorize and record the transfer, then restore the affected kit and reassess its readiness. If emergency parts are needed, storeroom inventory protocols must record the transfer immediately.

Standard Job Plans & The Continuous Improvement Feedback Loop

In industrial facilities, up to 80% of maintenance tasks are repetitive over a multi-year cycle (e.g., pump overhauls, motor replacements, conveyor belt splices, control valve calibrations). Planners should not reinvent the wheel for every work order. Instead, they build a centralized library of Standard Job Plans (SJPs) in the CMMS.

The Technician Feedback Loop

A standard job plan is never static; it is a living document refined through the Planner Feedback Loop. When a craftsperson completes a job, they are required to provide constructive technical feedback on the closed work order:

• Did the job take more or fewer hours than estimated? Why?
• Were any parts missing, incorrect, or obsolete?
• Were special tools needed that were not listed in the package?
• Were procedural steps out of sequence or missing critical torque values?

The maintenance planner reviews closed work orders weekly, extracts technician redlines, and updates the master Standard Job Plan in the CMMS. This closed-loop process validates craft expertise, builds technician pride in organizational systems, and ensures that every job plan becomes progressively safer, faster, and more accurate over time.
