How the whole system fits

Maintenance planning and scheduling: the five-stage weekly system

How maintenance planning and scheduling work together: the five stages from request to close-out, who owns each, the numbers to track and where to start.

Plant Floor · Practical maintenance management

Maintenance planning and scheduling is the weekly system that turns a request into finished work. Planning decides how a job will be done and what it needs. Scheduling decides when it will be done, by whom, and holds that commitment with production. Neither works alone. Planned jobs with no protected schedule get raided. A schedule full of unplanned jobs dies by Tuesday.

In Fix the System, planning and scheduling sit inside a cycle of five stages: identify, plan, schedule, execute and close out. Each stage hands its output to the next. This page maps the whole cycle and links the tool or template for each stage.

The five stages of maintenance planning and scheduling

Stage	What it produces	Owner	Numbers to track	Start with
1. Identify	A written notification, triaged within a day	Operators write it; a triager routes it	2 to 6 notifications per operator a month. First triage under 24 hours	Notification template
2. Plan	A ready-to-execute job: parts, procedure, hours, safety, drawings. Kit staged 48 hours ahead	Maintenance planner	Over 75% of work with a written job plan. 60% or more of planner hours spent planning	What a maintenance planner does
3. Schedule	A committed weekly schedule with operations, plus a 15% to 20% break-in reserve	Scheduler or supervisor, with operations	Schedule compliance over 85%. Break-in work under 15%	Maintenance scheduling tool
4. Execute	The job done to plan, safely, with data captured at the asset	Crew lead and technicians	Wrench time 55% to 65% at Tier 3. Pre-job briefings and lockout verification 100%	Wrench time
5. Close out	A record the next planner can use: parts, failure code, readings, deviations, notes for next time	Technician, audited by the supervisor	Close-out quality over 70% within 90 days, over 85% within 180. More than 5 loop actions a quarter	Close-out notes guide

The targets are the book's working targets, one chapter per stage. Each stage has its own 90-day installation in the book.

Maintenance planning vs maintenance scheduling

Planning works on future weeks. The planner scopes the job, writes the parts list, procedure, hours estimate and safety requirements, and stages the kit. Its output is a job a technician can start without a scavenger hunt. Template: the maintenance job plan template.

Scheduling works on next week. The scheduler counts real crew hours, holds a reserve for break-ins, loads ready jobs by priority, agrees production windows in a 30-minute meeting and freezes each job 48 hours before it starts. Its output is a schedule operations can plan production around.

In a small plant one person often does both jobs. That works as long as planning time stays protected. The planner standard work week shows how by plant size.

The four-week rhythm

A schedule is only as good as the work that reaches it ready. The scheduling tool uses a rolling four-week look-ahead:

4 weeks out: make the future visible. Needs: known campaigns, critical PMs, shutdown windows, and high-risk corrective work. If skipped: the schedule week arrives with surprise work and no prepared options.
3 weeks out: shape the work. Needs: parts blockers, access needs, job estimates, and operations conflicts. If skipped: the meeting becomes a backlog debate because work readiness is unknown.
2 weeks out: draft the week. Needs: draft schedule, realistic labor hours, staged materials, and release windows. If skipped: the weekly baseline gets loaded with hope instead of executable work.
Next week: publish the weekly baseline. Needs: named reserve, confirmed windows and the original job baseline. If skipped: the week starts as a suggestion, then every urgent request rewrites it.

The weekly meeting itself has a fixed agenda: the weekly scheduling meeting agenda. The rule that protects the result is the frozen zone policy.

Where to start

Not with everything at once. The book gives two rules. If one stage scored lowest on the maturity self-assessment, start there. If you are not sure, start with close-out: it is the weakest stage at most plants and the one that makes the cycle a cycle, because it feeds every future plan.

A ten-minute test from Chapter 9: pull ten close-outs from last week and count how many record parts, a failure code, readings, deviations and notes for next time. Below three, close-out is your first project. The close-out quality rubric is the standard to score against.

From the book: what changed at Kepler

From Fix the System, Chapters 6 to 9. Ray, a maintenance manager at a plant called Kepler, installed the stages one at a time. Carl, the planner, went from two complete job plans in a week to ten to twelve once his planning time was protected. Schedule compliance rose from 65% to 82% after 90 days of the scheduling installation and 89% at six months. Close-out quality went from 14% to 82% in 180 days. Wrench time went from 36.5% at baseline to 51% after the identify, plan and schedule stages, and 58% after the execution stage. Same twelve mechanics. No added headcount.

Why planning and scheduling break down

The planner never plans. Breakdowns, vendor calls and meetings eat the week. The fix is protected calendar time and an escalation chain, not another planner.
The schedule is loaded to headcount. Leave, training and meetings were never taken out, so the week was over-committed before it started.
The Monday schedule dies on Tuesday. No reserve, no frozen zone and no break-in rule, so every request rewrites the week. Diagnose it with why weekly maintenance schedules fall apart.
Work never reaches the system. Requests live in radio calls and hallway conversations. See maintenance requests outside the CMMS.
Close-outs say "Repaired. RTO." The next plan starts from nothing, and the same job is estimated wrong again.

Questions planners ask

What is maintenance planning and scheduling?

The process that prepares maintenance work before it reaches the floor (planning) and commits it to specific days, crews and production windows (scheduling). Together they decide how much of a crew's paid time turns into finished work.

What is the difference between maintenance planning and scheduling?

Planning answers how and with what: scope, parts, procedure, hours and safety. Scheduling answers when and who: the committed weekly schedule, agreed with operations and frozen before execution.

Which KPIs measure planning and scheduling?

For planning: share of work with a written job plan (over 75%) and planner time spent planning (60% or more). For scheduling: schedule compliance (over 85%) and break-in work (under 15%). Downstream, wrench time shows whether both are working. All of them are in the 12 maintenance KPI examples.

Do you need planning software to do this?

No. The book installs each stage with a template, a meeting and a management decision. A CMMS helps hold the schedule baseline and the close-out record, but the discipline comes first.

How long does it take to install?

The book sets a 90-day installation for each stage and installs them one after another. At Kepler, the scheduling stage was the fifth month of the overall plan, because close-out and identification went first.
