Reactive Work Two-Week Audit Sheet

Letter & A4. Print-ready. Free, no email required.

Two weeks. Every incoming WO. Classified against the four-question rubric, not against gut feel. The classified sample tells you where the reactive work is actually coming from.

Companion to: Fix the System, Chapter 18. Who uses it: the planner and maintenance supervisor, together. One of them runs intake; the other audits the classification after the fact. When: days 1-14 of the install (baseline). Re-run at day 60 (verification). Re-run quarterly after stabilization. Why this exists: plants measure reactive work as a single percentage and stop there. The percentage is a sum of four very different things: true emergencies, preventable failures, pseudo-emergencies, and operator-environment calls. The audit separates them so the install attacks the real top cause, not the average.


Step 1 — Prepare the audit

Before day 1:

  • Print the four-question intake rubric and laminate copies for the planner, the supervisor, and the CMMS intake screen.
  • Calibrate the rubric with the maintenance supervisor on 10 recent WOs before the audit starts. Walk through each one out loud. Alignment on day 0 is the biggest predictor of a clean audit.
  • Confirm the audit window (14 consecutive days) and brief the shift supervisors that every incoming WO will be classified — they do not need to do anything differently, but they should expect questions.

Step 2 — Run the intake rubric on every incoming WO

For 14 consecutive days, every incoming WO goes through the four-question test at intake. Record the answers on this sheet (or a CMMS field if available).

The four-question rubric

Q1. Did this failure put the plant, a production line, or a person in immediate danger? (Y/N)

Q2. Is this failure preventing operation right now, with no duplicate capacity available? (Y/N)

Q3. If this work waited 48 hours, would it cause safety, environmental, or regulatory exposure? (Y/N)

Q4. Was this condition detectable 7 or more days ago via inspection, condition data, or operator observation? (Y/N)

Classification rule

  • Any YES to Q1, Q2, or Q3TRUE EMERGENCY. Legitimate reactive work. Break-in process (Chapter 10).
  • YES to Q4 onlyPREVENTABLE REACTIVE. The condition was detectable earlier. Flag for PM/CBM feedback.
  • YES to Q1-3 AND YES to Q4 → both flags apply: true emergency AND preventable. Log in both buckets.
  • NO to all fourPSEUDO-EMERGENCY. Not reactive. Goes into the regular backlog.
  • Operator-environment WO (sanitation, setup, production-driven request) → log as OPERATOR-ENVIRONMENT, separate from the reactive taxonomy.

Step 3 — Audit log

Fill one row per incoming WO. Add pages as needed.

WO #DateShiftZone / lineAssetAs-entered priorityQ1Q2Q3Q4HoursTrue classification

(Extend as needed — expect 40-80 rows for a 14-day audit on a typical 150-asset plant.)

True classification values: TRUE EMERGENCY / PREVENTABLE / BOTH / PSEUDO-EMERGENCY / OPERATOR-ENVIRONMENT / PLANNED (Q1-4 all no AND no urgency claim)


Step 4 — Tally

BOTH (urgent AND preventable)
PSEUDO-EMERGENCY

PLANNED (non-reactive)
TOTAL100%

Reactive total (true + preventable + both + pseudo + operator-environment) = ________ %


Step 5 — As-entered vs true priority mismatch

For every WO where the as-entered priority differed from the rubric-assessed true priority, log the mismatch.

WO #As-enteredTrueDirection (inflated / deflated)

Mismatch rate = ______ % of audited WOs

Healthy: <20%. Concerning: 20-40%. Action: >40% (the escalation culture is strong).

Most mismatches in a plant running above 40% reactive are INFLATED — the operator called it an emergency when the rubric says it is not. Deflated mismatches (real emergencies called routine) are rare but dangerous; investigate each one.


Step 6 — Top-cause analysis

Rank the classification categories by hours consumed, highest first. Pick the top one (by hours) as the primary target for the day 14-60 attack.

Attack channel values:

  • PREVENTABLE → PM procedure update / CBM install / frequency adjustment
  • PSEUDO-EMERGENCY → supervisor retraining / weekly metric share / intake rule enforcement
  • OPERATOR-ENVIRONMENT → SOP change / operator training / environmental fix

Step 7 — Zone breakdown

If the audit covered multiple production lines or systems, break out the reactive percentage by zone.

Zone / lineWO countReactive hoursTotal hoursZone reactive %

Look for zones significantly above the plant-wide average. Those are the real install targets — the plant-wide number hides them.


Step 8 — Sign-off

What to avoid

  • Running the audit for less than 14 days. Shorter windows miss the weekly cycle of production-driven calls.
  • Letting the operator classify. The maintenance group classifies against the rubric. Operators can flag urgency; they do not set it.
  • Skipping the zone breakdown. A plant at 22% plant-wide with one line at 47% needs the zone-level attack, not the plant-wide one.
  • Picking more than one top-cause attack. Three attacks at once collapse the install discipline. One per quarter.
  • Treating pseudo-emergency as cultural, therefore unfixable. The culture is a lever, and it is the single biggest one. Attack it.
