OEE Rapid Diagnosis Workbook

Interactive workbook frontline teams can use during or immediately after a shift to validate OEE inputs, capture the top losses (availability, performance, quality), run quick 5‑whys, triage priorities, and define one prioritized experiment to run next shift. Saves a structured submission for follow-up and aggregation.

OEE Rapid Diagnosis Workbook

OEE Rapid Diagnosis Workbook

Use this workbook during or immediately after a shift to validate OEE inputs, capture the largest losses, run a short 5‑whys, and define a single prioritized experiment for the next shift. Fill what you can — required fields are marked. If your MES or historian can pre-fill counts and times, use those values to improve accuracy.

Short coaching script for the shift review

Supervisor: "Two-minute huddle — this was our top loss, here's what we contained, likely root cause, and the experiment we'll run next shift. Who owns it and what will you measure?" Capture commitments in 'Follow-up actions'.

Enter the shift date. Use ISO format to help aggregation.
Select the shift.
Where this workbook applies.
Name(s) of operator(s) on shift.
Total planned production minutes for the shift (scheduled time minus planned breaks).
Planned non-production time included in the schedule.
Total unplanned stoppages observed during the shift. Use loss capture details below for specifics.
Planned production time minus planned breaks minus unplanned stopped time. Validate this number.
Standard cycle time per good part (seconds).
Total pieces produced (good + scrap) during operating time.
Number of acceptable parts. If unavailable, estimate and mark confidence below.
Optional: Availability = Operating time / Planned production time × 100. You may fill if calculated elsewhere.
Optional: Performance = (Ideal cycle time × Total count) / Operating time (convert units) × 100.
Optional: Quality = Good count / Total count × 100.
Optional: OEE = Availability × Performance × Quality (expressed as percent).
How confident are you in the numbers above? 1 = low, 5 = high.
1.0 10.0
Choose how many individual loss lines you will fill below. Use the most significant losses first.
Approximate minute within the shift when the loss began (0 = shift start).
Duration of this loss event in minutes.
Describe what happened (one or two sentences).
What was done to continue production or limit damage?
List up to five 'why' steps or a short root-cause summary.
Estimated minutes lost attributable to this event.
If quality loss, estimate scrap count attributable to this event.
Use quick triage to choose focus.

Check the loss(es) you plan to act on. Prefer 1–2 items.
Person responsible for running and reporting the experiment.
Describe the quick change, containment improvement, or test you will run next shift. Keep it small and observable.
Example: reduce repeat stops from X to Y, save Z minutes, reduce scrap by N parts.
Example: shift log, MES counter, sample check every hour.
How many shifts will you run the experiment before review?
Short notes from the shift huddle. Who committed to what?
Capture commitments and dates. Useful for handover to CI or next shift.
Choose Yes to notify CI or save for local review.
