Downtime and Scrap Shift Log

Logs each downtime event with start/end time, duration, and reason code alongside scrap counts by reason so losses can be Pareto-analyzed by production line and shift.

Shift Identification

  Date the shift occurred (not the date of submission).
• Shift
• Production Line / Cell
• Shift Supervisor Name
• Log Completed By
• Planned Production Time (minutes)
  Total scheduled run time for this shift, excluding planned breaks. Used to calculate OEE availability.

Downtime Events

• Downtime Event Log
  Add one row per downtime event. Start and end times should be in HH:MM (24-hour) format entered as text. Reason codes follow SEMI E10 / internal standard categories.
• Total Downtime This Shift (minutes)
  Sum of all downtime event durations above. Enter manually; used to cross-check individual entries.
• Additional Downtime Notes

Scrap and Defect Log

• Scrap Event Log
  Add one row per part number / defect reason combination. Do not aggregate different defect types into a single row.
• Total Scrap Units This Shift
  Sum of all scrap quantities above. Used to calculate OEE quality rate.
• Total Rework Units This Shift
  Sum of all rework quantities above.
• Is a Quality Hold currently active on this line?
• Quality Hold Details

Production Output Summary

• Good Units Produced (accepted output)
• Total Units Started / Attempted
  Good units + scrap + rework started. Used to calculate first-pass yield.
• Shift Production Target (units)
  Planned output for this shift based on the current production schedule.
• Number of Changeovers / Product Switches

Shift Close-Out and Sign-Off

• Open Issues / Action Items for Next Shift
• Was a Maintenance Work Order raised this shift?
• Work Order Number(s)
• I confirm that all downtime durations, reason codes, and scrap counts recorded in this log are accurate to the best of my knowledge.
• Flag this log for supervisor review?
  Select Yes if any event this shift requires management attention beyond normal handoff.
