Metrics Glossary
This page defines the key metrics used across the Continual portal, including how each is calculated. Unless otherwise noted, all metrics are calculated over the selected factory and date range.
Check Execution Metrics
Due
Definition: The total count of check instances that were scheduled to occur during the selected period.
This includes instances in all terminal and in-progress states: completed, missed, skipped, and pending (if still within the period).
Completion Rate
Definition: The percentage of check instances that were completed out of all instances that were either completed or missed.
Completion = Completed ÷ (Completed + Missed) × 100Skipped instances are excluded from both the numerator and denominator, since a skip is a deliberate decision rather than a failure to act.
Compliance Rate
Definition: The percentage of completed check instances that passed, out of all completed instances that had a pass/fail result.
Compliance = Passed ÷ (Passed + Failed) × 100Checks without a pass/fail result (e.g., photo-only checks) do not contribute to this metric.
Timeliness Rate
Definition: The percentage of completed check instances that were submitted before the grace period ended.
Timeliness = On-time completions ÷ Total completions × 100A completion is "on time" if completed_at ≤ grace_period_end_at.
This metric appears on Analytics → Insights → Completion as the schedule timeliness section, alongside a breakdown of how late completions were (on time, 1–3 hrs late, 3–8 hrs late, 8+ hrs late).
Time on Task (Median)
Definition: The median elapsed time from when an operator taps Start on a check to when they submit the result, calculated over timed completions in the selected period.
Only completions recorded via the mobile app with an explicit Start action include timing data. The Completion insights page also shows coverage (what share of completions were timed), a distribution histogram, daily median trend, and per-check typical times in the breakdown table.
Quality Metrics
CIL Defects
Definition: The count of defect actions automatically created from failing CIL checks during the period.
One action is created per failing CIL check. If the same check fails multiple times while its action is still open, the failure count on the action increments rather than creating a new action.
CIL MTTR (Median Time To Resolution)
Definition: The median elapsed time between when a CIL defect action was created and when it was resolved (moved to pending verification or closed).
MTTR is expressed in hours. The median is used rather than the mean to reduce the influence of outlier actions that stay open for extended periods.
A lower MTTR indicates that defects are being addressed faster.
Deviations
Definition: The count of deviation actions automatically created from failing centreline check results during the period.
A centreline check fails (and a deviation is created) when the submitted value falls outside the configured target range.
Deviation MTTR
Definition: The median elapsed time between when a deviation action was created and when it was resolved.
Deviations frequently auto-close when the next check passes, so their MTTR is typically much shorter than CIL MTTR.
Production Metrics
OEE (Overall Equipment Effectiveness)
Definition: Total actual output divided by the theoretical maximum output on days where output data was recorded.
OEE = Actual output ÷ Maximum possible output × 100Maximum possible output is derived from the line's configured maximum rate and the operating hours in the period.
Days with no recorded output are treated as zero output against the configured maximum for that day rather than excluded. OEE is a directional indicator — its accuracy depends on consistent output recording.
Line Efficiency
Definition: Actual output divided by planned output for the period.
Line efficiency = Actual output ÷ (Maximum output − Planned downtime) × 100Planned downtime represents scheduled maintenance or intentional stoppages. This metric shows how efficiently the line operated relative to what was planned.
Proposal Metrics
Changes Proposed
Definition: The count of check change proposals (modifications or new check creation proposals) submitted during the period.
Proposals Accepted Rate
Definition: The percentage of reviewed proposals from the period that were approved.
Accepted = Approved proposals ÷ (Approved + Rejected) × 100Pending and invalidated proposals are excluded.
A Note On Date Scoping
All metrics are scoped to the due date of the check instance, not the completion date. A check that was due yesterday and completed today is counted in yesterday's metrics.
Instances that were scheduled within the period but are still pending (not yet past their grace period) are included in the Due count but do not yet contribute to completion or compliance.
