Multi-site dashboards: compare definitions before comparing percentages
A cross-site completion dashboard needs consistent definitions of scheduled, completed, missed and unresolved work. A single percentage can hide differences in schedules, applicable checks and open findings between sites.
At a glance
A cross-site completion dashboard needs consistent definitions of scheduled, completed, missed and unresolved work. A single percentage can hide differences in schedules, applicable checks and open findings between sites.
Define the decision behind the record
Decide what the comparison is intended to support. Separate completion from results and corrective actions. Document how cancelled tasks, local variations and late entries affect the figures instead of leaving managers to infer the denominator.
Compare denominators and exception status before percentages
Define what counts as required, completed, late, missing and not applicable for each reported period. Identify site scope and relevant template versions. Equal displayed percentages may describe different numbers of observations or different task boundaries.
Retain the underlying counts and make unresolved exceptions or decisions visible alongside completion. For example, 18 of 20 and 9 of 10 both equal 90%, but do not establish the same coverage. Separate submission status from implementation and verification rather than combining them into a single reassuring indicator.
Test the dashboard with one site using a local variation and another with complete submissions but an open decision. A reviewer should trace the summary back to its source definitions and records. Preserve changes in reporting logic so a trend does not silently compare measures that changed meaning.
Worked example
Two sites display the same completion percentage, but one has a recorded exception awaiting review. The dashboard separates the scheduled-work count from open findings so the comparison does not imply identical operational conditions.
Build a usable record
Use the fields below to capture the facts needed for this particular decision. Keep the actual observation separate from any later correction or approval.
- Site and reporting period
- Scheduled and applicable task definitions
- Completion and late-entry treatment
- Exceptions and open actions
- Local variations and limitations
Example record and review decision
Fictional record example: SITE-A: 18 of 20 required checks; SITE-B: 9 of 10; both report 90%, with separately listed misses and open decisions.
Compare definitions, denominators, periods and exception status before interpreting equal percentages.
Identical percentages do not establish equal coverage or equal unresolved risk when task scopes differ.
Test the review, not just the form
Reproduce one displayed figure from the underlying records. Compare its definition across sites and check how a schedule change affects historical reports. Do not equate a higher score with a lower risk without an appropriate basis.
A few useful answers
Does a completion percentage measure safety?
It measures the defined completion status. Interpret it alongside results, unresolved issues and the relevant assessment process.
Does an equal percentage mean equal performance?
It establishes a numerical relationship under each definition. Compare scope, denominator, time period and unresolved work before drawing an operational conclusion.
