Designing KPIs That Show Whether Your Management System Works
How to design indicators that show whether processes and the management system are really performing
Key takeaways
- ISO 9001, ISO 14001, ISO 45001 and ISO 22000 all require monitoring, measurement, analysis and evaluation (clause 9.1): what to measure, how, when, and when results are analysed.
- Good KPIs are linked to objectives and process purpose, have a clear definition and formula, a target, an owner and a data source.
- Each process should have a small number of meaningful indicators, mixing outcome and process measures.
- Trends matter more than single values; targets without analysis add little.
- KPIs should drive decisions at process reviews and management review.
1. From “we measure many things” to useful KPIs
Many organisations collect dozens of numbers that nobody uses, while missing the few that matter. The standards do not ask for a long list. They ask the organisation to decide what needs to be monitored to know whether processes achieve their intended results and whether the management system is effective.
2. Characteristics of a good KPI
| Characteristic | Question |
|---|---|
| Relevant | Does it show whether the process achieves its purpose or objective? |
| Defined | Is the formula clear, including what is counted and excluded? |
| Measurable | Is the data reliable and available on time? |
| Owned | Who is responsible for the result and for action? |
| Targeted | Is there a target or acceptable range, with a reason? |
| Actionable | Can the owner influence it? |
| Reviewed | When and where is it analysed? |
3. Outcome and process indicators
| Process | Outcome indicator | Process (driver) indicator |
|---|---|---|
| Sales and contract review | Orders delivered in full and on time (OTIF) | % of orders with complete specification at entry |
| Production | First pass yield | Planned maintenance completed on schedule |
| Purchasing | Supplier nonconformities per 100 deliveries | % of critical suppliers evaluated this year |
| Customer service | Complaints per million units | Average time to first response |
| HR and competence | Errors attributed to training gaps | % of staff with valid competence for their role |
| Internal audit | Repeat findings | % of audit programme completed |
| Environment | Energy per tonne of product | % of energy-saving actions completed |
| OH&S | Lost-time injury frequency rate | Near misses reported per 100 workers |
Outcome indicators show results; process indicators show whether the conditions for good results are in place.
4. KPI definition sheet
For each KPI, record:
- Name and purpose.
- Formula, unit and data source.
- Frequency of measurement and reporting.
- Target and justification (customer requirement, past performance, benchmark).
- Owner.
- Trigger for action (e.g. two consecutive months outside target).
- Where it is reviewed (process meeting, management review).
This sheet avoids arguments about how a number was calculated.
5. Analysing and using results
- Plot trends over at least 12 months, not just month-to-month comparisons.
- Look for patterns: shifts, cycles, outliers.
- Compare against targets and against similar processes or sites.
- When a KPI is off target, ask why, using root cause analysis where needed, before setting actions.
- Retire indicators that no longer help decisions.
6. Linking to objectives and management review
Objectives (clause 6.2) should be measurable; their KPIs show progress. Management review uses KPI analysis to decide on improvement, changes and resources. If management review minutes contain no decisions based on indicators, the measurement system is not working.
7. Common weaknesses
- Too many indicators, none analysed.
- KPIs without formulas, so results change depending on who calculates them.
- Targets set once and never reviewed.
- Only outcome indicators, so problems are seen too late.
- KPIs reported but not linked to decisions or actions.
Conclusion
A small set of well-defined KPIs for each process, analysed as trends and used in decisions, is the clearest evidence that a management system is effective. It also gives managers the early warning they need to act before customers, regulators or auditors notice a problem.
Take one process and write its KPI definition sheet. If you cannot write the formula, the KPI is not ready.
