Clause 9.1.1: General
The organization sets up, runs and keeps processes for monitoring, measuring, analysing and evaluating performance.
What clause 9.1.1 asks
The organization sets up, runs and keeps processes for monitoring, measuring, analysing and evaluating performance. It decides what is to be monitored and measured (including how far legal and other requirements are met, activities and operations linked to identified hazards, risks and opportunities, progress on objectives, and how effective operational and other controls are); which methods will give valid results; the criteria against which performance is judged; when monitoring and measuring take place; and when the results are analysed, evaluated and communicated. It evaluates its OH&S performance and how effective the system is, makes sure that equipment used to monitor and measure is calibrated or verified, used correctly and properly looked after, and keeps documented information as evidence.
Monitoring has to say whether controls work and whether performance is improving, not only whether someone was hurt. Equipment used to measure has to be fit for the purpose.
Draft 9.1 Monitoring, measurement, analysis and evaluation, from clause 9.1.1. The draft contents keep 9.1 and the evaluation of compliance at 9.1.2, and replace the 9.1.1 general heading with the fuller title. No substantive change to the monitoring duties is described in the summaries held.
Evidence for clause 9.1.1
An auditor will pick a control and ask what was measured to show it worked, and check the calibration of the instrument used.
- Performance measurementMonitoring and measurement plan with methods, criteria and frequencies
- Performance measurementLeading and lagging indicator reports
- Performance measurementCalibration and verification records for monitoring equipment (noise, gas, exposure)
- Performance measurementRecords of analysis and communication of results
Where clause 9.1.1 commonly fails
- Only lagging indicators measured
- Effectiveness of controls never evaluated
- Monitoring equipment uncalibrated
What to do about clause 9.1.1 before the revision
Add a leading indicator for control effectiveness. Define the criteria and the frequency. Calibrate or verify every measuring instrument. Analyse and communicate the result, not just collect it.
What the record shows for clause 9.1.1
An auditor working on clause 9.1.1 will start with Monitoring and measurement plan with methods, criteria and frequencies. The failure this record sees most often is Only lagging indicators measured. Both are carried into the kit as row 33, with an owner field and a dated action.
