Case Study Example 3.6 (Scoring & Feedback) |
||
|---|---|---|---|
Scoring & Feedback: To obtain a concise measure of the KSB from the checklist responses, the Behavioural Safety Index formula (Komaki et al, 1978) was used. This divides the number of safe observations by the total number of safe and at-risk observations, multiplied by 100 . Checklist responses were entered into spreadsheets that automatically calculated the safety percentage by applying the BSI formula to the data entered. A collective safety percentage was established on a weekly basis over the four-week observation baseline period (See Figure 3 for weekly BSI). These safety figures (combined to ensure anonymity of individual operatives) were fed back to all operatives via weekly toolbox talks. The manager in the steering team also provided feedback to the rest of the managers at their monthly manager operations review meetings. The checklists used in the present programme involved only one count of each unsafe act per day (i.e. frequency of an unsafe act was not recorded). This was to simplify the observation process and, due to hazardous operations, operatives completed their checklist at the end of the shift, by which time it may be difficult to recall the accurate number of times the unsafe act had occurred. |
