Monitoring achievement. The indices of achievement in Figure 7.3 are generally more difficult to record and track than those in Figure 7.1. Actually, the failure outcomes in Figure 7.1 are observed and recorded quite naturally. Except for near hits and first-aid cases, the failures in Figure 7.1 have traditionally resulted in systematic investigation and formal reports. In contrast, the achievements in Figure 7.3 are somewhat difficult to define and record. In fact, it is impossible to obtain an objective record of the number of injuries prevented. A reasonable estimate of injuries prevented can be calculated, though, after you achieve a consistent decrease in injuries as a result of a proactive, behavior-based process.
