|Applying assessments with the "gut feelings" tool and not SPC, is ineffective assessment.|
A Safety Policy as a regulatory requirement is described to conform to regulatory requirements and when implemented in the organization, the regulatory requirements are met. An assessment of this safety policy could conducted by anyone, and the result, or opinion of the ability of SMS, would change with the assessor's background and experience. Unless factual data and Statistic Process Control (SPC) is applied in assessment for effectiveness , the assessment is subjective and the outcome becomes irrelevant to safety.
A safety policy is not effective just because reports are received, investigated filed and completed. The policy is effective when an SPC analysis shows that the goals of the policy were met, that the objectives were met and the policy itself has an effect on human factors in the organization for a desire to achieve an undisputed safety record.
|Data applied in SPC is discovering the variables of a flowing river.|
Without applying SPC in assessments, data collected becomes subjective, while data itself respond only to objective assessments. Subjective assessments do not affect data in the way that a change in processes makes a difference in desired outcome. The change of outcome will simply change because the process was changed by a subjective evaluation, and without regards for an objective desired outcome. When disregarding objective data available and applying a subjective, or "gut feeling" opinions to data, the changes could have been made without the implementation of a Safety Management System.
