Five Core Functions of an integrated and effective Safety Management System:

 1.    Define the Scope of Work –  Operations and missions are translated into work.  Expectations are  set, tasks are identified and prioritized, and resources are allocated.

2.    Analyze the Hazards - Hazards associated with the work are identified, analyzed, and categorized.

3.    Develop and Implement Hazard Controls -  Applicable safety standards and requirements are identified and  agreed-upon. Controls to prevent/mitigate hazards are identified, the  safety envelope is established, and controls are implemented.

4.    Perform Work within Controls -  Readiness is confirmed by management and workers.  The work is  performed safely in accordance with the established safety envelope and  controls.

5.    Provide Feedback and Continuous Improvement -  Feedback information on the adequacy of controls is collected and  reported.  Opportunities for improving the definition and planning of  work are identified and implemented.
