Safety Work Product

Definition

Safety Work Product

a work product produced during the safety engineering activity

Safety Work Product Set

the work product set consisting of the cohesive collection of all safety engineering work products

Work Products

The OPF repository contains the following set of predefined safety work products:

• Accident_Frequency_Categorization,
  which categorizes accidents in terms of the maximum frequency that they may occur and which categorizes hazards in terms of the maximum frequency that they may cause an accident to occur.
• Accident_Severity_Categorization,
  which categorizes accidents in terms of the severity of the harm they cause and which categorizes hazards in terms of the maximum severity of the harm their associated accidents may cause.
• Hazard_Cause_Tree,
  which is a fault tree that shows the ways that hazardous events can lead to a hazard.
• Hazard_Effects_Tree,
  which is an event tree that shows the ways that a hazard can cause accidents.
• Incident_Investigation_Report,
  which reports the results of the investigation of an incident.
• Safety Case,
  which provides an argument for the safety of the system, application, or component.
• Safety_Certificate,
  which certifies the success of the safety program.
• Safety_Compliance_Report,
  which reports the results of analysis and assessment of the success of the safety program.
• Safety_Compliance_Repository,
  which stores all safety related information.
• Safety_Policy,
  which formally documents an endeavor’s policy regarding safety.
• Safety_Program_Plan,
  which formally documents an endeavor’s plans for implementing its safety program.
• Safety_Risk_Analysis_Report,
  which is the report that documents the results of the safety risk analysis task.
• Safety_Risk_Categorization,
  which categorizes the safety risks associated with accidents and hazards in terms of accident hazard indices and safety assurance levels.
• Safety_Status_Report,
  which documents the status of the safety program.

Guidelines

• Different endeavors require different processes, which in turn will require different safety work products.
• Every endeavor does not require the production of every safety work product.
• Select only those safety work products that are appropriate for the endeavor.
• Selected safety work products should be:
  • Relevant.
  • Useful.
  • Usable.
  • Cost-effective.
