Software Safety and Risk Management Training Workshop

Software Safety and Risk Management Training Workshop is a 3-day hands-on workshop focusing on software safety, software hazards analysis principles and techniques, hazards identification, critical thinking, risk assessment in terms of severity, probability and control, risk mitigation.

Course Description

Software requires special attention in system planning, architecture, design, verification, validation and test.  Software Safety and Risk Management Training Workshop presents techniques and methods of developing and analyzing software and highlights managing a software safety program,  problem solving, solutions and safe designing, FMEA, FMECA, FTA, and FRACAS applicable to software, related system and hardware, embedded systems and firmware.

Software design principles will be taught to create programs that are fault tolerant and acceptably safe.  Several software hazard analyses methods will be evaluated, including Fault Tree/Soft Tree, Software Sneak Analysis and Petri Nets.

Workshop Objectives:

  • Learn the key concepts of software safety, hazards, root causes, risk assessment, risk mitigation,  and management
  • Discuss methods to discover, control and prevent software hazards
  • Recognize various software safety program administrative methods, modeling, management and documentation
  • Build and develop safe software  free of imperfections causing unsafe conditions in safety-critical systems
  • Learn about risk assessment in terms of severity, probability and control
  • Discuss risk mitigation techniques and tools, problem solving/solutions and safe designing

Who Should Attend

Software  engineers and managers, system safety engineers, embedded software engineers who are involved with developing systems that possess major software components.
