Functional Safety:-

Security :-

  • Deals with the protection of person or system against external hazarads
  • focuses on risks emerging from the functions of a device /system
  • It does not focus on risks like fire or environmental pollution
  • Functional safety is the part of the overall safety of a system or piece of equipment that depends on the system or equipment operating correctly in response to its inputs, including the safe management of likely operator errors, hardware failures and environmental changes

· Organization Process Definition supports the management of processes -

· It establishes and maintains the descriptions of the lifecycle models that are approved for the use in the organization.

· It establishes and maintains tailoring criteria and guidelines for the organization's set of standard processes.

  • Safety Culture
  • Quality Management
  • Continuous Improvement
  • Training and Qualification
  • Processes for risk analysis design,development, verification and validation
  • Methods and techniques to be applied depending on the SIL level (eg, walkthroughs, inspections, diverse programming, error detecting codes, black box testing, error seeding)
  • Functional safety assessment (providing evidence)
  • Functional safety address more the engineering however ,an active and alive CMMI culture strongly facilitate implementation of such standard evn outside engineering
