How Many Professionals Are Involved In Functional Safety Work?

2022-08-03

There are always, as a minimum, four professionals involved in each phase of a functional safety lifecycle. For each task, one professional does the work. One independent professional verifies the work. One sufficiently independent professional performs the assessment, and one professional manages all of this. This does not mean that each professional spends equal time on a particular task. Not each functional safety task will cost you 4x times the manpower. If you do it right, it is much less.

So four roles:

• Worker
  
• Verifier
  
• Functional Safety Assessor
  
• Functional Safety Manager
  

All these professionals need to be, of course, competent in performing their tasks. If it is a SIL Certification project, then there is a fifth role, the certifier.
