(Paper Review) Effective Management of Functional Safety for ISO 26262 Standard


I recommend this paper for a person in a management level who want to find a functional safety manager, or a person who want to be a functional safety manager.

If you read this paper, you will understand why functional safety compliance is very hard to achieve. Role of functional safety manager is not a safety engineering, but it seems to be common for most untrained persons or persons who has little knowledge for a functional safety have in mind that safety engineering is not related to themselves and it should be covered by a functional safety manager.

If a top level manager also has a similar concept, it would be a big deal to comply a functional safety standard.

In the paper, an author suggests that functional safety manager should be able to have roles in the below

  1. Project/Safety manager – To plan and control. Manage PDCA cycle
  2. Requirement Manager – To manage/establish a scheme that have much convincing.
  3. Configuration Manager

I agree also, and these activities are not engineer’s interest and if nobody takes these kinds of role, then it is not easy to defense against customer audit.

Anyway, it is well written paper. Highly recommended.
