Is FSM a Manager or an Engineer?


As a functional safety manager, someone focus on safety engineering while the other person focus on management. Nowadays I realize that safety engineering is different from safety management and they require different technique or skills.

Safety engineering is do something for his own knowledge, while safety managing is not engineering. He makes plan and determine schedule.

In some ways, they are quite different. It would be great if a person covers both functional safety engineering and functional safety management. But I’m not such a person. I’m more close to functional safety manager than functional safety engineer.

To be a manager, managing skills are required. I think project manager can take a functional safety manager role if he study ISO 26262, but it would not be easy to be a functional safety engineer.

As a functional safety manager, I use management tools(confluence, JIRA, Polarion etc) fluently to manage. I think it is essential. But for safety engineers, it is not mandatory.

I’ve never distinguished between two roles before. Now I realize uncovered fact.

Why are you born? Meaning of safety requirement existence


If some requirement are regarded as safety attribute, it means that in-achievement of safety requirement leads to threaten safety.

The rationale is explained in the somewhere. I believe that system FTA or system FMEA are proper means of why they are born.

After they are identified, safety engineers shall suggest methods how to handle them. Their suggestions are called safety mechanisms in ISO standard.

Sometimes, engineers forget this simple principle. So non-safety related requirements are mis-perceived as safety requirements.

All safety requirements have birth-registered? Unregistered has a potential to threat safety. Don’t forget to register. It is natural like happened in our society.

How Can reuse results of the Advanced Development Project for Production Development Project when executing ISO26262 project


Can a project in production development project achieve functional safety requirements when its previous project in the advanced development project doesn’t consider functional safety ?

It is not easy to satisfy functional safety requirements in production project unless being prepared in advanced development project.

Or it will take longer than normal production project.

How to improve this situation?

We can get a hint from SEooC section in the ISO 26262-10, Clause 9

A picture below depicts SEooC development and Item development process

In general, advanced development project starts without customer, so its situation is similar to SEooC development situation. During the project many assumptions are made.

If Advanced Development Project follows like SEooC development process, Production Development Projects might reuse previous results. Additional tasks might be to compare between assumptions and requirements and to bridge gaps.
