Quick answers
- What are the functional safety roles in ISO 26262?
- ISO 26262-2 turns functional safety into assigned responsibility, and in practice this settles into three core roles. The functional safety engineer builds safety into the product through the HARA, safety concepts, safety requirements and safety analyses. The safety manager plans the safety work and keeps it on track, owning the safety plan, the tailoring decisions and the safety case. The assessor, or more generally the person performing confirmation measures, independently judges work products, processes and the achieved functional safety, with independence set by the measure and the ASIL.
- What does a functional safety manager do?
- The safety manager is appointed under ISO 26262-2, Clause 6 with responsibility for planning and coordinating the safety activities of a project. The role owns the safety plan, justifies tailoring of the lifecycle, plans the confirmation measures, follows the build-up of the safety case and supports the release for production. In distributed development the manager also works through the development interface agreement that splits safety responsibilities between customer and supplier. It is a management role that still needs enough technical depth to plan and defend the work products.
Why it pays for itself
Know who does what
See the engineer, manager and assessor side by side, with their deliverables and decision power, and understand why the standard separates creating safety from managing it and confirming it.
Get independence right
Learn the four independence notations from I0 to I3 and how they apply per confirmation measure and ASIL, including the motorcycle variant in ISO 26262-12.
Plan a realistic career path
Follow a five-step route from engineer to assessor with a concrete gate at each step, and see why credentials prove competence but never independence.
What you’ll be able to do
Distinguish the three roles
Explain how engineer, manager and assessor differ in purpose, accountability and independence.
Apply independence correctly
Read the required independence for a confirmation measure and know what it means for staffing.
Staff a distributed project
Assign safety roles on both sides of a supply relationship without gaps or overlaps.
Plan your own career
Choose the next step and the evidence of competence it needs, including the move that independence requires.
