Digitalization of Functional Safety in a Connected Supply Chain

Concerns• ISO 26262 requires not only system, hardware, and software teams of the organization to be in
Synch, but also all the affected suppliers. Change in one requirement or safety goal affects the entire distributed development.
• The requirements, HARA, Safety Goal, safety Requirements, System Design, Testing, DFMEA, Hardware Design, Testing, Software Design and Testing, and Supplier System, hardware and components safety requirements, testing, HIS are all linked. How to accomplish this without web based software tools?
• Not only should the Functional Safety tools be linked, but it needs to be integrated into the overall requirements: the DVP&R, DFMEA, PFMEA, Control Plans and Shop floor controls.
• How do we track this development from an overall management? While we have gained great experience in managing APQP/PPAP, how do we manage the Safety Plans in System, Hardware, Software and the supplier DIA including the safety case of the System.

Keeping a Functional Safety Project in Synch
(C) Omnex Systems 2018
This requires coordination of design and manufacturing in our Global Customers with the tremendous exchange of information, forms, and checklists.
How do we keep this project with Tier One with three internal development groups and 6 Suppliers in Synch?

• How do we keep Safety Plan Versions aligned?
• How to link Key Deadlines – System Testing timing, Hardware and Software timing which are dependent on each other. Other timing linked to each other
• Release of Safety Requirement, Integration Test Plan, and related Hardware and Software Technical Requirements releases?

Manage an Overall Program
• Safety Goal and Safety Requirements have been successfully verified and validated in the Test Plan (DVP&R) of the Airbag at the Hardware, Software and integration level
• This culminate into the safety case
