Why ‘Safety Plan’ is Critical in Development of ISO 26262 Complaint Product and Automotive Functional Safety ? Based on experiences in software development projects, a product development team may opt for various different approaches of SDLC. One of such proven approaches is Plan-Do-Check-Act, a general practice followed during project planning, especially in compliance verification scenario. • • • •

PLAN– Development Interface Agreement, Safety Plans DO– Concept documents, analysis documents, software codes CHECK– any form of validation like MISRA C and other audits, ACT– on preventive actions based on the derivations from Check stage.

With ISO 26262 coming into the picture, one more dimension called safety planning has become a critical part of such project management planning (PLAN-Do-Check-Act). ISO 26262 mandates that the organization that wishes to implement functional safety in automotive software development, needs to follow a well-defined safety culture. Embitel Technologies

What Goes into ISO 26262 Recommended Functional Safety Plan Creation and Execution?

Safety planning management is concerned with the execution as well as the documentation of each and every safety related activity. We will discuss these activities in detail and see how are they executed and documented. 1. Organization Structure in Functional Safety Planning Achieving functional safety in the automotive software development needs all the stakeholders to work towards this common goal. The interaction among the project team members needs to be defined in the safety planning activity sheet.

2. Project Safety Lifecycle as Recommended by ISO 26262 ISO 26262 document provides a product lifecycle diagram that needs to be referred to while creating the safety plan. One may not use the full diagram in every project as each project may have different scope. For instance, concept development and hardware design may not be the part of the project. Hence, we need to mark those areas that come under the scope of the particular project.

3. Development Interface Agreement (DIA) DIA is an elaborate sheet that depicts all the work products for the service provider, OEM and the vendor. It is easy to understand it by considering three entities as the stakeholders of the project, as mentioned before- OEM, Vendor and Service provider.

4. Automotive Functional Safety Techniques and Measures to Achieve Applicable ASIL The analysis of software and hardware required in the project needs due diligence. If you look at part 6 of the ISO 26262 documents, several tables are provided that shows the methods and techniques for hardware and software analysis. The method to be chosen for this analysis is also decided based according to these tables. The following is one such table.

4. ISO 26262 Mandated Safety Audits & Assessments The frequency of audits by internal safety assessment team can be decided by the safety manager or the project manager. The assessment can be done by internal teams but audit is usually carried out by external agencies, especially when certification is required.

The Final Thoughts

Functional Safety compliance is different from other QAs like CMMI etc. It deals with very specific functional area and requires certain skills and qualifications. Moreover, achieving functional safety in automotive software development is evidence based. These are some of the reasons why safety planning becomes a crucial part of ISO 26262 compliance. The blog touches upon all major aspects of safety planning management as recommended by Part-2 of ISO 26262 guideline.
