How ASIL tailoring works
ISO 26262 does not prescribe one fixed process. For each development activity it lists candidate methods, and how strongly a method is expected depends on the ASIL of the safety requirement: what is optional at ASIL A can be highly recommended at ASIL D. Choosing a lower-rated alternative is possible, but must be justified in your safety argumentation. That is why a unified view of methods and their ASIL applicability is the fastest way to plan verification and defend technique choices in a safety case.
Why a reference
Hours in the standard, or seconds in the reference.
Sound familiar?
- You spend hours in the standard trying to understand which techniques apply to your ASIL.
- Different parts describe methods in different formats, so there is no unified view.
- You need to justify technique choices in your safety case but lack a practical interpretation.
- Mapping techniques to your actual development activities feels like guesswork.
What you get instead
- Over 100 techniques in one searchable reference with ASIL A to D applicability guidance.
- Filter by topic, keyword, ASIL or method category and find what you need in seconds.
- Each technique with a detailed explanation, practical inputs and outputs, and integration guidance.
- Original applicability summaries you can use to support your safety case documentation.

Methods FAQ
Straight answers about the reference.
What it is, how the ratings read, what it covers, and why you still need the standard.
What is the methods and measures reference guide?
It is an original educational reference built by functional safety practitioners. We compiled and organized the safety engineering techniques commonly used in ISO 26262 projects, added our own interpretations of ASIL applicability, practical guidance, and real-world examples to help engineers navigate compliance more efficiently. This is not a reproduction of the standard itself.
What do the ++, +, and o ratings mean?
They follow the notation used across the industry for method applicability: "++" means the technique is highly recommended for that ASIL, "+" means it is recommended, and "o" means there is no recommendation for or against it. Our tables present our practitioner interpretation of these ratings for each technique at ASIL A, B, C, and D.
What types of safety methods are covered?
The guide covers widely recognized safety engineering techniques used across the industry: safety analysis methods (FMEA, FTA, FMEDA, STPA, DFA, Markov analysis, HAZOP), verification and validation approaches (reviews, inspections, testing strategies, structural coverage), hardware safety techniques (architectural metrics, diagnostic coverage, fault injection), and software development practices (coding guidelines, static analysis, control and data flow analysis).
How are ASIL applicability levels presented?
For each technique, we provide our interpretation of how it maps to different ASILs (A through D) based on industry best practices and the general framework of ISO 26262. The guidance helps you understand which techniques are typically expected at each integrity level for your projects.
Which areas of functional safety are covered?
The reference covers all major functional safety disciplines: safety management, concept phase, system-level development, hardware engineering, software engineering, production and operations, supporting processes, and safety analysis. Each area is organized with its own section.
Do I still need to own the ISO 26262 standard?
Yes. This reference guide is an educational companion, not a replacement for the official ISO 26262 standard. We provide interpretive guidance, practical examples, and our own structured summaries to help you work more effectively, but the official standard from ISO remains the authoritative source.
