Advanced driver assistance systems (ADAS) and autonomous functions in modern vehicles introduce new risks beyond classical functional safety. No-fault hazards and unknown usage scenarios make it imperative that systems are evaluated for SOTIF.
In this context, the ISO/PAS 21448 standard has been developed to complement ISO 26262. Optival provides the following services by offering analysis, evaluation and testing strategies within the scope of SOTIF in a systematic structure:
SOTIF Training and Awareness Programs
SOTIF involves a new safety paradigm that not only system engineers but also concept development, testing, algorithm development, driving simulation teams and managers need to understand together. Optival offers specially structured SOTIF training programs for different disciplines.
Types of Education
Basic Level Trainings (Awareness & Introduction)
- Scope and purpose of ISO/PAS 21448 and its relationship with ISO 26262
- SOTIF concepts: Acceptable and unacceptable risk
- Unknown scenario concept and sources of danger
Target Audience: All technical team, business development, project managers, quality and strategy units
Engineering Focused Trainings
- Analysis of algorithm, sensor and software risks
- Triggering Condition, Causal Factor and Hazard Relationship Model
- SOTIF test strategies: simulation, usage profile, edge-case testing
Target Audience: Algorithm developers, system/software engineers, test teams
Project Based and Applied Trainings
- SOTIF analysis process over real ADAS functionality
- Generating hazard scenarios and risk classification
- SOTIF verification plan and test integration
Target Audience: Project teams, technical leaders, system security experts
- On-site face-to-face training
- Live online sessions
- Turkish, English or German language options
- Post-training evaluation and certificate of attendance/success
- Trainer staff offering both technical content and practical experience
- Functional safety approach integrated with automotive homologation processes
- Customized training content according to project needs
- Sustainable competency development with post-training consultancy
GAP Analysis and SOTIF Process Setup
ISO/PAS 21448 requires a restructuring of the development culture and test strategy, not just for a specific product.
Optival takes the following steps to embed SOTIF processes at the corporate level:
GAP Analysis: See Your Compliance Level
- Identification of functions covered by SOTIF and possible gaps in existing systems
- Comparison of organizational responsibilities and testing strategies with SOTIF
- Risk classification method, event chain analysis, evaluation of verification strategies
FSM Setup: Build Your Process Infrastructure
- Establishing SOTIF security policy, workflow and responsibility structure
- Defining templates for work products such as SOTIF hazard record, SOTIF assessment report
- Integrated and sustainable building construction with functional safety
Hazard Scenario Development and Risk Classification
Unlike classical fault-based risk analysis, SOTIF addresses system behaviors that may pose a hazard even without a fault.
Optival provides systematic hazard generation, triggering condition identification and acceptability assessment.
- Identification of possible scenario sources (sensor errors, missing training data, environmental conditions)
- Modeling error-free but dangerous situations
Risk classification and recommendation of safety enhancing measures
Determination and Implementation of Testing and Validation Strategy
Verification under SOTIF consists not only of classical testing, but also of strategic testing such as system behavior testing under unexpected conditions targeting critical scenarios, real environment and simulation testing.
Optival determines the test and verification strategies that are appropriate to the test requirements and supports their effective implementation.
Audit and Certification Support
Although there is no formal certification for SOTIF compliance, technical assessment and standard compliance reports prepared for customers or authorities are requested.
Optival supports the preparation of project-specific documents such as SOTIF assessment report, risk assessment files, test and verification records.
