Recent years have seen a huge increase in the use of advanced functionalities in vehicles. These rely on sensing, processing of complex algorithms and actuation by on-board electrical and/or electronic (E/E) systems.

For some systems, which rely on sensing the external or internal environment, potentially hazardous behavior can be caused by the intended functionality or performance limitations of a system that is free from the faults addressed in the ISO 26262 series. Examples of such limitations include:
- The inability of the function to correctly comprehend the situation and operate safely; this also includes functions that use machine learning algorithms
- Insufficient robustness of the function with respect to sensor input variations or diverse environmental conditions
The absence of unreasonable risk due to these potentially hazardous behaviors related to such limitations is defined as the safety of the intended functionality (SOTIF). Functional safety (addressed by the ISO 26262 series) and SOTIF are distinct and complementary aspects of safety.
Since January 2021, ISO DIS 21448 has been available as an international guideline that describes a structured recommendation on the subject of SOTIF. Especially with regard to the introduction of autonomous driving in several stages, this ISO/PAS is a valuable orientation aid for a responsible process-related and technical implementation of the new challenges.
