Acceptance Criteria, Validation Targets and Performance Targets in an ISO 21448 Conform Development Process

This thematic paper presents an approach of handling Acceptance Criteria and Validation Targets within an ISO21448 conform development process for highly automated driving functions. This includes an approach for breaking down Acceptance Criteria from global level to scenario class level. Furthermore, the application of Validation Targets for the respective Acceptance Criteria is addressed while the underlying methods for definition are briefly described. In order to support efficient development on component level and to avoid premature testing, quantitative Performance Targets are introduced functioning as quality goals for integration and testing on higher engineering levels.
