According to ISO 26262, an impact analysis must be performed at the beginning of a project to identify work products that can be tailored, provided the project is based on a predecessor project. Differences between the two projects are assessed with respect to the following three categories:
- Changed requirements;
 - Revised design; and
 - New integration environment.
 
In this episode, we will not only introduce the method itself, but also explain why an impact analysis makes sense not just at the beginning of a project.
