Requirements Engineering Workflows

For a detailed explanation of workflows and their role within the process model, please refer to the Introduction.

Stakeholder requirements and SW-Platform Assumptions of Use (AoU) can be created during a change request. Any contributor can create a stakeholder requirement (or AoU) and propose it for approval.

Depending on the stakeholder requirements feature requirements can be derived. This can be done by any contributor and will be approved by a project lead. If needed safety and security managers can provide support.

Based on the safety concept on feature level, feature AoUs can be derived. See also Workflow for Creating and Linking Assumption of Use (AoU)
