Main Description

In this task, the requirements from previous/upper abstraction level are refined and complemented to this abstraction level. This means that some assumptions on the design of this abstraction level are made. Typically the requirements introduced or refined in this work task are later refined and/or formalized when the design has been made. For functional safety, the functional, technical, hardware or software safety requirements are introduced in this work task and allocated to the design and detailed in later work tasks, thus creating the functional/technical safety concept or being part of the hardware/software design. The refined and introduced requirements are also validated. This means that the requirements are checked to be consistent and corresponding to the actual expectations (intended requirements) of the stakeholders.
