How do you derive software requirements?
Derived requirements
- Partition the system (model) into elements (for example, using OOAD methods).
- Determine how these elements collaborate to yield the desired system behavior.
- Aggregate the lower-level behaviors from the collaboration to yield the element-level requirements.
Do 178C derived requirements?

The major differences between DO178B and DO178C could be categorized in the following ways: Error and Inconsistencies: DO178C addressed the known errors or issues from DO-178B/ED-12B. Objectives and Activities: DO178C refined the objectives and activities. There are also additional objectives for Level-A software.
