From requirements to verified coverage in an airborne SATCOM programme
- Situation
An airborne Ka/Ku-band SATCOM system with 4,000+ requirements across hardware, software and RF, reviewed with customers and external partners. Closing those reviews meant showing, requirement by requirement, how each one was verified. The software team worked in Jira, outside the SE tool chain.
- What I did
- Linked requirements to the software verification reports, in the SE tools and in Jira, giving a clear view of verification coverage and open gaps
- Defined the means of verification for each requirement and derived test cases from the MBSE functional and component scenarios
- Consolidated the stakeholder requirements and wrote the System Requirements Document, traced down to every lower-level requirement
- Wrote the Software Requirements Document, with attributes (software components, topics) that map directly onto the software team’s existing workflow
- Built the MBSE model and brought it into design reviews with external stakeholders
- Reworked the change-request process so every change is logged, turned into requirements and traced through to verification
- Published SE guidelines on Confluence and SharePoint and coached colleagues through them
- Outcome
Verification coverage became visible at a glance: for every requirement, the team and the customer could see how it was verified and what was still open. Reviews with customers could be closed on clear evidence, and the software team could confirm its work was complete. External stakeholders gave direct positive feedback, the SE team grew from 3 to 13 people, and management added Polarion to the tool chain.

Clear verification coverage turns a customer review from a discussion into a check.
