SR · 9 practicesSystem Definition and Realisation: From the acquirer's needs to a delivered, verified system.
System Definition and Realisation is where most of the evidence sits. Requirements, architecture, allocation, realisation, integration, verification, validation, configuration and delivery each leave a different artefact.
Can the team show how the system was defined, built, verified and delivered?

What good looks like
Every practice in this theme has a named owner, a dated artefact and a recorded answer to its questions.
What goes wrong
The theme fails when the artefacts exist but nobody can produce them on request, or when the practice is claimed from memory with no record.

Work the process, not the document
Open one practice, answer its three questions, and attach the evidence it names. Then move to the next. The process is complete when every row has a named owner, a dated artefact and a recorded answer to the questions. That is a higher bar than a policy, and a lower bar than a certification.
The paid kit carries the same rows with the owner, due date and status columns already in place, and a dated plan that sequences the six groups across the 120 days to the planning date.

The 40-practice register, the 120-item evidence index, the dated plan and the board brief, as PDF, CSV and XLSX. Five labelled rows are free on the specimen page.
