Reports and metrics

Reports & Metrics for Integration Bring-up Debug focuses on integration issue mean-time-to-root-cause. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.

The job of a report is to convert integration issue mean-time-to-root-cause into a closure decision. One summary number is never enough without baseline, owner, and boundary context.

Debug the high-severity tail first; averages hide escape risk.

• Track integration issue mean-time-to-root-cause by domain and owner boundary.

• Store baseline manifest beside every metric snapshot.

• Report both immediate fix result and full regression result.

• Explicitly call out residual risk and ownership.

Reports and artifacts

• handoff completeness score

• manifest diff report

• model mismatch log

• bring-up issue tracker

Mini case study

Most top-level debug time was spent on collateral drift, not RTL defects.

Debug branches

• Validate handoff checklist

• Lock manifest hashes

• Correlate issue to owner boundary

Senior review question

Ask: what baseline, owner, and artifact prove this topic is truly closed?

Key takeaways

• State baseline manifest and owner with every closure metric.

• Run cross-domain regression after every top-level fix.

Common pitfalls

• Comparing results across different manifests.

• Unowned issues slipping through review cycles.

• Waiving risks without expiry and validation plan.
