Key metric
1 governed workflow boundary for quality assurance review

Anchor QA in evidence and coaching

Quality assurance review breaks when cases, call transcripts, chat logs, rubric criteria, defect categories, customer impact, and coaching notes live in separate places. AI can help reviewers move faster, but the business value is more consistent scoring and earlier detection of customer-impact defects.

San Francisco Fed research on AI and small businesses underscores the need for usable implementation capacity. For QA, start with one queue, one rubric, and a manager who will review false positives before the workflow expands.

Use Copilot for reviewer assist, custom AI for QA governance

Copilot can summarize cases, extract call themes, and draft coaching notes when source material is available through Microsoft 365 permissions. That is useful for individual reviewer productivity, especially during calibration.

Custom AI becomes necessary when the company needs governed sampling, rubric scoring, evidence capture, supervisor queues, trend reporting, and integration with support or delivery systems. NIST should define monitoring and reviewer override controls; CISA guidance should inform how customer conversations and employee coaching records are protected.

Score consistency before automation volume

Deloitte's AI research is a reminder that adoption value has to survive production use. A QA pilot should compare human-only review, Copilot-assisted review, and a custom scoring workflow against the same case sample.

Measure review coverage, scoring consistency, false positives, supervisor override rate, coaching completion, rework reduction, and customer-impact defects caught earlier. Keep Copilot when reviewers need faster preparation. Build custom QA when the workflow needs repeatable sampling, scoring evidence, and manager queues.
