Quality is more than functional correctness.
Most reviews stop at ‘does it work?'. Real quality emerges from the interplay of four dimensions. HQM Quality Coach looks at every requirement through all four — weighted by what actually matters.
Product (ISO 25010)
Functional correctness & the eight quality characteristics.
Process
How the work flows.
People
Skills & collaboration.
Values
Priorities & trade-offs.
What the skill does
Reviews requirements & user stories
Scans every story across the eight ISO 25010 characteristics and surfaces real quality gaps.
Challenges vague words
‘fast', ‘secure', ‘scalable', ‘robust' — rewritten into measurable, verifiable criteria.
Rates & improves NFRs
A–E rating across 10 dimensions, with a refinement template for every requirement.
Designs risk-based test strategies
Names the product risk first, picks fitting test techniques — and states clearly what each one misses.
Right-sizes itself
Estimates risk (Light / Standard / Deep) and scales depth: a trivial UI tweak gets a short answer, a payment flow gets the full treatment.
Five output modes
The skill delivers exactly the right format for the moment.
Executive Review
A dashboard-style card-and-badge board review. Includes the ‘Top 3 Blocking Questions'.
Detailed Review
The long-form report for deep analysis & workshop prep.
NFR Rating
Existing NFRs rated A–E and concretely improved.
Test Strategy
Risk-based test approach: which technique, why, and what it doesn't cover.
Backlog Mode
Jira-ready NFR stories, tasks and quality enablers.
Risk-based — from Light to Deep
Light
Cosmetic, internal tooling, low exposure, reversible → short review.
Standard
Customer-facing, data handling, moderate complexity → full Executive Review.
Deep
Auth, payments, multi-tenant, compliance → full review + explicit assumptions.
