The Eight Dimensions

V — Velocity

How fast and reliably does the team ship? Deployment frequency, lead time for changes, CI/CD maturity, and feature flag usage.

I — Intelligence

How well is AI integrated? Prompt injection prevention, output validation, model version pinning, and fallback strategies.

B — Build Quality

How healthy is the codebase? Test coverage, type safety, dependency hygiene, and technical debt ratio.

E — Experience

How good is the user experience? Core Web Vitals, WCAG accessibility, responsive design, and error recovery patterns.

Security

How hardened is the attack surface? CSP headers, input validation, authentication patterns, and dependency vulnerabilities.

Scalability

How ready is it for growth? Horizontal scaling, database optimization, CDN strategy, and cache architecture.

Reliability

How resilient is it? Error budgets, monitoring coverage, alerting, disaster recovery, and graceful degradation.

Maintainability

How sustainable is it long-term? Documentation coverage, onboarding time, modular architecture, and upgrade path clarity.

Scoring Methodology

Each dimension is scored 0–100 using a combination of automated analysis and structured expert review. Dimensions are weighted by importance, with Security and Intelligence carrying higher weights due to the novel risks introduced by AI-generated code.
