Performance Analyst — ArcKit Command Guide

Guide Origin: Official | ArcKit Version: [VERSION]

DDaT Role Family: Data Framework: UK Government DDaT Capability Framework

Overview

The Performance Analyst measures service performance and identifies improvement opportunities. You use ArcKit's quality and governance commands to assess architecture health, check conformance, and measure traceability — providing evidence-based insights for decision-making.

Primary Commands

Command	Purpose	Guide
/arckit:analyze	Run governance quality analysis — coverage, completeness, and gaps	Guide
/arckit:health	Scan for stale artifacts, orphaned requirements, version drift	Guide
/arckit:conformance	Check ADR implementation, architecture drift, and technical debt	Guide
/arckit:traceability	Measure requirements coverage — requirements to design to tests	Guide

Secondary Commands

Command	Your Involvement	Guide
/arckit:requirements	Understand the requirements being measured	Guide
/arckit:principles	Understand the principles being assessed against	Guide
/arckit:principles-compliance	Review principles compliance scores	Guide
/arckit:story	Contribute metrics and findings to the project narrative	Guide
/arckit:service-assessment	Provide performance data for service assessments	Guide

Typical Workflow

requirements → traceability → analyze → health → conformance

Step-by-step

1. Understand scope: Review /arckit:requirements for what should be measured
2. Check traceability: Run /arckit:traceability — are all requirements covered by design and tests?
3. Assess quality: Run /arckit:analyze for governance quality metrics
4. Scan for drift: Run /arckit:health to find stale, orphaned, or inconsistent artifacts
5. Check conformance: Run /arckit:conformance for ADR implementation and architecture drift

Key Metrics You Track

Metric	Source Command	What It Measures
Requirements coverage	/arckit:traceability	% of requirements traced to design and test
Governance quality	/arckit:analyze	Overall architecture governance score
Artifact health	/arckit:health	Stale artifacts, orphaned requirements, drift
Conformance score	/arckit:conformance	ADR implementation, consistency, debt
Principles compliance	/arckit:principles-compliance	Adherence to architecture principles
