grcengclub GRC evidence flow diagram
Use this skill to structure the GRC content and visual pattern for evidence collection, evidence lifecycle, audit evidence pipelines, and systems of record. Then use the drawio skill to generate the native editable .drawio file and optional PNG/SVG/PDF export.
Common Requests
- AWS Config to evidence repository to auditor review
- GitHub branch protection evidence
- quarterly access review lifecycle
Recommended Elements
Include these when relevant:
- evidence sources
- collectors
- repositories
- reviewers
- approvers
- auditors
- retention
- freshness
- cadence
Recommended Output Pattern
Produce a Swimlane evidence lifecycle or evidence data-flow diagram. Choose a layout that matches the audience:
- Executive: compact lifecycle/capability view with business impact labels.
- Auditor/assessor: explicit evidence, owner, control, cadence, and scope labels.
- Practitioner/engineering: operational systems, data paths, automation, failure/exception paths, and implementation detail.
draw.io Instructions
- Load and follow the
drawioskill. - Generate native mxGraphModel XML directly. Do not generate Mermaid as the final artifact.
- Use descriptive lowercase hyphenated filenames.
- Include a legend when colors, edge styles, or containers have compliance meaning.
- Validate XML well-formedness before finalizing.
- If PNG/SVG/PDF is requested, export with embedded diagram XML when the draw.io CLI is available.
Visual Conventions
- Blue: systems, platforms, services, and automated collectors.
- Green: implemented controls, approvals, validated evidence, and compliant outcomes.
- Orange/red: risks, findings, exceptions, overdue items, gaps, and failed controls.
- Gray: manual tasks, external parties, optional steps, and out-of-scope areas.
- Dashed containers: audit scope, trust boundaries, authorization boundary, or responsibility boundary.
- Solid edges: primary process or system flow.
- Dashed edges: evidence or attestation flow.
- Dotted edges: optional, manual, exception, or escalation flow.
Quality Bar
- Make ownership explicit.
- Label regulated data, control IDs, frameworks, and evidence repositories when known.
- Show decision criteria where the process branches.
- Avoid generic boxes like "Compliance" without a role, system, artifact, or action.
- Prefer editable source of truth over screenshots.
