GRC shared responsibility diagram

Use this skill to structure the GRC content and visual pattern for cloud/SaaS shared responsibility, inherited controls, provider controls, customer controls, and evidence ownership. Then use the drawio skill to generate the native editable .drawio file and optional PNG/SVG/PDF export.

Common Requests

• AWS/FedRAMP split
• SaaS provider/customer control split
• inherited cloud controls

Recommended Elements

Include these when relevant:

• provider
• customer
• shared
• inherited
• excluded zones
• control ownership
• evidence ownership

Recommended Output Pattern

Produce a Split responsibility, layered stack, or inherited evidence map. 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

1. Load and follow the drawio skill.
2. Generate native mxGraphModel XML directly. Do not generate Mermaid as the final artifact.
3. Use descriptive lowercase hyphenated filenames.
4. Include a legend when colors, edge styles, or containers have compliance meaning.
5. Validate XML well-formedness before finalizing.
6. 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.
