Audit Control Designer

Generate audit-ready internal control design documents from As-Is business process inventories. Produces control IDs, assertion mappings, procedures, SoD analysis, KPIs, materiality thresholds, and implementation roadmaps. Use when building internal controls for new audit engagements, SOX/J-SOX compliance, or process improvement initiatives.

1. Overview

This skill transforms As-Is business process inventories into comprehensive internal control design documents. It leverages generalized patterns from real audit engagements across industries (F&B, retail, manufacturing) to produce draft control designs that cover all five audit assertions, segregation of duties, KPIs, and implementation roadmaps.

2. Prerequisites

None. This is a knowledge-based skill that uses reference documents for pattern matching and generation.

3. Quick Start

Step 1: Confirm Context Variables

Ask the user to confirm or specify:

  • Applicable accounting standard
  • Industry and company scale
  • Current system environment
  • Regulatory requirements

4. How It Works

Step 1: Confirm Context Variables

Ask the user to confirm or specify:

  • Applicable accounting standard
  • Industry and company scale
  • Current system environment
  • Regulatory requirements

If not specified, use defaults from the table above.

Step 2: Read As-Is Process Inventory

Read the user-provided process inventory. Identify:

  • Total number of processes
  • Business domains covered
  • Frequency distribution (daily/weekly/monthly)
  • Manual risk indicators

Step 3: Classify Processes into Business Patterns

Load references/process_patterns.md and classify each process into one or more patterns:

| Pattern | Domain | Key Processes | |—|—|—|

See the skill’s SKILL.md for the full end-to-end workflow.

5. Usage Examples

  • Starting internal control design from an As-Is process inventory
  • Building controls for a new audit engagement (SOX, J-SOX, PCAOB)
  • Designing controls for a specific business domain (AP, Inventory, COGS, Returns)
  • Reviewing and strengthening existing control frameworks
  • Preparing for initial audit readiness assessment

6. Understanding the Output

The output follows the template in assets/control_design_template.md. Key sections:

  • Control IDs follow the pattern: C-[DOMAIN]-[NN] (e.g., C-AP-01, C-INV-01)
  • Each control specifies: Type (Preventive/Detective), Assertion coverage, Procedure steps
  • SoD pairs are rated High/Medium/Low risk
  • KPIs include calculation formula and data source
  • Roadmap uses M+N notation (months from project start)
  • Open Questions are explicitly managed with options and recommendations

7. Tips & Best Practices

  • Begin with the smallest realistic sample input so you can validate the workflow before scaling up.
  • Keep skills/audit-control-designer/SKILL.md open while working; it remains the authoritative source for the full procedure.
  • Review the most relevant reference files first instead of scanning every guide: control_templates.md, materiality_framework.md, assertion_mapping.md.
  • Preserve intermediate outputs so you can explain assumptions, diffs, and follow-up actions clearly.

8. Combining with Other Skills

  • Combine this skill with adjacent skills in the same category when the work spans planning, implementation, and review.
  • Browse the broader category for neighboring workflows: category index.
  • Use the English skill catalog when you need to chain this workflow into a larger end-to-end process.

9. Troubleshooting

  • Re-check prerequisites first: missing runtime dependencies and unsupported file formats are the most common failures.
  • If a helper script is involved, run it with a minimal sample input before applying it to a full dataset or repository.
  • Compare your input shape against the reference files to confirm expected fields, sections, or metadata are present.
