A comprehensive audit plan should address:

• Audit objectives and scope
• Risk assessment and control evaluation
• Audit procedures and testing methodology
• Resource requirements and timeline
• Stakeholder communication plan
• Budget and cost estimates

Audit objectives should be SMART:

Example Objectives:

• Assess the design and operating effectiveness of financial transaction controls
• Evaluate whether account reconciliations are performed timely and accurately
• Determine if system access controls are adequate and properly maintained

Risk-based auditing focuses on areas with the highest impact and likelihood of problems:

• Identify key business processes and systems
• Assess risk level (high, medium, low) for each area
• Consider historical issues, turnover, and complexity
• Prioritize audit scope based on risk level
• Document risk assessment results

Clearly define what will and will not be included in the audit:

• In Scope: Specific processes, systems, locations, and time periods
• Out of Scope: Areas explicitly excluded and why
• Constraints: Any limitations (access, time, resources)
• Related Parties: Departments, vendors, or third parties involved

Example scope statement:

Define what each control should accomplish:

• Authorization: Transactions are properly authorized
• Completeness: All transactions are recorded
• Accuracy: Transactions are recorded correctly
• Safeguarding: Assets are protected
• Segregation of Duties: Proper separation of incompatible functions
• Detection: Invalid transactions are identified and corrected

Create specific testing procedures for each control objective:

• Procedure Number: Unique identifier (e.g., FIN-001)
• Objective: What control is being tested?
• Nature: Type of test (inquiry, observation, testing, etc.)
• Sample Size: Number of items to test
• Expected Results: What should be found if control is effective
• Evidence Required: Documentation needed
• Responsible Auditor: Who will perform this procedure
• Timeline: When should this be completed

Ensure you have adequate resources:

• Staffing: How many auditors and what skill levels needed?
• Hours: Estimate total audit hours (planning, execution, reporting)
• Expertise: Do you need subject matter experts?
• Tools: What software or tools are required?
• Outsourcing: Will any work be outsourced?
• Budget: Total cost estimate

Develop a realistic schedule:

• Planning phase: ___ weeks
• Fieldwork/execution: ___ weeks
• Finding analysis: ___ weeks
• Report preparation: ___ weeks
• Management review: ___ weeks
• Board presentation: ___

Determine who needs to be involved:

• Audit Committee/Board: Who oversees the audit?
• Management: Department heads and process owners
• Internal Users: People providing information
• External Parties: Vendors, customers, regulators

Plan communication throughout the audit lifecycle.

Plan what documentation you'll need to gather:

• Process documentation and flowcharts
• Policy and procedure manuals
• System documentation and user guides
• Transaction samples and testing data
• Control evidence and reconciliations
• Prior audit reports and management responses
