During the planning phase of an engagement to review an organization's research and development (R&D) expenditures, the Chief Audit Executive (CAE) is determining the appropriate resource allocation. Which of the following is the PRIMARY consideration for the CAE?

Worked Practitioner Scenario

Worked Example: Planning a New System Audit

Scenario: An internal auditor at Innovate Inc. is planning an audit of a newly implemented automated expense reporting system. Senior management is concerned about potential non-compliance with the company's recently updated travel and expense (T&E) policy, which could lead to unauthorized spending.

  1. Step 1: Establish a SMART Objective The primary objective must address management's concern directly: *"To assess whether controls within the new automated expense system are designed effectively to ensure all expense submissions for Q1 comply with the T&E policy, version 4.0."
  2. Step 2: Define a Sufficient Scope The scope must be precise enough to test the objective: *"The audit will cover all expense reports submitted through the new system from January 1 to March 31. The review will focus on system-enforced controls, including approval workflows, per diem limits, and receipt attachment requirements. Manual expense reports are excluded."
  3. Step 3: Establish Authoritative Criteria The criteria are the standards for evaluation: 1. Innovate Inc.'s 'Travel & Expense Policy,' version 4.0. 2. System design documents specifying the intended control mechanisms. 3. COSO Internal Control-Integrated Framework principles related to control activities.
  4. Decision and Misconception Correction Therefore, by following these steps, the auditor establishes a clear and defensible engagement plan that directly addresses the identified risk.
A tempting-but-wrong approach is to define the objective too broadly, such as "To review the new expense reporting system." This is a task, not an objective. If you picked an objective like this, you would fail to address the specific risk (non-compliance with the new policy) that triggered the audit. This leads to an unfocused engagement that may not provide the assurance management needs.

  • 1Use this four-step framework to deconstruct and answer questions about engagement planning components.
  • 2Step 1: Identify the Element. Read the question carefully. Is it asking for an objective (the 'why'), scope (the 'what, where, when'), or criteria (the 'what should be')?
  • 3Step 2: Analyze the Scenario's Core Risk. The best objective, scope, and criteria directly address the primary risk or goal mentioned in the prompt (e.g., fraud, non-compliance, inefficiency).
  • 4Step 3: Apply the Definitions. Match the options to their core definitions. An objective is an achievement statement. Scope is a boundary statement. Criteria is a standard or rule. An audit procedure is an action.
  • 5To remember the core components of engagement planning, use the OSCAR memory aid:
