CIA engagement planning: from business risk to a work program

Engagement planning connects the business objective and risk to an audit objective, scope, criteria, resources and work program. Choose the evidence-gathering procedure after defining what the engagement must establish. In the current CIA Part 2 syllabus, planning carries 50%.

Risk to evidence
  1. 1

    Risk

    What could prevent the business objective?

    Output: Unauthorized supplier payments

  2. 2

    Objective

    What assurance is needed?

    Output: Supplier creation and payment approval operate

  3. 3

    Scope and criteria

    What is covered and what should happen?

    Output: Defined period, systems and approval policy

  4. 4

    Work program

    How will you obtain evidence?

    Output: Inspect and test the relevant records

A worked procurement planning grid

A useful plan makes the chain reviewable. Each procedure should support an objective, and each objective should respond to a risk. A large sample of irrelevant transactions still does not answer the audit question.

Example engagement design
  • Business objective

    Decision
    Pay only legitimate suppliers for authorized purchases
    Reason
    Defines the outcome at risk
  • Risk

    Decision
    Unauthorized supplier setup permits improper payments
    Reason
    Specifies what can go wrong
  • Audit objective

    Decision
    Evaluate setup and payment-approval controls
    Reason
    Targets the controls addressing that risk
  • Scope

    Decision
    Selected entities, system and review period
    Reason
    Defines the boundary of the conclusion
  • Criteria

    Decision
    Approved authorization rules and access requirements
    Reason
    Provides a defensible benchmark
  • Procedure

    Decision
    Test setup permissions and approval evidence
    Reason
    Connects evidence to the objective

Start the case with facts and an assurance question

A distributor has opened a second purchasing office. Supplier setup is centralized, but emergency payment approval can be performed locally. Management is concerned about payments to unauthorized suppliers. The proposed review covers the last quarter at both offices. These facts suggest a chain from setup permissions to emergency approvals and payment release.

A useful objective is to evaluate whether the relevant controls prevent or detect unauthorized supplier payments within the defined scope. “Audit procurement” is too broad to guide the work. “Check that forms look consistent” is specific but does not address the stated risk. Write the intended conclusion before selecting a procedure.

Turn each risk into evidence you can obtain

For unauthorized supplier creation, consider setup access and approval records. For bypass through emergency payments, examine who can invoke the exception and what subsequent review occurs. Determine the relevant population, period and systems before selecting records. Testing only the ordinary workflow would leave the emergency route unanswered.

Document why each procedure exists. Inspection of approvals may address authorization, but it does not automatically show that the supplier exists or that every payment is recorded. A procedure can be competently performed and still be irrelevant to the intended conclusion. The planning grid should expose that mismatch before fieldwork.

Agree suitable criteria before evaluating exceptions

If a process says approvals must be “timely,” determine what timely means before scoring transactions. Consider the applicable policy, requirement or suitable benchmark and discuss it with the relevant parties. Choosing a convenient threshold after seeing results weakens the conclusion.

Make the benchmark precise enough to apply consistently

Suppose policy requires emergency approvals to be reviewed “promptly.” One reviewer treats the same day as acceptable and another allows a month. Before classifying exceptions, establish suitable criteria using the applicable requirements and discussion with the relevant parties. Do not select a convenient definition after seeing which threshold makes the results look better.

Record the criterion, its source and how it applies to the population. If a policy was revised during the quarter, determine which version applied to which transactions. A current rule should not silently become the benchmark for an earlier period when a different authorized requirement governed the activity.

Reject a weak procedure and replace it

A proposed step says, “Ask the manager whether emergency approvals work.” Inquiry may help explain the process, but an unsupported answer does not by itself establish how it operated. Combine understanding of the process with relevant records and testing aligned to the objective.

Another proposed step selects only transactions that already have approval documents attached. That population can exclude the very failures you are looking for. Start from a defensible complete population of relevant activity and explain how the selection supports the conclusion. Selection convenience is not the same as audit relevance.

Address scope and resource limits explicitly

If required records are withheld or the team lacks a necessary skill, document the effect on the objective and escalate through audit leadership. Silently omitting a system while reporting on the whole process overstates the work.

Planning problem and response
  • Missing source records

    Response
    Identify the resulting evidence limitation
  • Unclear scope

    Response
    Specify period, entities, systems and exclusions
  • Insufficient expertise

    Response
    Arrange qualified resources or revise the plan appropriately
  • Procedure unrelated to objective

    Response
    Replace it with a test of the named risk and control

Revise the plan when an important record is unavailable

During planning, the team learns that emergency-payment logs were overwritten for half the quarter. First determine what is missing and whether other reliable evidence can address the objective. A bank record may establish that a payment occurred, but not necessarily that the required approval happened before release.

Bring the limitation and alternatives to audit leadership. Revise procedures or scope through the appropriate process and document the effect on the intended conclusion. Reporting that the full-quarter control operated effectively while silently testing only the available half would overstate the evidence.

Match skills and time to the actual work

If identifying bypass permissions requires system expertise the team lacks, recognize the gap before relying on an incomplete configuration review. Consider suitable specialist support and its resource implications. Adding more generalist hours does not necessarily replace the missing capability.

A sound revision names what will be covered, what remains uncertain, who will perform the work and what evidence the reviewer should expect. It also explains the tradeoff to the relevant stakeholders. This keeps the plan reviewable when constraints force a change rather than treating a deadline as permission to weaken the conclusion.

Review the plan before fieldwork starts

Use these questions to test the complete chain. The example decisions are illustrative; the applicable criteria and procedures depend on the engagement.

Planning review gates
  • Objective

    Evidence of a coherent plan
    Names the assurance question and relevant risk
    Reason to revise
    Only names a department or a document
  • Scope

    Evidence of a coherent plan
    Identifies period, systems, locations and boundaries
    Reason to revise
    Conclusion would cover untested activity
  • Criteria

    Evidence of a coherent plan
    Provides an applicable and defensible benchmark
    Reason to revise
    Threshold chosen after results are known
  • Work program

    Evidence of a coherent plan
    Connects each step to the evidence needed
    Reason to revise
    Large amounts of irrelevant testing
  • Resources

    Evidence of a coherent plan
    Has the access, skills and capacity needed
    Reason to revise
    Missing capability is hidden by extra hours

A final self-check

Change the original risk from unauthorized suppliers to late payment of valid suppliers. The objective, criterion and evidence should change too. If your plan remains identical except for its title, it may be a generic checklist rather than a response to the risk.

That variation is a useful CIA learning exercise: keep the process, change the decision and rebuild the reasoning. The quality of the plan lies in its connected logic, not in how many rows it contains.

Original worked case

A test that answers the wrong question

The objective is to detect liabilities omitted at year-end. The auditor selects only transactions already recorded in accounts payable.

Reveal the decision and reasoning

Start from evidence of goods or services received and trace to payable or accrual records for the relevant period.

A population of recorded payables can support testing recorded items, but it excludes the omissions the objective is seeking.

An editorial teaching example, not an official IIA question or a prediction of exam content.

Common questions

Is an engagement plan the same as the annual audit plan?
No. The audit plan prioritizes engagements across the organization. Engagement planning defines objectives and work within one selected engagement.
Why does the objective come before the procedure?
You need to know what conclusion the evidence must support. A technically valid procedure can still be irrelevant to the stated risk.
