An IS auditor has identified deficiencies within the organization's software development life cycle (SDLC) policies. The SDLC is the process of planning, developing, testing, and deploying software applications1. SDLC policies are the guidelines and standards that govern the SDLC process and ensure its quality, security, and compliance2. Deficiencies in SDLC policies can lead to various risks, such as:
Software errors, bugs, or vulnerabilities that can affect the functionality, reliability, or security of the applications3 Software failures, delays, or overruns that can affect the delivery, performance, or customer satisfaction of the applications3 Software non-compliance that can result in legal, regulatory, or contractual violations or penalties3 The next step that the IS auditor should do after identifying deficiencies in SDLC policies is to communicate the observation to the auditee. The auditee is the person or entity that is subject to the audit and is responsible for the area being audited4. In this case, the auditee could be the software development manager, the project manager, or the senior management of the organization. Communicating the observation to the auditee is important for several reasons:
It allows the IS auditor to verify the accuracy and validity of the observation and gather additional evidence or information from the auditee4 It gives the auditee an opportunity to respond to the observation and provide their perspective, explanation, or justification for the deficiencies4 It enables the IS auditor to discuss with the auditee the potential impact, root cause, and remediation plan for the deficiencies4 It fosters a collaborative and constructive relationship between the IS auditor and the auditee and promotes transparency and accountability in the audit process4 The other options are not as appropriate as communicating the observation to the auditee. Documenting the findings in the audit report is a later stepthat should be done after communicating with the auditee and finalizing the observation. Identifying who approved the policies is not relevant for addressing the deficiencies and may imply blame or fault on a specific person or group. Escalating the situation to the lead auditor is not necessary unless there is a serious disagreement or conflict with the auditee that cannot be resolved by normal communication. Therefore, option D is the correct answer.

The most important thing for an IS auditor to review when evaluating the accuracy of a spreadsheet that contains several macros is the formulas within macros. Macros are sequences of commands or instructions that can automate tasks or calculations in a spreadsheet. Formulas are expressions that perform calculations on values or data in a spreadsheet. The accuracy of a spreadsheet depends largely on whether the formulas within macros are correct, consistent, and complete. The IS auditor should review the formulas within macros to verify that they produce the expected results and do not contain any errors or inconsistencies. The other options are not as important as formulas within macros, as they do not directly affect the accuracy of a spreadsheet. Encryption of the spreadsheet is a security control that can protect the confidentiality and integrity of the spreadsheet, but it does not ensure its accuracy. Version history is a document control feature that can track and manage changes to the spreadsheet, but it does not verify its accuracy. Reconciliation of key calculations is a validation technique that can compare and confirm the results of calculations with other sources, but it does not evaluate the accuracy of formulas within macros.

The primary purpose of documenting audit objectives when preparing for an engagement is to identify areas with relatively high probability of material problems. Audit objectives are statements that describe what the audit intends to accomplish or verify during the engagement. Audit objectives help the IS auditor to focus on the key areas of risk or concern, to design appropriate audit procedures and tests, and to evaluate audit evidence and results. By documenting audit objectives, the IS auditor can identify areas with relatively high probability of material problems that may affect the achievement of audit goals or business objectives.
Addressing the overall risk associated with the activity under review, ensuring maximum use of audit resources during the engagement and prioritizing and scheduling auditee meetings are also purposes of documenting audit objectives, but they are not as primary as identifying areas with high probability of material problems.
