When conducting a post-implementation review, an IS auditor must assess the business case that was used to justify the implementation of the project. The purpose of this assessment is to ensure that the business case was accurate and complete, and that the project has delivered the expected benefits.
Option A states that the feasibility of alternative project approaches has been assessed. This is an important consideration when conducting a post-implementation review, as it helps to determine whether the project was implemented using the most appropriate approach. The IS auditor should review the documentation related to the project to determine if alternative approaches were considered and evaluated.
Option B states that the business case has not been amended since project approval. This is also an important consideration, as any changes to the business case after project approval could impact the project's success. The IS auditor should review the documentation related to the project to determine if any changes were made to the business case and whether they were approved.
Option C states that quality assurance measures have been applied throughout the project. This is also an important consideration, as quality assurance helps to ensure that the project has been completed to a high standard. The IS auditor should review the documentation related to the project to determine if quality assurance measures were applied throughout the project.
Option D states that amendments to the business case have been approved. This is important to ensure that any changes to the business case have been properly reviewed and approved by the appropriate stakeholders. The IS auditor should review the documentation related to the project to determine if any changes were made to the business case and whether they were approved.
Therefore, based on the above, the most appropriate option for the IS auditor to ensure while assessing a business case as part of a post-implementation review would be Option D: Amendments to the business case have been approved.
