A project business case is a document that describes the rationale and justification for initiating a project, based on its expected costs, benefits, risks, and feasibility. A project business case provides the most useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, because it helps the IS auditor to:
Understand the purpose, scope, objectives, and deliverables of the project
Assess the alignment of the project with the organization’s strategy, vision, and goals
Evaluate the value proposition and return on investment of the project
Identify the key stakeholders, sponsors, and owners of the project
Analyze the potential risks and issues associated with the project
Compare and prioritize the project with other competing projects
The other possible options are:
A. Project charter: A project charter is a document that formally authorizes and defines the high-level scope, roles, responsibilities, and authority of a project. A project charter provides some useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, but it is not the most useful information. A project charter does not provide enough details about the costs, benefits, risks, and feasibility of the project, which are essential for evaluating its suitability for an IT audit plan.
B. Project plan: A project plan is a document that outlines the detailed scope, schedule, budget, resources, quality, and communication plans of a project. A project plan provides some useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, but it is not the most useful information. A project plan does not provide enough information about the rationale, justification, value proposition, and alignment of the project with the organization’s strategy and goals, which are important for assessing its relevance for an IT audit plan.
C. Project issue log: A project issue log is a document that records and tracks the issues that arise during a project’s execution and how they are resolved. A project issue log provides some useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, but it is not the most useful information. A project issue log does not provide enough information about the purpose, objectives, benefits, and feasibility of the project, which are critical for determining its priority for an IT audit plan.
