The most important thing for an IS auditor to look for in a project feasibility study is an assessment of whether the expected benefits can be achieved. A project feasibility study is a preliminary analysis that evaluates the viability and suitability of a proposed project based on various criteria, such as technical, economic, legal, operational, and social factors. The expected benefits are the positive outcomes and value that the project aims to deliver to the organization and its stakeholders. The IS auditor should verify whether the project feasibility study has clearly defined and quantified the expected benefits, and whether it has assessed the likelihood and feasibility of achieving them within the project scope, budget, schedule, and quality parameters. The other options are also important for an IS auditor to look for in a project feasibility study, but not as important as an assessment of whether the expected benefits can be achieved, because they either focus on specific aspects of the project rather than the overall value proposition, or they assume that the project will be implemented rather than evaluating its viability.

In reviewing the IT strategic plan, the IS auditor should consider whether it identifies the major IT initiatives that are aligned with the organization's vision, mission, and objectives, and that support the business strategy and priorities12. The major IT initiatives should also be realistic, measurable, and achievable, and should have clear timelines, budgets, and responsibilities34.

The best test to provide assurance that a health care organization is handling patient data appropriately is compliance with local laws and regulations, as these are the primary sources of authority and obligation for data protection and privacy. Compliance with action plans, industry standards, or organizational policies and procedures are also important, but they may not cover all the legal requirements or reflect the current best practices for handling patient data.

The best metric to measure the alignment of IT and business strategy is the percentage of enterprise risk assessments that include IT-related risk. This metric indicates how well the organization identifies and manages the IT risks that could affect its strategic objectives and performance. A high percentage of enterprise risk assessments that include IT-related risk shows that the organization considers IT as an integral part of its business strategy and aligns its IT resources and capabilities with its business needs and goals
