Which analysis method is best for prioritizing new IT projects?

Investment portfolio analysis is the most suitable method for prioritizing new IT projects because it allows organizations to evaluate and compare various projects based on their expected returns, risks, and alignment with strategic objectives. This analytical approach considers a range of factors such as potential benefits, resource allocations, and overall impact on the organization's goals. By viewing IT projects as part of a broader portfolio, organizations can make informed decisions about where to invest their resources for maximum strategic benefit.

Other methodologies, while valuable in their respective contexts, do not specifically focus on the prioritization of IT projects in the same comprehensive manner. For example, internal control self-assessment emphasizes evaluating the effectiveness of existing controls rather than assessing new project initiatives. Information systems audit tends to focus on ensuring compliance and assessing the integrity of systems already in place, rather than prioritizing new investments. Business risk assessments identify potential threats impacting the organization but do not inherently provide a framework for deciding which IT projects should be pursued first. Therefore, investment portfolio analysis stands out as the most effective tool for this specific purpose.
