The Best Approach to Prioritize Projects in an IT Portfolio

D.

In order to prioritize various projects in an organization's IT portfolio, the organization needs to evaluate each project's potential benefits and risks, as well as its alignment with the organization's strategic goals and objectives. This requires a systematic and structured approach to evaluating and comparing projects against each other.

Out of the given options, the BEST way to prioritize various projects in an organization's IT portfolio is through the use of business cases. A business case is a document that outlines the justification for a project, including its potential benefits, costs, risks, and alignment with the organization's strategic goals and objectives. A well-developed business case can help decision-makers evaluate the relative merits of different projects and make informed decisions about which projects to pursue.

Total cost of ownership (TCO) is a financial metric that takes into account the direct and indirect costs associated with owning and operating an IT system or project over its entire lifecycle. While TCO can be useful in assessing the financial impact of different projects, it may not provide a complete picture of each project's potential benefits and risks, or its alignment with the organization's strategic goals and objectives.

Industry trends can provide valuable insights into emerging technologies, market trends, and competitive dynamics that may impact an organization's IT portfolio. However, relying solely on industry trends to prioritize projects may not take into account the unique needs and objectives of the organization, or the specific context in which it operates.

Enterprise architecture (EA) is a strategic framework that helps organizations align their IT systems and projects with their overall business goals and objectives. While EA can be useful in guiding the development and prioritization of IT projects, it may not provide a comprehensive evaluation of each project's potential benefits and risks, or its alignment with the organization's strategic goals and objectives.

In summary, while all of the options provided may have some value in prioritizing IT projects, the BEST way to prioritize various projects in an organization's IT portfolio is through the use of business cases. Business cases provide a structured and systematic approach to evaluating each project's potential benefits and risks, as well as its alignment with the organization's strategic goals and objectives.
