An IT manager is creating a business case to justify the investment required to replace existing technology with new cloud services to support a digital transformation strategy. What should be described in the section on opportunity cost?

Opportunity cost is a fundamental economic principle used in business case analysis. It represents the value or benefit of the next-best alternative that is given up when making a choice. In this scenario, the business case is for investing in cloud services. The opportunity cost section must therefore describe the potential value the organization would have gained if it had invested the same resources (money, time, people) into a different project instead. This helps stakeholders understand the full trade-off of the decision.

A. This describes the direct investment or implementation costs of the chosen project, which is a separate component of the business case, not the opportunity cost.
B. This describes the ongoing operational expenditure (OpEx) for the chosen cloud services, a key financial metric but distinct from the value of a foregone alternative.
C. This describes the expected benefits or return on investment (ROI) for the proposed project, which is the justification for the investment, not the cost of a missed opportunity.

Section 3.2.3, The Business Case: This section explicitly lists the components of a business case. It defines opportunity costs as "the loss of potential gain from other alternatives when one alternative is chosen." It also separately lists "Costs" (covering options A and B) and "Benefits" (covering option C) as distinct elements.

Lecture Notes, Lecture 1: Introduction and Fundamentals of Microeconomics: The course materials define opportunity cost as "the value of the best alternative use of a resource." This academic definition confirms that opportunity cost is about the value of the foregone alternative, aligning directly with option D.
