What is a necessary component when analyzing alternatives in a Business Case?

When analyzing alternatives in a Business Case, a necessary component is Costs and benefits. This aspect is crucial as it provides a quantitative and qualitative assessment of the proposed options, allowing decision-makers to understand the financial implications and potential returns associated with each alternative.

By weighing the costs against the anticipated benefits, stakeholders can make informed decisions that align with the organization's objectives and resources. This analysis helps prioritize options that offer the best overall value and feasibility, ensuring that investments are directed towards initiatives that will yield the most significant positive impact.

In contrast, personal opinions, market trends, and architectural aesthetics may provide useful contextual information but do not constitute core components of a Business Case analysis. Personal opinions can be subjective and vary widely, while market trends offer insights that may not be directly tied to the cost-benefit analysis required for rigorous decision-making. Architectural aesthetics, though important in design discussions, do not directly influence the economic viability of business alternatives and thus are less relevant in this context.
