Final answer:
In business case analysis, alignment to the strategic plan and justification are two fundamental elements which ensure the case is in line with company goals and has a clear rationale.
Step-by-step explanation:
In a business case analysis, two elements that should always be included are: B: Alignment to the strategic plan, and C: Justification. Alignment ensures that the analysis is connected with the overall direction of the company and contributes to its long-term goals. Justification provides a reason for the proposal through a clear explanation, such as a cost/benefit analysis, market analysis, or outlining the science and rationale behind the choice.
It's essential to clearly document these elements to articulate the business case's value and rationale. These elements are vital in presenting a comprehensive analysis that can facilitate decision-making on the project.
