Business Case Development and Financial Analysis Questions

Skills and practices for building persuasive business cases and performing financial analysis to justify investments and prioritization. Topics include enumerating and estimating cost categories such as implementation, licensing, development, infrastructure, deployment and ongoing support; quantifying tangible benefits such as cost savings, revenue uplift, productivity improvements and efficiency gains; and accounting for intangible benefits such as risk reduction, flexibility and employee satisfaction. Financial techniques include total cost of ownership, simple return on investment, payback period, net present value using discounted cash flows, internal rate of return, lifecycle cost analysis and build versus buy comparisons. Candidates should be able to construct cash flow timelines, separate capital and operating expenses, perform sensitivity and scenario analysis, estimate ranges and confidence, model procurement and vendor tradeoffs, and state assumptions clearly. Practical communication skills include tailoring the financial narrative and level of detail for finance leaders, procurement partners, technical stakeholders and executive sponsors, showing break even and sensitivity charts, defining success metrics and timelines, and describing how to track and report realized outcomes after implementation.
