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.

Describe how you would design an A/B test and measurement plan to credibly attribute revenue uplift to a new predictive model. Include sample size considerations, metric definitions, pre-registration, and how resulting estimates would feed into the financial business case.

You're negotiating with a vendor that charges an upfront license plus per-transaction fees. How would you model break-even volume and calculate the indifference point where build (internal cost) becomes cheaper than buy? Explain assumptions and sensitivity you would test.

Write a short Python function to compute NPV given a list of yearly cash flows (first element is the initial investment at t=0, negative) and an annual discount rate. Show edge-case handling for zero-length input and all-negative cash flows.

Create a plan for post-implementation tracking to measure realized outcomes against your business-case forecasts. Specify data sources, instrumentation points, KPIs to track (both leading and lagging), reporting cadence, and governance to ensure data quality and accountability.

Given historical project estimates and actuals, how would you construct a model to produce confidence intervals around future benefit estimates (e.g., revenue uplift)? Describe statistical techniques (bootstrapping, Bayesian priors) you might use and how you'd communicate interval width to stakeholders.
