## Product/Business Case: ValueInc food court (Costco-like)
ValueInc is a membership-based warehouse retailer. We also operate an **on-site food court** that is **open to both members and non-members**. The **hot dog combo** is the primary reason many people visit the food court.
Leadership is worried the food court may be attracting many **non-members who only buy hot dogs**, and that ValueInc is “missing profit” (e.g., subsidizing visits that don’t translate into profitable retail purchases or membership growth).
### Data (given as a summary table)
Assume you can obtain the following annual metrics (or a similar table). Define and use these fields explicitly in your analysis:
- **Member spending** (retail + food court), and **Non-member spending** (food court + any retail if allowed)
- **Profit margin for non-combo items** (food court items other than the hot dog combo)
- **Cost of combo** (unit variable cost of the hot dog combo)
- **Average spending for multi-purchase member** (members who buy food + also purchase other items)
- **Non-members annual revenue** (from food court and any allowed retail)
- **Hot-dog-only non-member visits** (# visits where a non-member purchases only the hot dog combo)
- **Multi-purchase member visits** (# visits where a member purchases hot dog combo + other items)
You may assume fixed costs exist (labor, rent allocation, equipment depreciation), but they are not provided unless you ask.

## Questions
Answer as a structured analysis. Clearly state assumptions and any additional data you would ask for.
1. **“How much profit did we not catch?”**
- Propose a rigorous way to quantify *missed profit* (or profit leakage) attributable to opening the food court to non-members and/or pricing the hot dog combo as a loss-leader.
- Specify what counterfactual you are comparing against.
2. **What are the main risks and drawbacks** of the current setup (food court open to non-members; hot dog combo as the main draw)? Include both business and measurement/causal risks.
3. **What can we do?**
- Propose multiple strategies to improve profitability while considering member experience (e.g., pricing, bundling, gating, conversion tactics, limits, promotions).
- For each strategy, identify a primary metric and at least 2 guardrails.
4. **Breakeven analysis:** What number of customers/visits do we need to breakeven?
- Define a breakeven equation that includes fixed and variable costs.
- The question has “hidden information”: clarify what segmentation you need (member vs non-member; hot-dog-only vs multi-purchase; incremental retail basket). Explain how the composition affects breakeven.
5. **Pricing change:** If the hot dog combo price increases to **$2.50** (from the current price), what should we do?
- Outline how you’d estimate price elasticity and forecast demand/profit impact.
- Discuss risks (e.g., brand perception, traffic drop, membership value proposition).
6. **Vertical integration:** Leadership is considering making hot dogs in-house.
- What factors should we consider (costs, capacity, quality, supply chain, regulatory, operational complexity)?
- Provide pros/cons and what analysis/experiment you would run before committing.
7. **Membership gating:** If we switch the food court to **members-only**, what are the advantages and disadvantages?
8. **Exit option:** What’s the cost to “get rid of” (shut down) the food court?
- List one-time and ongoing costs, and second-order effects on retention/traffic.
9. **Final risk check:** What risks should we be mindful of when interpreting results and making the decision (confounding, cannibalization, seasonality, selection bias, spillovers)?
Quick Answer: This question evaluates proficiency in revenue and profitability analysis, causal inference and experiment design, pricing and elasticity estimation, and customer segmentation within product analytics.
