Analytics plan for taking a physical good to market: demand, unit economics, inventory
Company: Amazon
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager preparing to launch a new physical product: something that has to be designed, manufactured, stocked and shipped, rather than released as software. What data analysis would you carry out to support the launch? Cover what you would analyze before committing to it, while getting ready, and once it is on sale, and name the decision each analysis feeds.
```hint Inventory changes everything
Unlike an app, money is spent on tooling and stock before the first unit sells, and both too much and too little inventory are expensive. Think about which analysis lowers that risk at each stage.

### Clarifying Questions
- Is the product a company-branded device, a private-label everyday item, or something an outside seller lists in the store?
- Is it entering a category that already has competitors and sales history to learn from, or creating a new category?
- Which decision should the analysis drive first: whether to launch at all, what price to set, or how many units to order for the first production run?
- Will it be sold only online, or through physical retail partners as well?
### What a Strong Answer Covers
- Analyses organized around concrete launch decisions (go or no-go, feature set and price, first production quantity, launch plan), not a list of techniques.
- Demand evidence from several sources, such as market sizing, search and review data, competitor sales and concept or pre-order tests, turned into a forecast with a range.
- Unit economics that account for landed cost, fulfillment, returns and break-even volume.
- Inventory and supply-chain analysis that weighs stockouts against overstock under manufacturing lead times.
- A post-launch plan tracking sell-through, conversion, ratings, return reasons, defects and cannibalization, with preset triggers for action.
### Follow-up Questions
- Pre-orders come in at three times your base forecast. Do you increase the production order, and what do you check first?
- How would you forecast demand for a product type that has never been sold before?
- First-month returns are double the rate you planned for. How do you find out why?
Overview: A product manager prompt about the analysis needed before and after launching a new physical product. It tests market sizing and demand forecasting, pricing and unit economics with returns and fulfillment, inventory sizing under manufacturing lead times, and a post-launch measurement plan tied to concrete decisions.
