The future-tense framing tripped me up more than I expected.
Start by clarifying the scope and assumptions, then use a structured estimation approach (e.g., TAM/SAM/SOM or a demand-side model) to derive a plausible range. Anchor your estimate with analogies to similar product categories (e.g., smartwatches, VR headsets) and explicitly state key drivers and uncertainties.
Pro tip: Show that you understand the difference between a top-down and bottom-up estimate, and that you can triangulate using multiple methods. Also, acknowledge that the estimate is a range, not a single number, and that the drivers are more important than the exact figure.
Ask clarifying questions to define what 'AR-enabled glasses' means (e.g., standalone vs. tethered, consumer vs. enterprise) and the target market. Confirm whether the estimate is for all global shipments or a specific segment.
Select a method such as top-down (TAM based on smartphone or glasses users) or bottom-up (adoption curves by segment). Explain why you chose it and outline the key variables.
Break down the market into segments (e.g., early adopters, enterprise, consumers) and estimate adoption rates, replacement cycles, and pricing. Use analogies from similar technologies (e.g., smartwatches, VR) to inform assumptions.
Compute a base estimate and then adjust for factors like price, utility, and competition. Sanity-check by comparing to adjacent markets (e.g., total glasses market, smartphone shipments).
Conclude with a range (e.g., 10-50 million units) and highlight the top 3-5 factors that could swing the estimate up or down, such as killer apps, price points, and tech breakthroughs.
