Questions to ask when given a market sizing task:
- What market specifically? (consumers or business or both? Does NY mean NYC or entire state?) 2. Ask if there is any data on any parameters I need (i.e. persons per household in target market) before estimating or any reason that parameters differe from national average, 3. Suggest research you would conduct to find parameters (may give data at this point) 4. Walk interviewer through thought process: A. Framework 2. Estimation/Research and get buy in on assumptions before doing any math, 3. Calculation, 4. So what?
