• Neglecting to tailor prompts to the client’s geography and channel structure.

FAQ

What is TAM vs SAM vs SOM in market sizing for management consultants?

TAM is the total addressable market, SAM is the serviceable available market, and SOM is the share of the market you can realistically capture. Use a mix of bottom-up and top-down prompts to estimate each.

How should I validate market size results from Gemini prompts?

Cross-check outputs with public data, pilot results, and known benchmarks. Include a data quality assessment and clearly document sources used.

Can I adapt these prompts for different regions or industries?

Yes. Replace placeholders with the specific region and industry, and adjust data sources and constraints to reflect local dynamics.

What outputs should I ask Gemini to produce for client-ready reports?

Ask for TAM, SAM, SOM, growth projections, drivers, data sources, assumptions, and a concise methodology summary.

How do I handle data gaps in market sizing?

Flag gaps clearly, propose data acquisitions, and provide TAM estimates with confidence ranges to reflect uncertainty.

How often should market sizing prompts be updated?

Update prompts whenever new data becomes available or market assumptions change significantly, ideally quarterly for active markets.
