market-sizing

To calculate market size for TAM, SAM, and SOM, define market boundaries by geography and segment, then apply top-down, bottom-up, or value-based models to generate defensible estimates with transparent assumptions and sensitivity analysis.

Estimating a revenue pool requires defining the unit of demand and measurement basis, combining market benchmarks with customer counts, and testing pricing assumptions against uncertainty ranges to validate the opportunity size.

Yes, you can use bottom-up market sizing for spend pool analysis by aggregating individual segment adoption rates and pricing data to build auditable assumptions and measure specific demand across targeted geographies.

Conduct a sensitivity analysis for opportunity sizing by separating sourced facts from proxy assumptions, then testing variable inputs against structured data and public benchmarks to highlight validation priorities and uncertainty ranges.

Use top-down market sizing when applying broad industry benchmarks to a specific segment, and use bottom-up models when aggregating granular customer counts and adoption rates to validate unit-volume questions.

Yes, market sizing works for expansion upside by defining scope across new geographies and time horizons, applying structured data to estimate segment boundaries, and generating validation priorities for opportunity sizing.
