About Market Sizing (PM Skills)

From Pawel Huryn's pm-skills collection.

Give it a product and market boundaries and it works out total, serviceable, and obtainable market size two ways, from the top down and from the bottom up. It can use reports or data you supply, or search the web for current figures, and it ends with growth projections plus a list of assumptions worth validating.

Good prep for an investor deck or a go/no-go call on a new market.
