The Serviceable Obtainable Market (SOM), or just Target Market, refers to the portion of the market that a company can realistically capture, given its resources, capabilities, and competitive positioning. It represents the actual subset of customers within the [[Serviceable Available Market (SAM)]] that the company can effectively reach and serve. SOM is crucial for businesses to estimate potential revenue and strategize market entry or expansion. In contrast, [[Total Addressable Market (TAM)]] encompasses the entire market demand for a product or service without considering any constraints; SAM narrows this down to the segment of the TAM that is within a company's reach based on its business model and geographical presence; while SOM further refines this to what is realistically attainable by factoring in competition and operational limitations.
