1. What is TAM (Total Addressable Market)?

Definition: TAM represents the total demand for a product or service within a specific market. It encompasses the entire revenue opportunity available if a product or service achieved 100% market share. TAM is a broad measure that indicates the maximum potential size of the market.

Importance:

Market Potential: TAM helps businesses understand the overall potential of a market. It provides a macro view of the market size and helps in assessing the feasibility of entering a new market or expanding within an existing one.

Investment Decisions: Investors use TAM to gauge the potential return on investment. A larger TAM can be an attractive factor for investors looking for high-growth opportunities.

Strategic Planning: Knowing the TAM assists companies in setting long-term goals and strategies. It informs decisions on product development, market positioning, and resource allocation.

Example: If a company is developing a new software solution for the healthcare industry, TAM would include the total revenue potential from all healthcare organisations worldwide that could potentially use this software.

2. What is SAM (Serviceable Available Market)?

Definition: SAM is a subset of TAM and refers to the portion of the total market that a company’s products or services can target, considering geographical, regulatory, or other limitations. It represents the segment of the market that is accessible with the company’s current capabilities and business model.

Importance:

Focused Strategy: SAM helps businesses refine their market strategy by identifying the specific segments that can be realistically targeted. It narrows down the market to those who can be effectively served.

Resource Allocation: By understanding SAM, companies can allocate resources more efficiently, focusing on the segments that offer the greatest opportunity for growth within their operational scope.

Sales Targets: SAM provides a more realistic picture of achievable sales targets. It helps in setting practical goals and measuring performance against the potential market.

Example: For the same healthcare software company, SAM might be the market for healthcare organisations in North America and Europe that are looking for new software solutions, excluding regions where the company cannot currently provide support.

3. What is SOM (Serviceable Obtainable Market)?

Definition: SOM is a further subset of SAM and represents the portion of the market that a company can realistically capture within a given timeframe. It reflects the market share that a company can achieve considering its resources, competition, and market dynamics.

Importance:

Realistic Projections: SOM provides a pragmatic view of what a company can expect to achieve in terms of market share. It factors in competition, market conditions, and internal constraints.

Operational Planning: Understanding SOM helps in setting actionable goals, designing marketing strategies, and planning sales efforts. It aids in forecasting revenue and measuring the effectiveness of market strategies.

Performance Measurement: SOM serves as a benchmark for evaluating performance. It helps businesses track progress and adjust strategies based on actual market capture versus projected targets.

Example: For the healthcare software company, SOM might be the estimated market share of healthcare organisations in North America and Europe that the company can realistically capture within the first two years, given its current resources and competition.
