What Is the Reality of Data Utilization in Market Development?

When developing markets for your products or services, it is essential to grasp the overall market size and set strategic goals. TAM, SAM, and SOM are cited as effective indicators for market analysis.

On the other hand, while many understand the importance of visualizing TAM, SAM, and SOM, there are likely many who are unsure of how to proceed specifically.

In this article, we will introduce methods for market analysis using TAM, SAM, and SOM, as well as how to actually calculate your company's TAM.

What Are TAM, SAM, and SOM?

The metric representing the overall revenue opportunity for a product or service is called the "Total Addressable Market (TAM)."
It is often defined as the maximum market size that can be captured and is considered a way to efficiently list potential customers.

The portion of the TAM that represents the target market is called the "Serviceable Available Market (SAM)."
The portion of the SAM that can be reached through a company's specific sales activities is called the "Serviceable Obtainable Market (SOM)."

Since the SOM can be interpreted as the target market share for a company's product or service, it is frequently used to calculate corporate sales targets.

Utilizing Corporate Data

Accurate corporate data is essential for understanding TAM, SAM, and SOM.

Calculating TAM

While calculating TAM efficiently is important, it is a prerequisite to possess the underlying corporate data.

Here, you can calculate your company's TAM by utilizing "LBC," a corporate database covering 12.5 million locations across Japan, uniquely built by uSonar.

First, let's calculate the TAM for your company or business.

Visualizing SAM/SOM

Furthermore, to perform the "filtering" necessary to create SAM and SOM, it is crucial to understand the corporate characteristics of both current and potential customers.

The ability to select companies based not only on industry or number of employees but also on axes such as "pain points" and "interests" significantly changes the precision of your filtering.

Additionally, the freshness of the information used for filtering is also critical.
