Total market

Definition and boundary

Total market describes potential use with every constraint removed. The definition asks which organisations could use the product, not which organisations the current operation can serve. Read the total market glossary entry alongside this distinction.

Reachable market is narrower. It is the portion of the total market that the current operation can serve today, with its existing coverage, language and support. An organisation can therefore belong to the total market without belonging to the reachable market.

Where the distinction matters in practice

Use the distinction when discussing the scope of a market opportunity. If a discussion concerns organisations that could use the product without constraints, it concerns total market. If it concerns organisations the operation can serve now, it concerns reachable market.

For example, when existing language or support limits service, keep those limits explicit in the reachable-market assessment. Do not use the unconstrained universe as a description of current operational reach.

Neighbouring terms and CPM-E preparation

A segment groups people who behave similarly in the decision at hand. It is not simply another name for total market. In practice, the guide's segment sheet records defining behaviour and the most recent decision taken because of that segment.

Analogous offerings are comparable products used as an estimate base when there is no history of your own. They support estimation; total market defines the universe under consideration.

When preparing for the Certified Product Manager Enterprise certification, practise separating three questions: who could use the product without constraints, who can be served today, and which grouping reflects similar decision behaviour.
