A segment you cannot reach separately is not a segment
If the same message reaches two groups through the same channel at the same cost, dividing them changes nothing operationally.
Market Core · Object
Target Audience
Who the organisation is actually trying to reach: how they divide, what they are worth, and where they can be found.
The term
What it is
Segmentation is only useful if the segments behave differently and can be reached separately. A division that produces neither is a demographic description, and most personas are demographic descriptions with a photograph attached.
This object answers who and where. What they are trying to get done is settled in the Business Core under the value proposition, and keeping the two apart stops the audience work turning into a second, weaker version of the jobs analysis.
The most consequential output is the value per segment, because it determines where effort goes and is almost never calculated.
Why it earns a place
What goes wrong without it
Personas invented internally describe the organisation
A profile assembled in a workshop reflects who the team imagines. One assembled from interviews and records reflects who actually buys.
Segments differ in value by more than anyone expects
Acquisition cost, retention and spend all vary by segment, and the ranking by revenue is frequently the reverse of the ranking by contribution.
One level in
The modules within target audience
Four working areas. The first divides the audience, the second describes it honestly, the third values it, and the fourth establishes whether any of it can be reached.
Segmentation
How the audience divides in ways that predict behaviour and permit separate treatment. The test is whether two segments would be served or reached differently.
LearnThe profile
What each segment is actually like, assembled from evidence rather than from a workshop. Descriptive enough to be recognised, honest enough to be wrong in public.
LearnSegment value
What each segment is worth: what they spend, what they cost to acquire, and how long they stay. The number that decides where effort goes.
LearnWhere they are
Where each segment can actually be reached, in what state of attention, and at what cost. The half of audience work that makes the rest usable.

Across the framework
What it touches
- Business CoreWhat the audience is trying to get done is analysed in the value proposition; this object settles who and where.
- Brand CorePositioning is aimed at a segment, and a position for everyone is aimed at nobody.
- Marketing ChannelsWhere the audience is determines which channels are even available.
- Data CoreSegment value requires the acquisition and retention data to be held at segment level.
Beyond the framework
Models worth knowing here
The Omnigoal says where this belongs and what it touches. It does not tell you how to think about it — other people have done that, and done it well. These are theirs.
Segmentation, targeting, positioning
Philip Kotler, building on Wendell R. Smith · 1956Divide the market, choose deliberately which parts to serve, then decide what you will mean to them.
The sequence is the argument. Segmentation without targeting produces a description of everybody; targeting without segmentation is a guess; and positioning decided before either is a slogan looking for an audience. Its enduring value is that it forces an explicit act of exclusion in the middle step.
- Reach for it when
- Whenever the answer to who the customer is comes back as anyone who needs it.
- Where it stops
- It assumes segments are stable and reachable as groups. Where behaviour varies more within a segment than between segments, the whole structure describes nothing.
Wendell R. Smith, “Product Differentiation and Market Segmentation”, Journal of Marketing, 1956; developed by Philip Kotler, Marketing Management, from 1967.
Personas
Alan Cooper · 1998A small number of specific, named, fictional people standing in for real patterns of behaviour.
Introduced in software design to stop teams building for an elastic user who conveniently wants whatever is easiest to build. The mechanism is specificity: a named person with a particular situation and a particular constraint cannot be quietly redefined mid-argument, and that is the entire benefit.
- Reach for it when
- When design or marketing decisions are being settled by whoever imagines the user most confidently.
- Where it stops
- Invented rather than researched, a persona is only a projection of the team, and demographic detail added for colour invites reasoning from stereotype.
Alan Cooper, The Inmates Are Running the Asylum, Sams, 1998.

Every model in the framework, and where each one belongsIf two segments would be served and reached identically, they are one segment with two names.
