What a finished DDBA 4990 Week 5 segmentation brief looks like
Two pages, narrower than most first drafts expect. Here the firm is a garden center, and the segment is households that recently moved into newly built houses with bare lots, named in one line and defined in the next: buyers who closed on a new-construction home within two years and have not yet planted the yard. Wendell Smith's early account of segmentation, which treated one market as several smaller ones with different demand, is cited for the definition itself. The evidence section draws on county permit records to show the group exists in the trading area and on the firm's own receipts to show its baskets differ: larger, heavier on soil and shrubs, bought in spring bursts. A short paragraph states what the brief does not do, size or target the segment, since those decisions come later.
How a DDBA 4990 Week 5 example is structured
The brief moves from definition to evidence, and it treats the definition as the harder half. A name for the segment comes first, then the membership rule, written as conditions a reader could test against a single customer record. Demographic descriptors appear only where they sharpen that rule; age and income alone would sort people without predicting what they buy. Evidence then answers two separate questions in order: does the group exist in numbers worth noticing, shown from a public record, and does it behave differently, shown from purchase data. Each question gets its own paragraph, because evidence for existence proves nothing about difference. The closing paragraph marks the brief's boundary, leaving sizing and target choice to later work, and states the one test that would show the segment is not real.
A rule, not a label
New-construction buyers within two years, yard not yet planted. Each condition can be checked against a customer record, so the segment has edges. A label such as young families names a mood and sorts nobody reliably.
Evidence it exists
County building permits show how many new homes closed in the trading area over the period. The figure establishes presence, and the brief says clearly that presence alone is not yet an argument for anything.
Evidence it buys differently
Receipts tagged by delivery address show larger spring baskets weighted toward soil, shrubs and edging. This is the evidence the segment depends on, since a group that buys like everyone else is only a population.
What the brief leaves out
No sizing arithmetic, no target decision, no channel plan. The closing paragraph names those as later work and states the finding that would dissolve the segment: baskets indistinguishable from established homeowners in the same season.
Where marks go in DDBA 4990 Week 5
The membership rule carries the largest share, and it is tested by imagining a borderline customer: a rule that cannot sort a buyer who moved three years ago has not defined anything. Graders then look for two kinds of evidence and mark down briefs that offer only one, most often a public figure showing the group exists with nothing showing it buys differently. Wendell Smith earns credit when the brief uses his distinction to justify treating this group as its own market, not when he opens the paper as ornament. Precision of terms is checked throughout, so segment used where the brief means target, or market where it means customers, costs points in whichever section it appears. The falsification sentence at the close is rare, and graders notice it.

DDBA 4990 Week 5 questions, answered
How is a segmentation brief different from a marketing plan?
It is much narrower. A plan chooses targets, sets prices and allocates a budget, while this brief establishes only that one group exists and behaves differently. Holding that scope earns marks of its own. A brief that drifts into promotion ideas has spent its words on decisions the course has not yet asked for, and the definition usually suffers.
What counts as evidence that a segment buys differently?
Anything showing a pattern in purchase behavior: the firm's own sales records, a published industry survey broken out by customer type, or trade association data on spending. Evidence about attitudes is weaker unless tied to what people buy. The strongest briefs pair a public record showing the group exists with transaction data showing the difference.
Can a segment be defined by demographics alone?
It can be named that way, but it is rarely defined well that way. Demographics describe who people are, and segments are useful only when they predict what people will buy. Most strong briefs use a behavior or a situation, such as a recent move or a first purchase, and bring in demographics only to sharpen the membership rule.
