Category Entry Points
also: CEPs
Definition
Category Entry Points are the specific cues — occasions, needs, moods, locations, social contexts — that trigger a consumer to think about a category. CEPs are the measurable unit of mental availability. A brand's CEP portfolio breadth is a stronger driver of share than the depth of association with any single CEP.
CEPs are operationalized via the W-questions: When, Where, Why, With whom, With what, How feeling. Measurement uses prompted association strength — 'when you feel X, which brands come to mind?' — to estimate a brand's linkage to each CEP. Portfolio-level metrics (weighted breadth, CEP entropy) capture the network property that single-CEP scores miss.

Jobs-to-Be-Done Segmentation Using NLP: Mining Customer Reviews to Discover Unmet Needs at Scale
Christensen said customers 'hire' products for jobs. Traditionally, discovering those jobs required expensive qualitative research. NLP applied to millions of customer reviews can surface the same jobs — plus ones that interviews miss because customers can't articulate them.
