Rank the purchase drivers that actually move your category

Purchase drivers are the reasons a consumer picks one product over the alternatives in front of them: price, availability, brand trust, pack, taste, recommendation, and routine. Purchase decision drivers rank against each other, so the useful output is an order, where a flat list hides which one led. The driver that leads in one market often sits third in the next.

It depends on the category and the market, which is the point of measuring it. Across consumer goods the key purchase drivers usually reduce to four: what it costs, whether it was there, whether the buyer trusts it, and whether they always buy it. Where a category is commoditised, the marginal driver decides share, and it is rarely the one the plan assumes.

Purchase drivers examples split into rational and situational. Rational: price per unit, pack size, ingredient or spec, warranty. Situational: the product was in the cooler by the till, the usual choice was out of stock, a friend recommended it, the display was at eye level. Situational drivers are the ones share data hides completely, because the numbers record the outcome and skip the aisle.

The emotional drivers of purchase are the ones a consumer feels before reasoning about: trust, familiarity, status, reassurance, and belonging. They rank alongside price, and often above it, especially in categories where the products sit close on spec. Sena captures them by asking about the choice that was made, in the consumer’s own words, before offering any prompt.

Share data reports the result. Driver analysis reports the cause, ranked, per segment. Both are needed, and they answer different questions: share tells you a change happened, and the driver model tells you which lever is connected to it. Acting on share alone means choosing a lever by assumption.

Yes, and the difference usually sits in the order more than in the list itself. Gen z purchase drivers tend to weight recommendation and values higher, while price still ranks near the top in most categories. The practical answer is to size each group and report it separately, since a segment that decides differently from the majority can still hold a quarter of the market.

Yes, and the gap is wide. Smartphone purchase drivers weight specification, price, and the plan attached to the handset, and the decision runs over weeks. A snack bought at a till runs in seconds, on availability and habit-level familiarity. A driver model is only useful when it is built for one category, in one market, at a time.

Sena asks consumers about a purchase they actually made, then orders the reasons by how much each one carried the decision, split by market, channel, and demographic. It sizes the group behind every driver, so you know what share of the market each one represents. Sena then reads what was available in the stores those consumers use, which tests whether a stated reason matches the choice they had.
