What this lesson covers
How do people move from a problem to a purchase, and what happens in their heads at each step?
- Need recognition, search, evaluation, purchase and post-purchase
- Psychological, social and situational influences
- Involvement and risk: from the emergency call to the considered purchase
- Heuristics, social proof and decision shortcuts
- How search and social reshaped the information search stage
Why this matters now
Placeholder for the lesson's opening story: a vivid, real moment where a marketer or small-business owner meets this exact problem.
You can now
Diagnose where buyers stall in the decision process, and what would move them to the next step.
For your own business or employer: When sales slow down, find the stage where buyers drop out before you change anything.

Industry Case
Bajada Plumbing & Drain
Local home service · Demand capture

Module 1 of 8 in this case
Two decisions, one homeowner
Go back to 2:10 a.m. and watch the homeowner decide. Need recognition takes one second: water on the tile. Information search takes thirty: “emergency plumber near me,” three names on a map. Evaluation is fast and ruthless: who's open, who has stars, who answers. The purchase is the first live voice. The post-purchase stage starts when the truck pulls up.
Now meet the same homeowner six months later, wondering whether to replace a 14-year-old water heater before it fails. Same person, a different decision: high cost, low urgency, a week of reading reviews and three quotes.
Bajada lives on both. Carmen sorts last year's jobs: about 60% were emergencies decided in minutes, and 40% were planned jobs decided over days. They need different marketing. The emergency is won by being visible and answering. The planned job is won by trust built before the need. Until now, Bajada has done neither on purpose.

Module 1 of 8 in this case
The cart that stopped at the size chart
At 11 p.m. on a 104-degree night, a woman scrolling in bed sees an Ocotillo & Ash reel, taps, and drops the wide-leg pant into her cart. It doesn't feel like a decision process. It feels like an impulse.
Then she reaches the size chart. Medium or large? The page shows one model, standing still, on a white background. She closes the tab.
Look closer and every stage is there, and two of them are where Lena loses money. Evaluation stalls on fit, because nothing on the page answers “how will this fit me?” And post-purchase leaks: 22% of orders send something back, almost always for size. A return isn't the end of a sale. It's the decision process running backward.

Industry Case
Tepary Kitchen
Local restaurant · Local and offline
Case update 1.2
Module 1 of 8 in this case
“It's always full”
“Where should we eat tonight?” is a group decision that takes about twenty minutes and ends with whoever has the strongest opinion. Rosa listens to her regulars and hears the influences: a friend's photo of the cheese crisp (social), a hot night when nobody wants to cook (situational), the family habit of “Friday is Tepary” (psychological).
And she hears the shortcut that hurts her most. “We drove by on a Saturday, the wait was 40 minutes, so we went somewhere else.” One packed night taught a whole neighborhood that Tepary is always full, even on the Tuesdays when it's empty.

Key terms
- Cognitive dissonance: The doubt or discomfort a buyer feels after a purchase, especially an expensive one, when they wonder whether they made the right choice.
- Consideration set: The short list of brands or options a buyer seriously considers at the evaluation stage.
- Consumer decision process: The five stages most buyers move through: need recognition, information search, evaluation of alternatives, purchase and post-purchase behavior.
- Decision shortcut: Any quick rule a buyer uses to simplify a choice, such as buying a familiar brand, the middle-priced option or the first result.
- Evaluation of alternatives: The stage when a buyer compares options against the criteria that matter to them, such as price, quality, convenience or trust.
- Heuristic: A mental shortcut, or rule of thumb, that lets people decide quickly without weighing every detail, such as "pick the one with the most reviews."
- Information search: The stage when a buyer looks for options and information, from memory, friends, reviews, search engines, social media or AI assistants.
- Involvement: How much a purchase matters to the buyer personally. High-involvement purchases get research and thought; low-involvement purchases are made quickly.
- Need recognition: The first stage of the decision process, when a buyer notices a gap between where they are and where they want to be, triggered by something inside (hunger, a broken water heater) or outside (an ad, a friend's new jacket).
- Perceived risk: The buyer's sense of what could go wrong with a purchase: losing money, wasting time, looking foolish or being unsafe.
- Post-purchase behavior: What a buyer thinks, feels and does after buying: satisfaction or regret, reviews, repeat purchases, returns and recommendations.
- Psychological influences: Factors inside the buyer, such as motivation, perception, learning, beliefs and attitudes, that shape a decision.
- Situational influences: Factors in the moment of decision, such as time pressure, location, the device being used, mood or an emergency.
- Social influences: Factors from the people around a buyer, such as family, friends, reference groups, culture and online communities.
- Social proof: The tendency to follow what other people do, especially when unsure. Reviews, ratings, testimonials and "bestseller" labels are forms of social proof.
