MKTG 203 Chap.3 Buyer Behaviour and Decision Processes
Buyer Behaviour and Decision Processes
Buyer behaviour connects perceived consequences to search and choice. This chapter follows the five-stage decision process, separates financial, psychosocial, physical and performance risk, and preserves the assessed causal direction: perceived risk influences involvement, which helps determine whether problem solving is extended, limited or routine.

Key terms
- Problem recognition
- Perceiving a meaningful gap between an actual and preferred state.
- Perceived risk
- The expected seriousness and likelihood of an unfavourable consequence.
- Involvement
- The personal significance or relevance of a purchase decision.
- Limited problem solving
- A choice process using fewer sources, alternatives or criteria than extended problem solving.
Buyer Behaviour and Decision Processes FAQ
Does a high price always mean high financial risk?
No. Risk depends on the consequence for the buyer, including affordability, reversibility, responsibility and replacement cost. A high price can feel low risk to someone who can reverse the decision easily, while a smaller amount can matter greatly to another buyer. Use the scenario rather than the category alone.
Can involvement stay high when problem solving becomes limited?
Yes. Urgency can restrict the time available for search even when the decision remains personally important. Explain that involvement describes significance, while the problem-solving variation describes the method used. The buyer may compare fewer alternatives and rely on trusted recommendations without becoming indifferent to the outcome.
What causal direction should I write?
Perceived risk influences involvement, and involvement affects search and evaluation effort. The course's practice guidance specifically warns against reversing that arrow. Write the consequence first, explain why it makes the choice significant, then state how the buyer's search, criteria or alternative set is likely to change.
Can urgency reduce search without reducing involvement?
Yes. A consequential decision can remain personally important while a short deadline compresses information search and comparison. Explain both effects separately: the consequences support involvement, while limited time restricts process length. Calling the decision routine would require stronger evidence of familiarity and automatic choice.

Write four risk headings and diagnose one original purchase under each. Avoid using the same reason twice: money lost belongs under financial risk, embarrassment under psychosocial risk, harm under physical risk and failure to perform under performance risk. Then add the involvement conclusion and likely search behaviour.
Rework the case with less time available so you can separate high involvement from limited problem solving. Draw the five decision stages in order, but practise explaining when search or evaluation is compressed. For every answer, use scenario facts, not a product stereotype.
Finish by turning the diagnosis into marketing action: evidence, guarantees, transparent terms or recovery should reduce the specific risk you identified. Build a scenario matrix by varying one condition at a time. Keep the product constant and change who pays, whether return is possible, how urgent the choice is, whether the buyer has prior experience and what happens if performance fails.
Predict which risk changes, whether involvement changes and which stage becomes longer or shorter. This isolates causality and stops you from memorising product categories as automatically high or low involvement. For each risk, force yourself to write consequence, seriousness and likelihood in separate phrases.
A high price is evidence only when the loss matters to the buyer; another person paying may reduce direct loss without removing responsibility or regret. After the diagnosis, list the internal sources already available to the buyer and the external sources they may seek. Explain how urgency, familiarity and credibility affect the search set.
Practise distinguishing routine, limited and extended problem solving with two boundary sentences: why the chosen variation fits and why its nearest alternative fits less well. Add a post-purchase section to every longer answer. State the expectation used before purchase, the experience that would confirm or disconfirm it, and the response available to the organisation.
Finally, translate the risk into action without overpromising. Demonstration may reduce performance uncertainty, clear terms may reduce financial uncertainty and safety evidence may address physical concern. Match the evidence to the diagnosed consequence, then name what remains uncertain. This produces a full reasoning chain from scenario fact to behaviour and marketing response.
