MARK1001 Chap.2 Customer Loyalty
Customer Loyalty
Loyalty can refer to attitude, purchase share or tenure, and those measures should not be substituted for one another. Repertoire markets normally contain divided purchasing across several brands, while subscription markets make provider exit easier to observe.
This chapter interprets purchase sequences, time windows and market structure before recommending a retention tactic, and it challenges the assumption that satisfaction is the only cause of continued use or defection. Behavioural evidence becomes meaningful only after the category and observation window are stated.
A light buyer can look solely loyal or lapsed in a short period without changing preference, while price, availability and switching friction can sustain or interrupt use. Strong diagnosis therefore reports the pattern first, considers market structure and rival mechanisms next, and recommends an action whose effect can be distinguished from ordinary buying variation.

Customer Loyalty FAQ
Can a buyer like a brand and still switch?
Yes. Favourable attitude and purchase behaviour are related but distinct. Availability, price, occasion and ordinary repertoire buying can move a purchase to another brand even when the focal brand is liked. Report the attitude evidence and behavioural sequence separately before explaining their relationship.
What makes subscription loyalty different?
Subscription categories usually involve one provider at a time, so complete category share can be structurally normal and cancellation becomes a visible exit. That pattern does not reveal why the customer stayed or left. Service access, price, contract terms and satisfaction require separate evidence.
Why can a short time window mislead?
A light buyer may make one purchase and appear solely loyal, or make no purchase and appear to have lapsed. A longer window creates more opportunities for repertoire buying and repeat purchase to appear. Always attach the observation period to any loyalty percentage or defection claim.
Exam move
Practise on purchase sequences. For each one, calculate focal-brand share, count the repertoire and state the observation window. Then add one attitude measure and one tenure fact to see why the constructs can disagree. Compare a grocery category with a subscription service so the market-structure boundary becomes automatic.
Build three short sequences for the same buyer: one observed over four weeks, one over six months and one over two years. Calculate brand share and repertoire size in each window, then explain how a light buyer can look solely loyal, lapsed or newly acquired merely because purchase opportunities are sparse. Never report a loyalty percentage without the category, population and observation period.
Create a construct table with behavioural loyalty, attitudinal loyalty, tenure and defection in separate rows. For each row, record an appropriate measure and one invalid inference. Repeat purchase does not by itself prove commitment; a high rating does not guarantee the next purchase; long tenure may reflect inertia; switching does not prove dissatisfaction.
Use the distinction to mark each sentence in a sample answer as observation, explanation or recommendation. Compare repertoire and subscription settings. In a repertoire market, buyers commonly divide purchases across acceptable brands, so a competitor appearing in the sequence is not automatically a defection.
In a subscription market, one provider at a time may be structurally normal, making cancellation more visible but still not revealing its cause. Add price, access, service failure and changing need as rival mechanisms. Practise a five-mark response with one point for the observed pattern, one for market structure, one for attitudinal evidence, one for a rival explanation and one for a testable action.
Recommendations should remain reversible: protect availability and reliability before investing in an emotional program whose incremental effect is unknown. End revision by designing a small measurement plan. Specify the purchase data, attitude item, comparison period and category norm needed to decide whether a buyer or brand is unusual.
Then state what result would favour convenience, preference or ordinary repertoire buying. This makes the conclusion proportional to the evidence rather than to the manager's preferred story.
