問 21
Incorrectア
Analyzing consumption behavior from the three perspectives of era, age, and generation is cohort analysis. It captures the characteristics of each generation (a group of people born in the same period) separately from era effects and age effects, which is different from ABC analysis that groups items in descending order of value.
- イ
正解 ABC analysis is a priority-management technique based on the Pareto principle (a small number of top-ranked items account for most of the sales or inventory value): items are arranged in descending order of value and divided into three groups—A, B, and C—by cumulative composition ratio. The A group, which contributes the most to sales or inventory value, is managed intensively, while effort is minimized for the C group, and the two are treated differently. Choice イ, “classifying the company's products into three groups in descending order of sales and analyzing them,” describes exactly the procedure of ABC analysis itself, so it is correct.
Incorrectウ
Analyzing the marketing environment from the three perspectives of Customer, Competitor, and Company is 3C analysis. It is a framework for organizing the business environment and has nothing to do with ABC analysis, which classifies items into A, B, and C in descending order of value. The two merely happen to line up three leading letter Cs; they are entirely different things.
Incorrectエ
Analyzing customers from the three perspectives of most recent purchase date (Recency), purchase frequency (Frequency), and purchase amount (Monetary) is RFM analysis. It is a customer-analysis technique used for tasks such as identifying valuable customers, and it differs from ABC analysis—which classifies products into three groups by sales amount—in both purpose and procedure.
- ABC analysis = a technique that, based on the Pareto principle, arranges items in descending order of value (sales, monetary amount, etc.) and classifies them into three groups—A, B, and C—by cumulative composition ratio for priority management (used together with a Pareto chart).
- The key point is being able to distinguish it from other confusingly similar three-axis frameworks (cohort analysis = era, age, generation; 3C analysis = customer, competitor, company; RFM analysis = most recent purchase date, frequency, amount).
