本稿では,技術革新をきっかけとした既存品と代替品の代替構造を分析し,代替戦略の構築方法を提案する.まず,代替品と既存品の関係を4つに分類し,各分類毎に代替品企業の攻撃戦略と既存品企業の防衛戦略の定石を示す.次に,提案するフレームワークをICタグの事例に適用して,方法の有効性を例示する.代替品と既存品は,買い手のニーズをそれぞれの製品機能によって取り合う構造になっている.この機能に着目する考え方が本稿に一貫する着想である.

In order to investigate how cognitive skills develop in the course of expertise in Japanese fencing, regular (expert) and substitute (junior expert) players of a men's university varsity team were compared on performances on (I) a paper-pencil test of rules and concepts (Test a), (II) convergent problem solving tasks such as to predict a scorer's winning trick from a video just before it occurs (Test c-2), and (III) divergent problem solving tasks such as to judge players' skill from their postures (Test b-1), and to detect defects in them (Test b-2). Unexperienced college students also participated in the experiment in part. Both the experts and junior experts knew the rules and concepts of Japanese fencing well, and their performances were much better than the estimated baseline. Their performances in convergent problem solving were also equally well. In divergent problem solving, however, the experts were better than either the junior experts or the unexperienced. These results suggest that divergent problem solving skills need a longer time to develop.
