その強み、本当に「強み」と呼べるのか
Is That Strength Really a Strength?
A small bakery is proud of one thing above all: its sourdough starter, kept alive and fed daily for eleven years. The owner calls it their biggest strength. A consultant visiting for an afternoon disagrees — or rather, complicates the claim.
A genuine strength, in business terms, has to clear four separate hurdles, not just one. First, does it actually create value the customer notices and cares about? Second, is it rare — do most competitors lack it? Third, is it hard to copy, even for a competitor who wants to badly? And fourth, is the business actually organized to make full use of it — turning that quality into bread people buy, rather than letting it sit unused in the back kitchen?
The eleven-year starter clears the first three hurdles easily: customers taste the difference, most nearby bakeries buy generic yeast instead, and eleven years of daily feeding cannot be copied overnight. But the fourth hurdle catches the bakery off guard — its menu barely mentions the starter, and most customers walk in without ever learning why the bread tastes the way it does.
A local tutoring service tells a similar story from a different angle. Its founder's rare skill at explaining calculus clearly is valuable, rare, and hard to copy — three hurdles cleared in an instant. But because the founder personally teaches every single session, the business cannot serve more students than one person's calendar allows, and a genuine strength never gets organized into something the business itself can scale.
A real advantage that nobody is told about is barely an advantage at all.

モデル要約と解説を見る
A bakery owner considers an eleven-year sourdough starter the business's biggest strength, but a real strength must clear four hurdles: value, rarity, difficulty to copy, and full use by the organization. The starter clears the first three easily, since customers notice the difference and competitors cannot copy eleven years of care overnight. But it fails the fourth: the menu barely mentions it, so customers never learn why the bread differs.

なぜこの要約になるか
- 元の英文は5段落＝「具体例①（パン屋の酵母種）→定義（強みの4条件）→評価（3つはクリア、1つは失敗）→具体例②（家庭教師サービス）→結論」という展開。70語では4条件を単語レベル（value, rarity, difficulty to copy, full use）まで圧縮し、2つ目の具体例は要約から外している。
- "letting it sit unused in the back kitchen"という比喩的な言い回しは要約では省略。同じ内容を"barely mentions it"という平易な表現に置き換えている。
- 「4条件のうち3つはクリア、1つは失敗」という評価の骨組みは、この英文でいちばん伝えたい構造なので、語数を削っても最後まで残している。

この英文が扱っているのは、既刊『戦略研、勝ち筋のつくりかた。』第6章の「VRIO」と同じ考え方です。価値・希少性・模倣困難性・組織的活用の4条件を満たす、本物の強みかを確かめる——このパン屋の例は、4つのうちどこで止まっているかを見極める練習になっています。
英語で自社・自校の強みを説明するときも、"strong point"と言うだけでなく、この4条件のどこが強いのかを具体的に言えると、説得力のある英文になります。
