This question's explanation and your answers so far.
A 社では前年度に実施したビジネス戦略の評価を進めている。表に示す条件の場合，総合評価の評点は何点か。
| 分類 | 戦略項目 | 目標 | 実績 | 評価方法・基準 | 評点の重み付け |
|---|---|---|---|---|---|
| 定量項目 | 売上高増加率 | 2.5% | 2.4% | 売上高増加率の実績が，2%以上ならば，110点，1%以上2%未満ならば，100点，0%を超え1%未満ならば，90点，上記以外は0点 | 0.5 |
| 定量項目 | 新製品開発件数 | 2件 | 1件 | 新製品開発件数の実績が，2件以上ならば，110点，1件ならば，100点，上記以外は0点 | 0.3 |
| 定性項目 | 顧客満足度 | 4 | 4 | 顧客満足度の実績が目標よりも1ランク以上向上すれば，100点，上記以外は0点 | 0.2 |
〔総合評価の方法〕 (1) 戦略項目ごとの評価方法・基準によって評点を求める。 (2) (1)の評点に重み付けしたものを合計して総合評価の評点を求める。
75 points is the value you get when the sales growth rate is mistakenly scored as 90 points (90 × 0.5 + 100 × 0.3 + 0 × 0.2 = 45 + 30 = 75). It comes from thinking “the target is 2.5% but the actual is 2.4%, so it fell short = it belongs to a lower band” and picking the row “90 points if over 0% but less than 1%”. The criteria classify by the actual value itself, not by the gap from the target, so 2.4% falls under “2% or more” and earns 110 points.
82 points is the value you get when the number of new product developments is mistakenly scored as 90 points (110 × 0.5 + 90 × 0.3 + 0 × 0.2 = 55 + 27 = 82). It comes from inventing a rule that is not written in the table, such as “it is 1 short of the target of 2, so deduct points and give 90”. The table criteria say “110 points if 2 or more, 100 points if 1, 0 points otherwise”, so an actual figure of 1 is simply 100 points.
正解 The correct answer is ウ (85 points). As stated in 〔Overall evaluation method〕, the overall score is obtained in two steps: (1) find the score of each strategy item from its evaluation method/criteria, and (2) add up those scores after weighting them. First, apply the table criteria to each item. The actual sales growth rate is 2.4%, which matches the criterion “110 points if 2% or more”, so it is 110 points (note that even though it falls short of the 2.5% target, the criteria judge only the absolute value of the actual figure). The actual number of new product developments is 1, which matches the criterion “100 points if 1”, so it is 100 points. For customer satisfaction the target is 4 and the actual is also 4, so it does not satisfy “100 points if it improves by 1 rank or more over the target” and falls under “0 points otherwise”, giving 0 points. Next, weight them and total: 110 × 0.5 = 55, 100 × 0.3 = 30, 0 × 0.2 = 0, so 55 + 30 + 0 = 85 points. Therefore ウ is correct.
105 points is the value you get when customer satisfaction is mistakenly scored as 100 points (110 × 0.5 + 100 × 0.3 + 100 × 0.2 = 55 + 30 + 20 = 105). It comes from seeing a target of 4 and an actual of 4 and thinking “the target was met, so it deserves full marks”. The criterion for customer satisfaction is “100 points if it improves by 1 rank or more over the target”, and the same level does not count as an improvement, so it falls under “0 points otherwise” and scores 0 points.
