• Related不成功ふせいこうWrittenWritten/formal word for an attempt that does not succeed; it says nothing about the quality of a finished work, unlike 「不出来」.
• Related失敗しっぱいNeutralThe everyday all-purpose word for something not working out; broader than 「不出来」, which is specifically about a poor result or finish.

• Related手違いてちがいNeutralA mix-up in arrangements or steps, as in 「こちらの手違いで」; procedure going wrong, not the finish of a work.

• RelatedしくじりCasualColloquial for botching something through one's own slip; more casual than 「失敗」, and not about the finish of a work.
• Related出来損ないできそこないCasualColloquial for a botched, defective thing itself; also an insult for a useless person — 「不出来」 only rates the result.
• RelatedやりそこないCasualColloquial for a slip-up while doing something; close to 「しくじり」, about the act going wrong rather than a shoddy product.
• Related不結果ふけっかWrittenRare written word for an outcome that falls short of expectations; close in sense to 「不出来」, but framed as a result, not a finish.

Use 「不出来」 for a poor result or finish — a work, performance, or harvest, as in 「今年の米は不出来だ」. For things not working out, the everyday word is 「失敗」; plain mistakes are 「間違い」. Written prose prefers 「不成功」「過ち」「過誤」「不結果」「失態」; casual speech 「しくじり」「出来損ない」「やり損ない」「粗相」「間違え」. 「手違い」 is a procedural mix-up, 「エラー」 a technical or baseball error, 「挫折」 a setback. The opposite is 「上出来」.
