1on1はマネージャーのためではなく、チームメンバーのための時間です。アジェンダの70%はチームメンバーが設定すべきです。

Constructive feedback using the situation-behavior-impact framework 4. Development goals for the next period with measurable milestones 5. A career growth recommendation (promotion ready / on track / needs focus) 6. Talking points for delivering this review in person

テスト済み Feb 15, 2026
プロのコツ
レビュー期間中にメモを取っておきましょう。年末に思い出せるのは最近の出来事だけです。四半期ごとにメモを取ると、より公正で包括的なレビューが書けます。

Help me navigate a conflict on my team. People involved: [roles, not names] The conflict: [what happened and the disagreement] How long it's been going on: [timeline] Impact on the team: [how it's affecting work] Previous attempts to resolve: [what you've tried] Your relationship with each person: [context] Provide: 1. An honest assessment of what's likely driving the conflict beneath the surface 2. A mediation plan: who to talk to first, in what order, and what to say 3. Scripts for each conversation (opening lines, key questions, closing) 4. Boundaries to set: what behavior is unacceptable regardless of the dispute 5. A follow-up plan to ensure the resolution sticks 6. Warning signs that the conflict needs HR involvement or escalation
最適な用途: CLAUDE
Claudeは最も共感的な対立解決アプローチを提供し、両者の立場を理解した上で建設的な解決策を提案します。
テスト済み Feb 15, 2026
プロのコツ
対立を個人の問題ではなく、プロセスの問題として捉えましょう。「誰が悪いか」ではなく「何が問題を引き起こしているか」に焦点を当てると、建設的な対話が生まれます。

A work sample or take-home assignment that tests real job skills 5. Red flags to watch for during interviews 6. A candidate comparison matrix template for final decisions
最適な用途: GEMINI
Geminiは最も客観的な採用スコアカードを設計し、バイアスを減らす評価基準が明確です。
テスト済み Feb 15, 2026
プロのコツ
面接前にスコアカードを作りましょう。面接後に基準を作ると、好印象の候補者に合わせて基準を調整する確証バイアスが働きます。
意図的にチームカルチャーを構築する
Help me build a stronger team culture. Team size: [number] Work arrangement: [remote / hybrid / in-office] Current culture: [describe honestly — good and bad] Values I want to reinforce: [3-5 values] Biggest culture problem: [what's not working] Budget for team activities: [monthly amount] Design: 1. A team charter: norms, communication expectations, and decision-making process 2. 5 rituals that reinforce desired culture (weekly, monthly, quarterly) 3. A recognition system that's authentic, not performative 4. An onboarding experience that transmits culture from day one 5. How to address culture violations without being heavy-handed 6. Culture metrics: 3 ways to measure whether culture is improving
最適な用途: GEMINI
Claudeは最も深いチームカルチャー構築のアドバイスを提供し、価値観の定義から日常の実践までを繋げます。
テスト済み Feb 15, 2026
プロのコツ
カルチャーは宣言するものではなく、日々の行動で作るものです。リーダーが率先して体現しなければ、どんな価値観も絵に描いた餅です。
効果的な委任の仕組みを構築する
Help me delegate more effectively. My role: [title and responsibilities] Team members: [list each with their role and experience level] Tasks I currently do myself: [list 8-10 tasks with weekly time spent] Why I struggle to delegate: [perfectionism / trust / speed / explaining takes too long] Team's current capacity: [overloaded / balanced / has bandwidth] Create: 1. A delegation matrix: which tasks to delegate, to whom, and why 2. For each delegated task: the level of delegation (inform / recommend / decide / act) 3. A handoff template: context, expectations, deadline, and check-in schedule 4. A 'letting go' framework for recovering perfectionists 5. How to handle it when delegated work comes back below your standard 6. A 30-day delegation plan to gradually offload 40% of your current tasks
最適な用途: CHATGPT
ChatGPTは最も実用的な委任フレームワークを作成し、何を委任し、誰に委任し、どうフォローアップするかが明確です。
テスト済み Feb 15, 2026
プロのコツ
「自分でやった方が早い」は短期的には正しくても、長期的にはチームの成長を妨げます。最初は遅くても、投資と考えて委任しましょう。

Gemini
Best for structured team frameworks, interview scorecards, and culture charters. Produces clear, implementable documents that can be shared with the team immediately.
結果元: Gemini 2.0 Flash · テスト済み Feb 15, 2026ChatGPT
Best for performance reviews and delegation frameworks. Writes professional documentation with the right tone for HR processes and creates practical handoff templates.
結果元: GPT-4o · テスト済み Feb 15, 2026Claude
Best for 1-on-1 preparation and conflict resolution. Handles interpersonal dynamics with emotional intelligence and provides mediation scripts that feel genuine rather than scripted.
結果元: Claude 3.5 Sonnet · テスト済み Feb 15, 2026Grok
Provides direct leadership and delegation advice without HR-diplomatic padding. Strong at identifying team dysfunction honestly, though less nuanced on interpersonal sensitivity and conflict resolution than Claude or Gemini.
結果元: Grok 2 · テスト済み Feb 15, 2026The best managers ask more questions than they answer. Use AI to generate coaching questions, not solutions. When your team brings you problems, asking 'What would you recommend?' grows their judgment faster than solving it for them.
Feedback is a gift only if it's timely. Performance reviews shouldn't contain surprises. If something needs to be said, say it within 48 hours. Use AI to draft the talking points immediately while the situation is fresh.
Measure outcomes, not hours. Tracking when people log on and off is surveillance, not management. Define clear deliverables and check results. AI can help you set measurable outcomes for every role.
