Explaining the feasibility, extended development timeline, and additional costs for major specification changes requested by overseas clients during ongoing projects.
プロジェクト進行中に海外顧客が要求した産業用機器の大幅仕様変更について実現可能性、開発期間延長、追加コストを説明する場面です。
👨💼【Teacher / Overseas Customer】:
Thank you for meeting with me today. I need to discuss some critical changes to the equipment specifications we agreed on. We require additional functions and performance improvements for our production line.
（本日はお時間をいただきありがとうございます。合意した機器仕様について重要な変更を話し合う必要があります。生産ラインに追加機能と性能向上が必要です。）
🧑🎓【Student / Sales Representative】:
I understand your requirements. Could you elaborate on which specific functions and performance levels you need? This will help me consult with our technical team accurately.
（ご要望は承知しました。具体的にどの機能とどの性能レベルが必要かお聞かせいただけますか？技術チームと正確に協議するために役立ちます。）
👨💼【Teacher / Overseas Customer】:
We need the motor output increased by 15 percent and an automated monitoring system added. Can your technical team accommodate these modifications? We're concerned about the timeline.
（モーター出力を15パーセント増加させ、自動監視システムを追加する必要があります。貴社の技術チームはこれらの変更に対応できますか？納期が心配です。）
🧑🎓【Student / Sales Representative】:
Let me explain the situation clearly. First, our technical team can accomplish both modifications you requested. Second, the development period will be extended by 2 months to ensure quality. Third, the additional cost will be approximately 18000 USD due to specialized components and engineering hours.
（状況を明確に説明させてください。第一に、技術チームはご要望の両方の変更を達成できます。第二に、品質を確保するため開発期間が2か月延長されます。第三に、特殊部品とエンジニアリング工数により追加費用は約18000米ドルになります。）
👨💼【Teacher / Overseas Customer】:
2 months is longer than we anticipated. Can you accelerate the process somehow? We need to launch our new production line by the end of this year.
（2か月は予想より長いです。何とかプロセスを加速できませんか？今年末までに新しい生産ラインを立ち上げる必要があります。）
🧑🎓【Student / Sales Representative】:
I appreciate your timeline concerns. We can reduce the extension to 6 weeks if we assign additional engineers and expedite component procurement. However, this will increase the additional cost to 22000 USD. The risk is that quality validation time will be minimal.
（納期のご懸念は理解しております。追加のエンジニアを配置し部品調達を迅速化すれば、延長期間を6週間に短縮できます。ただし、追加費用は22000米ドルに増加します。リスクは品質検証時間が最小限になることです。）
👨💼【Teacher / Overseas Customer】:
What about the warranty period? Will these modifications affect the standard warranty terms we discussed earlier?
（保証期間はどうなりますか？これらの変更は以前話し合った標準保証条件に影響しますか？）
🧑🎓【Student / Sales Representative】:
The standard 2-year warranty will remain unchanged for the original specifications. For the modified components, we offer a 1-year warranty initially, which can be extended to 2 years after 6 months of stable operation monitoring.
（標準の2年保証は元の仕様について変更されません。変更された部品については、当初1年保証を提供し、6か月の安定稼働監視後に2年まで延長できます。）
👨💼【Teacher / Overseas Customer】:
I need to review these terms with my management team. Can you submit a formal proposal document with all the details we discussed today by next Monday?
（これらの条件を経営チームと検討する必要があります。本日話し合った詳細をすべて含む正式な提案書を来週月曜日までに提出していただけますか？）
🧑🎓【Student / Sales Representative】:
Absolutely. I will coordinate with our technical and legal teams to prepare a comprehensive proposal. It will include the modified specifications, timeline options, cost breakdown, and warranty terms. I'll make sure you receive it by Friday morning.
（承知しました。技術チームと法務チームと調整して包括的な提案書を準備します。変更仕様、納期オプション、費用内訳、保証条件を含めます。金曜日の午前中までに確実にお届けします。）
👨💼【Teacher / Overseas Customer】:
Thank you for your prompt response and flexibility. I look forward to reviewing your proposal. This will help us make an informed decision quickly.
（迅速な対応と柔軟性に感謝します。提案書を検討するのを楽しみにしています。これにより迅速に十分な情報に基づいた決定ができます。）
