How to Use Prompts and Frameworks for Better Due Diligence

Prompt engineering isn’t just for AI. Use targeted questions and checklists to guide your research and conversations. For example, prompt your advisors with:

• “What are the three biggest operational risks in the current workflow?”
• “Which customer accounts contribute over 10% of annual revenue?”
• “Are there any off-balance-sheet liabilities not disclosed?”

Leveraging these frameworks helps you uncover what matters most, faster—and reduces the risk of overlooking critical details.
