Build rapport

Use empathy and active listening to lower resistance before moving into sensitive facts.

Develop information

Ask purposeful questions, test accounts, and document reliable, actionable details.

Resolve ethically

Reach outcomes that are moral, legally acceptable, and defensible for the organization.
