If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

What made the introduction easy or difficult?
Which next step needed explanation?
What feedback did you want afterward?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: referrers receive no confirmation of the introduction.
2. An unclear next step shows where a voluntary introduction lacks responsibilities or expectations. Clarify who contacts whom under the agreed process, without treating a referral as permission for unrestricted marketing contact.
3. Turn the requested improvement into a testable next step. One illustrative action is: send an appropriate acknowledgment and next step.
