The reference call, run on a standardized script
The exact structure Prevouched liaisons follow on a reference call during vetting. Published so agencies can prepare and buyers can run their own.
Before the call
Reference is sourced from the agency's last five engagements. At least two must be decision-makers, not engineering ICs.
Liaison sends the four questions in advance, in writing. References who decline to discuss specifics in advance are scored as a candor signal, not disqualified.
The four questions, in order
1. Walk me through the last engagement end-to-end. Scope, timeline, outcome, what changed because they were there.
2. Tell me about a moment the engagement was in trouble. How did the agency behave?
3. If you had the same project to do again with the same budget, would you hire them, and would your answer be different at 2× the budget?
4. What is the one thing this agency should fix before the next engagement?
Scoring the call
Question 2 is the highest-signal. References who cannot recall any moment of trouble are scored low on candor, regardless of glowing answers elsewhere.
Question 4 must produce a substantive answer. 'Nothing comes to mind' is recorded verbatim and treated as a coached reference.
Notes are filed verbatim. Paraphrasing is the death of a reference check.
- 01References get the questions in advance. Surprise is not the test.
- 02Question 2 (the trouble moment) is the call's centre of gravity.
- 03Coached references are detectable, recorded, and scored.
