MWITA-SBO-2026-004 · Evidence A · P1
Mandatory mentorship raised new sales agents' daily revenue by 19% and revenue per call by 12% during the first two months, while voluntary opt-in produced approximately zero average revenue gain.
What this does not establish
Applies to young new hires, inbound calls, a four-week mentoring program and digital subscriptions; COVID-19 curtailed the planned extension.
Counterevidence & uncertainty
Voluntary participation did not reproduce the mandatory-program revenue effect and neither treatment improved retention.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial or human outcomes.
