I’m structuring a 90-minute quarterly learning sprint for our CSMs and want programs that move renewals and NPS, not just theory. Any real results from CXPA, SuccessCOACHING, or Zendesk QA certifications, and how did you measure ROI? We run call reviews in Gong and house playbooks in Notion, so I’m looking for curricula we can map directly to those workflows.
