Customers don't care about adoption metrics. They care about results. "100 users logged in" means nothing if revenue didn't increase. The shift from tracking adoption to engineering outcomes is the defining evolution of customer success in 2025-2026.

Outcome engineering means working backward from the customer's business goals to define success criteria, build measurement frameworks, and prove ROI in terms the CFO understands. It's the difference between "your team used Feature X 500 times" and "Feature X saved your team 12 hours per week, worth $150K annually."

In this topic, you'll learn to define outcomes collaboratively with customers, build measurement systems that capture real value, and communicate impact in language that drives renewals and expansion.
