Build principles
A narrow product should have a narrow operating model.
Define one job
Each product starts with a recurring operational problem and a specific buyer.
Self-service first
Setup and routine use should not depend on a sales-led implementation team.
Operate what ships
Reliability, maintenance, and support remain part of product engineering.
