Product managers spend 38% of their time on documentation and communication, and only 18% on strategy and discovery. That ratio is backwards for most orgs, and fixing it is the most direct lever on PM impact (Scriptonia, 2026 internal data).
"The job is to make sure the right thing gets built, built right. Everything else is overhead. The question is how much overhead your processes require."
— Alex J., Principal PM at a growth-stage SaaS company
