Here's Why You Should Start Estimating in Complexity Instead of Hours

Hour-based sprint estimates consistently run low due to social pressure and a fundamental misunderstanding: complexity and time are two separate dimensions. Estimating in story points (3, 5, 8, 13) shifts planning from individual defensiveness to team-wide problem analysis. Developers then estimate their own hours privately, making missed estimates a learning signal rather than a personal failure — and velocity provides the date ranges stakeholders need.
