Cover page of a book titled "Capacity is the Constraint: Designing Human-Sustainable Systems in Complex Environments" by Natasha Dorsey, published in 2026.

Key Takeaways

  • Capacity, not effort or buy-in, is the primary constraint in complex human systems

  • Systems often appear stable because they rely on invisible over-functioning

  • Sustainable performance requires structural design, not additional individual adaptation

Capacity Is the Constraint

Designing Human-Sustainable Systems in Complex Environments

These systems brief outlines a capacity-aware framework for understanding why burnout, attrition, and implementation failure persist even in well-intended organizations, and how system design can address these challenges directly.

Rather than focusing on individual resilience or motivation, the brief reframes performance as an outcome of structural alignment between demand and human capacity.

This brief is intended as a decision-support resource, not a proposal or program.
