This document discusses human scale in work organizations. It defines the ideal size of whole work teams as between 20-39 members for optimal effectiveness. Larger teams should be split into multiple units, while smaller teams can be clustered together. The ideal size is impacted by factors like technical complexity, social complexity, and rate of change. Jobs should be designed so that individuals are not responsible for all process steps in a team, but rather have distinct roles. Finally, human scale must be considered at all levels from individual jobs to departments and the overall organization.
