An office space should reflect and promote an organization's values and ethos to both internal and external audiences. To evaluate how efficiently an office space is being used, one can measure metrics like occupancy density, shared workstations, and costs. Truly understanding office efficiency requires analyzing the three E's: efficiency in using space, effectiveness of how people work, and expressing the organization's brand. Productivity is maximized when the supply of office space and resources matches the demands of the organization and its employees.
