A manager must consider the total work environment, including physical and social surroundings, to improve organizational performance. The physical work setting, such as layout, lighting and ventilation, impacts productivity. There is a complex relationship between management efforts to change the work environment, how workers perceive those efforts, and organizational efficiency. Today, space planners and organizational development experts collaborate to improve the physical work environment and organizational effectiveness. When evaluating the work environment, managers should consider factors like noise levels, workspace layout, lighting, and employee involvement in improvements.
