Semco SA is a Brazilian manufacturing company that saw significant increases in productivity and profits after adopting an unconventional management structure and company culture. Ricardo Semler eliminated top-down hierarchy when he became CEO in 1980, doing away with titles, job descriptions, and long-term planning. He divided the company into autonomous business units each led by a general manager. This empowered employees to make decisions and take on new roles and projects. As a result, workers took initiative to cut costs and generate new revenue streams. Semco's innovative approach was recognized internationally and profiled in hundreds of publications as a model for participatory management.
