Mitchell has worked for a very large company for three years. During lunch one day he stood at the elevator and read the building directory. He noticed that all of the accounting staff for his business was grouped on one floor, all of the legal personnel were on the floor above his, the CEO and his staff were on the top floor, the marketing and advertising departments on the floor under his, and the sales department on the floor under marketing and advertising. How is Mitchell’s business departmentalized?
