Different between narrow span of control and wide span of control?
Optimum span of control ranges between 3 and 9 depending on the complexity of the work supervised and the need for tight control. Narrow would therefore be 3-5, for example an infantry fire team (3). Wide would be 7-9 as in some business teams. With physical work as opposed to abstract work, such as shop floor work in a factory, span can sometimes be increased to as much as 30 without a productivity loss because outputs are predetermined.
