Large structures have long chains of command (how many levels of hierarchy there are from the factory to the general manager) and a narrow span of control (the number of people that individuals are responsible for in a company). One of the benefits of having some control is that there is a greater chance of getting promoted at your job, but lines of communication and messages may go unnoticed. M&S has many different functional areas such as finance, marketing, customer service, sales and human resources. Functional areas will work collaboratively with each other to achieve an end result. For example, the marketing team will work alongside the finance department when creating advertisements for M&S. The marketing team will choreograph the advertising while the finance team will find a way to finance the advertising. It is therefore crucial that departments work together to achieve an effective and efficient result.
