Imagine a company. It could be an American manufacturer of home
computers. Try to imagine, too, all the things such a company must be
able to do: purchasing from suppliers, assembling and packaging the
parts, preparing manuals and marketing plans, selling the products.
The company also has a large number of support functions. Someone
must look after the well-being of its employees, new staff must be
hired, people must be paid, the place must be cleaned, and a canteen
must work to feed everyone. There is an entire financial function,
ensuring that the crediting and debiting of banks, suppliers, owners,
and customers runs smoothly. Finally, there are all the planning
processes related to product lines and customer groups on which the
company has chosen to focus.
