Another problem lies in people’s expectations of what planning & control software can do (see Chapter 8). Logistics software has not been used in an optimum way not least due to the false hope that computer aids can solve organizational problems — and all the human problems connected with them — without the company having to deal with such issues. However, planning & control can only be supported by information technology if — were resources in time and personnel unlimited — it could also be performed manually. That is why planning & control must be defined first as a company-internal and external system. Organizational processes, that is, operational organization, must first be studied and determined completely and precisely before any decisions can be made as to possible types of computer support.
