In addition to know-how, quality and reliability, a good IT department is, above all characterized by efficiency. It has to meet a wide range of requirements, but usually has too few employees, little time and sometimes not even the necessary technology. The full utilization of an IT department with its daily business is more the rule than the exception. Additional tasks, such as software development or major operational disruptions quickly lead to overload.
A different model is much more efficient, in this model, the IT department takes over the coordination of external service providers and assigns them all those tasks that do not necessarily have to be performed by internal employees. In this way, the entire company benefits from more and more flexible capacities for routine IT work. External experts can also perform programming work for which the internal employees of the IT department lack the time or know-how. Even the complete development of new, company-specific applications is possible and sensible in this constellation.
