Expertise, quality and reliability are the signs of a good IT department’s efficiency. It must comply with various requirements, but often does not have enough employees, has little to no extra time and sometimes does not have the necessary technology. This means that an IT department usually works at full capacity every day, and additional tasks such as software development or large malfunctions will quickly overwhelm the department.
Another model is much more efficient: the IT department takes on external service providers, and hands over all tasks that do not necessarily need to be completed by internal employees. The entire company then benefits from more flexible capacity for routine IT work. External experts can even take over programming work that the internal IT department employees either do not have the time or skills to implement. Even complete development of new, company-specific applications is possible and is sensible in this model.
