Technical Management is the function which is most similar to an organisational unit. It is here that the technical expertise is located in the form of personnel, and in many IT organisations, it is equivalent to the operation department or the infrastructure department.
The entire technical IT environment requires administration. If something goes wrong, it needs to be restored and if something new has to be set up, it needs to be designed and constructed. Performing these activities requires expertise in relation to all the products and components included in the IT environment. It is the responsibility of the Technical Management function that this expertise is available for the IT organisation.
