An often-asked question in this regard is: "Do I have to change my organisational structure?" The question often crops up because the ITIL process approach means that processes have to be managed over more than one department within traditional hierarchical company structures. Some organisations have tried the 'matrix' organisational approach, but whatever structure you choose, there will always be benefits and disadvantages connected with each. Consider the following examples:
| + | the traditional role model |
| + | clear lines of communication |
| + | clear function and task descriptions within each department |
| - | may result in a bureaucracy if you describe procedures in too much detail |
| - | difficult to place process roles in this model |
| - | process approach will require a complex communication structure. |
