In our personal lives, surprises can be fun. In our business lives surprises are not usually welcome!
Good Capacity Management aims for a world of no surprises. More than any other aspect of the OGC ITIL® definition, it is the element concerned with looking forward and ensuring that we know what will happen, that there are no surprises.
Capacity Management aims to understand what an organization needs to achieve in the future, map this onto IT resources required to achieve those goals and provide a plan showing what IT resources are needed and when in order to achieve those goals.
