The balancing act of Capacity Management
In coordination with the processes of Financial Management and Demand Management, Capacity Management seeks to provide a continual optimal balance between supply against demand, and costs against resources needed.
This optimum balance is only achieved both now and in the future by ensuring that Capacity Management is involved in all aspects of the Service Lifecycle. When this doesn’t occur Capacity Management only operates as a reactive process, with limited benefits being delivered as a result.
Capacity Management when used reactively
Capacity is only implemented when disruptions begin to occur as demand has exceeded supply. While the implemented capacity does work to resolve the disruptions, there are some consequences to this type of reactive behavior including:
* IT infrastructure components being purchased that don’t optimally fit the requirements or architecture
* Budget overruns for the unforeseen and unanticipated purchases
* Periods of time where there are potentially large amounts of excess capacity
* Reduced customer and user satisfaction with the affected IT services
* A general negatively affected perception of the IT organization as a whole.
