Capacity Management

Process

The main activities involved in Capacity Management may be summarised as:

• Developing the Capacity Plan.
• Modelling and simulating various capacity scenarios.
• Monitoring the use and performance of the IT infrastructure.
• Demand Management.
• Creating and maintaining the Capacity Database (CDB).

The Capacity Management process may be subdivided into a series of sub-processes analysing the IT capacity needs from different points of view:

• Business Capacity Management: focusing on the future needs of users and customers.
• Service Capacity Management: this analyses the performance of IT services in order to ensure the agreed levels of service are met.
• Resource Capacity Management: which studies both the use of IT infrastructure and the trends to ensure that sufficient resources are available and that they are used efficiently.
