Capacity Management

Capacity Management needs to ensure that sufficient resources and performance is available to meet the demands of the business. Essentially, capacity management is a balancing act as it tries to balance the cost of supplying a service against the need for the service, as well as ensuring there is enough of the service to meet the demand. Simple Supply and Demand.. 101!

It has 3 areas of responsibility namely:

• Business Capacity Management
• Service Capacity Management
• Resource Capacity Management

Business Capacity Management takes the need and plans of the business, both current and future, and translates the information into requirements that can be used to extend or transform the service delivery and infrastructure. Managing, controlling and predicting the performance and capacity of services that are being delivered is part of both Service and Resource Capacity management. The usage of the end-to-end service and the workloads on that service forms part of Service Capacity Management, whereas Resource Capacity Management is concerned with the individual components of the service.

There are a number of similarities on each of the areas of responsibility, but each has a distinct difference, and that is Business Capacity Management is focused on the current and future business requirements, while Service Capacity Management is focused on the delivery of the existing services that support the business and Resource Capacity Management is focused on the infrastructure that underpins service provision,
