   4.3.4.1 Business Capacity Management
   This sub-process translates business needs and plans into
   requirements for service and IT infrastructure, ensuring
   that the future business requirements for IT services are
   quantified, designed, planned and implemented in a
   timely fashion. This can be achieved by using the existing
   data on the current resource utilization by the various
   services and resources to trend, forecast, model or predict
   future requirements. These future requirements come from
   the Service Strategy and Service Portfolio detailing new
   processes and service requirements, changes,
   improvements, and also the growth in the existing
   services

   4.3.4.2 Service Capacity Management
   The focus of this sub-process is the management, control
   and prediction of the end-to-end performance and
   capacity of the live, operational IT services usage and
   workloads. It ensures that the performance of all services,
   as detailed in service targets within SLAs and SLRs, is
   monitored and measured, and that the collected data is
   recorded, analysed and reported. Wherever necessary,
   proactive and reactive action should be instigated, to
   ensure that the performance of all services meets their
   agreed business targets. This is performed by staff with
   knowledge of all the areas of technology used in the
   delivery of end-to-end service, and often involves
   seeking advice from the specialists involved in
   Component Capacity Management. Wherever possible,
   automated thresholds should be used to manage all
   operational services, to ensure that situations where
   service targets are breached or threatened are rapidly
   identified and cost-effective actions to reduce or avoid
   their potential impact implemented.

   4.3.4.3 Component Capacity Management
   The focus in this sub-process is the management, control
   and prediction of the performance, utilization and capacity
   of individual IT technology components. It ensures that all
   components within the IT infrastructure that have finite
   resource are monitored and measured, and that the
   collected data is recorded, analysed and reported. Again,
   wherever possible, automated thresholds should be
   implemented to manage all components, to ensure that
   situations where service targets are breached or
   threatened by component usage or performance are
   rapidly identified, and cost-effective actions to reduce or
   avoid their potential impact are implemented.
   There are many similar activities that are performed by
   each of the above sub-processes, but each sub-process
   has a very different focus. 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 Component Capacity
   Management is focused on the IT infrastructure that
   underpins service provision. The role that each of these
   sub-processes plays in the overall process and the use of
   management tools is illustrated in Figure 4.9.
