Some of the activities of Capacity Management are defined in the context of three sub-processes consisting of Business, Service and Component Capacity Management. Besides these, there will also be discussion of the operational activities required as well as the techniques that are utilized in various forms by the three different sub-processes.
Business Capacity Management:
* Manages Capacity to meet future business requirements for IT services
* Identifies changes occurring in the business to assess how they might impact capacity and performance of IT services
* Plans and implements sufficient capacity in an appropriate timescale
* Should be included in Change Management and Project management activities.
Service Capacity Management
* Focuses on managing ongoing service performance as detailed in the Service Level Agreements
* Establishes baselines and profiles of use of Services, including all components and sub-services that affect the user experience
* Reports to the Service Level Manager and Service Owner regarding end-to-end service capacity, performance and utilization.
Component Capacity Management
* Identifies and manages each of the individual components of the IT Infrastructure (e.g. CPU, memory, disks, network bandwidth, server load)
* Evaluates new technology and how it might be leveraged to benefit the organization
* Balances loads across resources for optimal performance of services.
All three sub-processes collate their data and for use by other ITSM processes, primarily Service Level Management and Financial Management.
