The document discusses Business Service Management (BSM), which is defined as the discipline dedicated to the holistic management of services as corporate assets in an organization. It proposes a BSM Framework consisting of four clusters: 1) Service Lifecycle Management covering all stages from initiation to retirement, 2) Service Value Management ensuring business value creation through services, 3) Service Relationship Management integrating customers and suppliers, and 4) Service Enablement supporting the other clusters through quality, data and technology management. The core focus of BSM is presented as managing a service throughout its lifecycle from analysis and design to implementation, operation and retirement.
