IT lifecycles and processes

Here is an overview of the 2nd edition's process architecture.(click for larger)

 

Lifecycle definitions:

Application Service Lifecycle	The cradle to grave existence of a direct application of computing technology assets to a business problem. Example: Payroll system, Email service.
Infrastructure Service Lifecycle	The cradle to grave existence of a service which indirectly supports the application of technology to one or more business problems. Example: Network service, distributed hosting service, mainframe transaction processing subsystem
IT Asset Lifecycle	The forecasting, acquisition, operation, and disposition of a tangible IT asset. Example: Dell server w/particular serial #, Oracle database software license.
Technology  Product Lifecycle	The specification, choice, operation, maintenance, and removal of a class of assets. Example: SQL Server 2000, independent of any particular license. Compaq DL580, as a server type, independent of any specific unit.

Process definitions:

Accept Demand	Capture, prioritize, and authorize and track response to requests and identified needs for IT services. Example: Accept request for new functionality in an HR system module.
Execute Project	Within a boundary of time, scope, and resources, complete a set of activities (typically unique or at best semi-repeatable) resulting in a value-added end state delivery.  Example: Define requirements, build, test, and release new HR functionality.
Deliver Release	Coordinate the assembly of IT functionality into a coherent whole and deliver this package into a state where the customer is getting the intended value. May be a sub-process within Project, but not all Releases are governed by Projects, and some Projects may have multiple Releases. Example: 1st iteration of new HR functionality.
Complete Change	Capture, assess impact and risk, track approvals, and coordinate service requests (as needed) to change some controlled aspect of the IT environment. Example: Move new HR code from development source control library onto production server.
Fulfill Service Request	Capture, track, and ensure delivery of routine requests (typically not involving change control) for IT services.  Example: Provision access to the HR system.
Deliver Transactional Service	An individual, granular delivery of a given IT transaction. Example:  Look Up Employee.
Restore Service	Identify IT service outages, assign/escalate, and track through at least tactical remediation. Example: Restore HR System by rebooting application server.
Improve Service	Identify enhancement opportunity for IT system or capability, prioritize, assign, and track through completion. Example: Deploy HR System on redundant cluster.
Retire Service	Identify retirement opportunity for IT service, prioritize, assign, and track through completion. Ensure critical risk and compliance objectives (data preservation and/or media destruction). Example: Retire current HR system from vendor X as part of overall strategy to move to service from vendor Y.
