ITCM   VS ITAMSome Asset Managers consider Asset Management to be very similar to Configuration management.However there are differences:Asset management manages the financial life cycle of an Asset.Assets’ life cycle; right from the inception to the retirement/disposal phase. Assets are managed by Asset management ??? Not convinced that this is very important. Asset Requisition, Asset Procurement, Asset Inventory, Asset Maintenance, Asset Reporting, Asset Disposal. Configuration management is  Management / Administration of IT CI's  Operation assets - involves the management planning- CI identification and tracking - CI Control- CI Verification Example :- BUILDING CAN BE Asset but not a CI-  Server can be both an asset that can be tracked and by Configuration Management, since the server is an IT Asset in that should be tracked via Asset management since there is a cost involved.  

From the latin COM = With +   Figurare = Form .. With FORM   Form ActivitiesThe information in the CMDB is used for five basic activities: Planning: The CM plan covers the next three to six months in detail, and the following twelve months in outline. It is reviewed at least twice a year and will include a strategy, policy, scope, objectives, roles and responsibilities,  the CM processes, activities and procedures, the CMDB, relationships with other processes and third parties, as well as tools and number of CI categories to track in the CMDB determines the scope. The detail of the CI information is the depth. Identification: The selection, identification and labeling of all CIs which creates a parts list of every CI in the system. This covers the recording of information about CI's, including hardware and software versions, documentation, ownership and other unique identifiers. CIs should be recorded at a level of detail justified by the business need, typically to the level of "independent change". This includes defining the relationships of the CIs in the system. Control: This gives the assurance that only authorized and identifiable CIs are accepted and recorded from receipt to disposal. It ensures that no CI is added, modified, replaced or removed without the appropriate controlling documentation e.g. approved Requests for Change of a CI, updated specification. All CIs will be under Change Management (ITSM)control. Monitoring: Concerned with each CI throughout its life-cycle. It enables changes to CIs and tracking of their records through various statuses, e.g. ordered, received, under test, live, under repair, withdrawn or for disposal. Verification: The reviews and audits that verify the physical existence of CIs, and checks that they are correctly recorded in the CMDB and parts list. It includes the process of verifying Release Management (ITSM) and CM documentation before changes are made to the live environment. ITIL is part of the best practices for Service Management , Guidance for provision of quality IT services , which creates  value for IT Practitioners

Asset management, broadly defined, refers to any system that monitors and maintains things of value to an entity or group. It may apply to both tangible assets such as buildings and to intangible concepts such as intellectual property and goodwill. Asset management is a systematic process of operating, maintaining, upgrading, and disposing of assets cost-effectively, (American Association of State Highway and Transportation Officials). Alternative views of asset management in the engineering environment are: The practice of managing assets to achieve the greatest return (particularly useful for productive assets such as plant and equipment), and the process of monitoring and maintaining facilities systems, with the objective of providing the best possible service to users (appropriate for public infrastructure assets).
