Configuration Management
• Benefits– It is the glue that ties Service Management processes effectively
• Key Enabler– Better Incident Management– Effective Problem Management– Proper Change Management– Efficient Event Management– Accurate Cost Management – Accurate Capacity Management– Enables Automated Release and Deployment– Asset Management (HAM, SAM)– Service Level Management – Service Request Automation

Configuration Management SystemCMS (CMDB)
Effective Configuration Management requires• Configuration Management System• Contains all the Configuration Items (CIs )• Maintains a meaningful set of attributes and relations for each CI• Seamless Integration with other SM processes• Continuously updated CMS• A well defined Service CI Model• A well defined Configuration Management Process
• Tools to manage and maintain CIs• Effective Reporting Capabilities• Right sized Service Models• Process /Service Requirements to CI Mapping(Class, Attribute and
Relationship)

Why is it so difficult?
• Developing a CMS is too Complex• No Standardized CMS Models • IT Environments are becoming increasingly complex• No one tool that does all • Requires continued analysis, development and integration

Who Should Implement?
8
Large Number of CIs
• A reasonably large number of Cis• CI count > 2000• A good mix of CI types > 10• A sizable Attribute Set to use• Well defined CI to CI
relationships
9
Service Mix
• Good mix of services that own the CIs
• At least 3 services• Well defined service to
service dependency• Well defined service impact
models
10
Management Buy In
• Dedicated Config Mgmt. Process Owner• Need a Development team• Periodic assessment of gaps • Continuous CMS augmentation• Auto Discovery tools
11
CMS Implementation Strategy
12
Think Big
• Envision the end-state• CMS will evolve overtime• Design CMDB model well • Detailed CI Relationship• Service to Dependency modeling • Well defined Service models• Use extensible CMDB models• Right toolset to collect and build
cmdb
13
Plan - Incremental
• Avoid a multi year big bang approach
• Implement the most used pieces of cmdb first
• Select two but not more than 4 services in the initial phase
• Define the Service Model first to lay the structural foundation of the cmdb
• Iteratively add more CIs and end state complexity
14
Manage
• An unmanaged/un-governed CMS will lead to• Unreliable CI data• Incorrect metrics• User frustration• Inconsistent CI and Service
Model• Continuous Improvement • Metrics to manage data
quality• Continued Gap Analysis• Effectively integrating new
services and technologies• Keeping the CMS current
