Configuration Management: Getting Started Presented By: Tony Iannetta, Evergreen Systems 1 Overview What is Configuration Management Why Configuration Management The Scope of Configuration Management What You Can Learn Getting Started Q&A What is Configuration Management: 3 Legs Three major components of the configuration management system 1. Configuration management (CM) is a set of policies, processes and disciplines for effectively identifying, controlling, auditing and managing configuration data 2. Configuration Management Data Base (CMDB) the data
repositories for the identification of all configured items (CIs), their attributes and their relationships to other CIs and the related IT data that supports the service management processes 3. Configuration Management Automation (CMA) the body of technologies necessary to effectively execute the auditing, controlling, visualizing and managing of all configuration data. What is Configuration Management In some sense, it is the natural progression of an IT Asset Management Database. Configuration Management Asset Management Inventory Management Why Configuration Management: Reason 1 Regulatory Compliance The Y2K of IT Regulatory compliance includes configuration integrity of the production environment The three pillars of configuration integrity: 1. 2. 3. Configuration Management and CM automation Change Management disciplines and automation Identity and access management (IAM) Implications 1. 2. Reduce IT audit and compliance efforts by 60-80% 80-90% fewer penalties
2005 Gartner, Inc. 29 November 2005/ID number G00131741 Why Configuration Management: Reason 2 Improving service quality Configuration management contributes to improving quality of service by maintaining the information necessary to ensure IT changes do no harm 87 % of all IT incidents are caused by poor change management. Increase speed and responsiveness to changes in the business AND Lowering cost of service delivery Configuration management contributes to lowering the cost of service by: Increasing utilization of existing IT resources reducing the investment in IT infrastructure 2005 Gartner, Inc. 29 November 2005/ID number G00131741 Why Configuration Management: Reason 3 Aligning IT with the business Configuration management contributes to improving alignment of IT with the business by Enabling service level uptime agreements Enabling rapid development of new services or changes to existing services as the market dictates Demonstrating the same rigor in IT that the business puts toward its customer. 2005 Gartner, Inc. 28 September 2005/ID number G00131333 Business Service Management (BSM) the real end game Stages of BSM of global $1B+ companies
Chaotic 35% - limited formal processes for managing IT Reactive 44% - IT inventory management implemented project by project with some basic ITIL processes Stable 14% - Integrated service delivery. IT asset management integrated with ITIL Proactive 7% - Business service framework Predictive 1 % - Resource allocation to business need Forester Research Inc.

recovery site. Capacity and Availability Management Use the CMDB to identify the CIs that contribute to a service and for Component Failure Impact Analysis (CFIA). Use data from the CMDB to plan the optimization of the IT infrastructure, to allocate the workload, and to develop a capacity plan. Service Level Management Needs information about services and the relationships between services and the underlying infrastructure CIs. Financial Management for IT Services Needs information about the use of services and CIs. The Scope of Configuration Management: The Process a set of policies, processes and disciplines for effectively identifying, controlling, auditing and managing configuration data CM Start Determine Policy, Strategy and Objectives for available information. Identify tools, resources and how information should be shared RFCs and Tasks Scope, Policy, etc. Selection and identification of CI structures into the CMDB including data owners, relationships and documentation.

Best Practices and Lessons Learned Executive Commitment Early, Continuous, Visible high-level sponsorship is critical Scope and Charter Start with easy wins and high-value efforts. Fully define set of definitions of terms and concepts Get assets under control first with policy adherence Consider IT Governance Strategy when developing Configuration Management strategy Marketing and Adoption Include stakeholders in policy and process design for buy-in Focus extra effort on cross-departmental processes and hand-offs Identify your job will get harder cases for extra training and support Over-communicate with all stakeholders Embrace conflict: it means people care and are paying attention Process CHANGE MANAGEMENT CHANGE MANAGEMENT CHANGE MANAGEMENT Build policies and processes for ongoing development Start with Asset Management (Receipt to Disposal) Technology Know what you have before you acquire more stuff Develop configuration management disciplines before automating Data Use the processes to drive the data requirements (just enough data) Data accuracy and control to ensure ongoing accuracy is critical Reduce the number of repositories Start with a wide and shallow approach for CI relationships Getting Started Begin by..
Establish a reasonable scope Document terms and concepts Documenting the current state of IT data and process Develop a product portfolio of current technologies Formulate the future state of IT data, process and technologies Formulate a roadmap and break it into doable phases Position for organizational change Establish a comprehensive foundation Establish data integrity Integrate with the enterprise Establish linkages Perform audits Configuration Management Questions?
