By Michele Hudnall Mar 13, 2008 The ability to understand relationships and dependencies across IT components, applications and services has long been desirable for IT organizations and it is the promise of configuration management database (CMDB) projects. The accuracy of data that application dependency mapping tools provide, in combination with the need for higher quality configuration data to improve ITIL processes of incident, problem and change, are part of a collection of reasons why CMDBs grew so explosively over the last 12-18 months. The catalyst for CMDB projects is simple and the benefits are a tangible reality. If IT understands infrastructure relationships and dependencies they are better able to control change and manage the impact of change when it does occur. Patch management is a good case in point. A recent Computerworld survey found that two-thirds of Oracle DBAs dont apply security patches, primarily because they cant understand the impact installing a patch will have on the database service. The model of information about IT infrastructure components that a CMDB provides enables IT to understand the interdependencies about components in the context of the service. The DBA in the paragraph above for example, can see a holistic service view of the database application prior to installing a patch. This enables the DBA to understand the business impact a patch may have on other IT components and by extension, the service and take measures to prevent any adverse effects prior to implementation. While the improvement to IT service quality in this anecdote is highly desirable, it understates the magnitude of a CMDBs value proposition: to provide a more flexible, agile and resilient IT infrastructure that is truly aligned with business objectives. The ability to control change and manage impact means IT can respond quickly and as a strategic partner to a number of business demands, including the following:
The business case for a CMDB project is compelling, however the implementation can be a bit more challenging. To that end, below are 10 tips for a successful CMDB: 1. The 4 Ps A good chef knows that cooking up something appetizing is a combination of culinary skill, a time-tested recipe and fine ingredients. The best chef with the perfect recipe cannot even hope for a delicious outcome if the ingredients are lacking. Likewise a CMDB is about the ingredients or as ITIL says people, process, products and providers. A CMDB implementation requires organizational buy-in, a proven methodology for implementation and best-of-breed technology. 2. Its what you do with the data 3. Data quality over quantity A successful CMDB is not contingent on data its contingent on the right data. Be sure to identify the relevant data and proper process for accessing it. A CMDB should tie together carefully selected silos of information that model a service in its entirety. This makes what was mere data more accessible and meaningful, and in turn, transforms data into the information required to control change and manage the impact of change. 4. Dont get hung up on a database A principle reason the CMDB disguises itself on the pages of an asset management RFP is because its a high-profile buzzword thats easier to justify. However asset management is more akin to an inventory audit, while a CMDB is about relationships among physical or logical items that comprise the service IT delivers to the business. More importantly, its about the impact a break in those relationships has upon users. Asset management is just one of many important data sources in a federated and heterogeneous IT infrastructure.

Clearly define an end-state Just like a purpose is required to set the vision for the project, a CMDB also needs to have a clearly defined end-state. An end-state can serve as a trigger point to move a project into the next phase of implementation, for example once youve successfully modeled your SAP application in the CMDB, you move on to other critical applications such as CRM or order processing. Both the CMDB designer and user need to be included in building consensus around this point and it boils down to answering one simple question: how will you measure success? 6. Allocate enough resources 7. Just enough CMDB Forrester Research advocates a methodology called just enough CMDB. This can be accomplished by focusing on a critical service, a given domain or even a line of business. Take a top down approach and avoid trying to model every service or application in your enterprise. Choose carefully because early success will help garner the support and acceptance required to roll the CMDB project to other areas. 8. Build in flexibility and modularity 9. Dont let perfect get in the way of good 10. Dont wait to get started Conclusion While the urgency to start a CMDB projects is understandable IT should be on alert for lessons learned from other concurrent or previous CMDB implementations. The CMDB could conceivably prove to be the most important acquisition of the IT enterprise for the foreseeable future. Michele Hudnall is a former-META Group analyst and is currently the director of service management for BSM vendor Managed Objects, which is one of five vendors in the industry that meet Gartners functional requirements to be classified as a CMDB. She also sits on the board for the US-chapter of the IT Service Management Forum itSMF. |
