9 Discovery tools and Trusted CMDB The CMDB stores: s + Relationships Build a model and communicate Discovery tools help CMDB automation Standard interfaces may not be fit for purpose Data ownership is key for CMDB accuracy Only store the information you can control Enable all other ITIL processes to access the data they require Don t compromise! 9 Fox IT 2007

10 Building the Data Model Use a proven methodology (Fox PRISM) Get help and advices Construct the PURE DATA MODEL Design the ETITY RELATIOSHIP DIAGRAM Opt for a Top Down or Bottom Up approach Do not consider any products at this stage! Define the attributes List of mandatory attributes only Plan for links to external data source wherever possible Define the lifecycles What process will be used for each status 0 Fox IT 2007

18 CMDB Enabler the facts on proprietary technology Proven methodology: FoxPRISM Adaptable to many ITSM applications Adaptable to any data sources Integrate virtual components Integrate a pure data model (allow not to be constrained by product) Flexibility to manage data quality issues while providing the means for quality improvements Ownership and support can be transferred to the customer o license to purchase 8 Fox IT 2007

20 Steps to define a data source: Manual Automatic discovery Configuration and setup efforts How do you manage changes How do you manage obsolete information Can you manage the virtual components Is there an owner for the virtual components Can you access the complete information on a given? URL Security Limit the number of attributes to what is absolutely necessary and the one which need a quick access for the Desk for example. Identify which reports or flashboards are needed from within the CMDB tool for quick analysis. More complex analysis may be addressed by specialized reporting tools. For example, if you have Business Objects, the Universe may take in account the complete Virtual CMDB. 20 Fox IT 2007
