I have been working on a comprehensive data dictionary for our CMDB, along with documenting the following, as it pertains to attributes that are included in a classification that is considered in-scope for lifecycle management.
- Hint/Attribute Definition
- Is the attribute in-scope for use/does it provide purpose? (this obviously is mostly for out of the box attributes like fault count)
- What is the authoritative system of record for the attribute (sometimes this is better defined at the classification layer)
- Should the field be displayed on the form
- Is the attribute discoverable (y/n)
- Does the attribute need to be included in an audit/verification plan and if so, does it roll up to accuracy or completeness.
- What is the parent CI classification data source for the individual attribute? (i.e., cmdb, computer, server, network gear, etc.)
I would be more than happy to share this if you would like to contact me offline.
There are lots of areas for maturity within this framework, but this help compartmentalize future activities.
In addition, while we are currently storing the information we are gathering outside of ServiceNow (with the exception of the hint, our goal is to incorporate it back into ServiceNow, although this will understandably require custom development.
