Measuring Duplicate CI Reduction with Now Assist for CMDB – Best Practices?

[Snikhat]

Hi Community,

We are using Now Assist for CMDB to identify and remediate duplicate CIs and would like to measure its effectiveness and demonstrate business value to management.

I am looking for recommendations on the following:

1. How do you measure the number of duplicate CIs before and after remediation?
2. Which CMDB Health metrics or reports do you use to track duplicate reduction over time?
3. Do you report on:
   • Total duplicate CI count removed?
   • CMDB Correctness Score improvement?
   • Number of de-duplication tasks completed?
   • Reduction percentage month-over-month?
4. Are there any out-of-the-box dashboards or Performance Analytics indicators that help visualize duplicate CI trends?
5. How do you present the results to leadership or management to demonstrate the value of Now Assist and CMDB data quality improvements?  

   Example:

   • Duplicate CIs Before: 1,250
   • Duplicate CIs After: 320
   • Reduction: 74%
   • Correctness Score: 82% → 95%

   I would appreciate any examples of reports, dashboards, KPIs, or management scorecards that have worked well in your organization.

   Thanks in advance!
