A global enterprise customer running a multi-million-CI ServiceNow estate could no longer trust its CMDB. Four Dragons baselined CMDB health, stabilized Discovery, and delivered Service Mapping — moving the team from reactive firefighting to a governed roadmap targeting 90–95% CMDB health.
At a glance
- Client: A global enterprise customer (named client withheld under confidentiality).
- Estate: A multi-million-CI ServiceNow CMDB across a multi-cluster MID-Server environment.
- Engagement: CMDB remediation, Discovery stabilization, and Service Mapping, aligned to CSDM.
- Delivery model: AI-automated and human-supervised — AI agents handled the repeatable remediation while certified consultants owned strategy and architecture.
Key results
- CMDB health baselined across 430+ CI classes, with governance refocused onto the several-hundred-thousand principal-class CIs that actually matter — out of a multi-million-CI estate.
- 24 Service Mapping business-service maps delivered at a 92% approval rate, with roughly 70% of the pipeline already live and discovering against the CMDB.
- Discovery stabilized across a multi-cluster MID-Server estate — tens of thousands of daily can’t-classify failures remediated and redundant servers removed.
- A clear roadmap to 90–95% CMDB health within 3–6 months, replacing reactive firefighting with governed, measurable improvement.
The challenge
Years of unmanaged growth had left the CMDB unreliable. Discovery was generating tens of thousands of can’t-classify failures a day, CI data had drifted, business services were unmapped or stale, and the sheer scale of a multi-million-CI estate made it impossible to know which data could be trusted. The result was familiar: incident, change, and impact analysis ran on data the teams no longer believed, and effort went into firefighting rather than improvement.
The approach
- Baseline the truth. We measured CMDB health across 430+ CI classes to see exactly where completeness, compliance, and correctness were failing.
- Focus governance where it matters. Rather than boil the ocean, we refocused effort onto the several-hundred-thousand principal-class CIs that drive real service and risk decisions.
- Stabilize Discovery. We fixed MID-Server clustering, credentials, and probes across a multi-cluster estate, remediated tens of thousands of daily can’t-classify failures, and removed redundant servers.
- Deliver Service Mapping. We built business-service maps against real discovery data, validated them with service owners, and aligned everything to the Common Service Data Model (CSDM).
- Establish a roadmap and governance. We handed the team a sequenced roadmap to 90–95% health, with ownership, KPIs, and a data-certification cadence to keep it there.
The results
Within the engagement, the enterprise moved from an untrusted CMDB and reactive firefighting to a measured baseline, a stabilized Discovery pipeline, 24 approved service maps (92% approval, ~70% live), and a governed roadmap targeting 90–95% health in three to six months. Just as important, the capability stayed in-house: we upskilled the team so the improvement was sustainable rather than dependent on us.
Why it worked
Four Dragons is a ServiceNow services firm — not a product company — led by Ian Cox, a former ServiceNow employee with over a decade on the platform. Our AI-automated, human-supervised delivery model let AI agents carry the repeatable remediation load at scale while certified consultants owned the strategy, architecture, and the judgment calls — the combination that makes remediation at multi-million-CI scale practical.
