ServiceNow CMDB Managed Service

A CMDB doesn't stay accurate on its own

Even well-designed CMDBs degrade over time, and the trigger is usually a staffing decision rather than a technical one.

On one estate, the configuration management lead was made redundant and replaced with someone with no wider ITSM background. Within months, the CMDB stopped meeting the needs of the incident and change processes that depended on it: incidents took longer to resolve, more changes failed, and the processes that used to trust the data started working around it instead. Untangling that cost more in consulting fees than the saved salary ever recovered. The same pattern plays out at CI level in what happens when CI owners leave.

Systems are updated.

Infrastructure changes.

New services are introduced.

Without ongoing, specialist management, data becomes outdated and trust in the CMDB disappears well before anyone notices it happening. Completeness, correctness and compliance, the 3 Cs of a CMDB, are the first things to slip.

Continuous data monitoring

Ongoing data validation and correction

Governance and process management

Regular optimisation of discovery and integrations

This ensures your CMDB continues to deliver value over time. For how the whole model fits together, see what a CMDB is and how it works.

The governance we run is set out in CMDB best practice, and progress is reported through a CMDB health dashboard. Ownership gaps are one of the costs of leaving this unmanaged, as unknown CI owners driving up IT spend shows.

How a managed service starts

We don't take over a CMDB we haven't measured. The service runs in four phases, and you agree each one before it begins.

Baseline. A two-week CMDB health baseline scores which configuration items are trustworthy and which are guesses. The CMDB health check page explains what you receive.
Stabilise. We fix the causes the baseline finds, such as weak identification rules, competing reconciliation sources, duplicate CIs and missing owners.
Run. We operate the process day to day: ownership certification, change gates, exception handling and the links between change, incident and the CMDB.
Assure. We report against agreed key performance indicators (KPIs) in a form your change advisory board can use, and review them with you.

On one broadcast estate, the configuration management lead was replaced by someone who didn't understand the wider IT service management (ITSM) processes. The CMDB stopped meeting those processes' needs, incidents took longer to resolve and more changes failed. Correcting it cost the client over $100,000 in consulting fees. We were then hired to run the process as a managed service.

Managed service questions

What does a ServiceNow CMDB managed service include?

It covers ownership and certification of configuration items, data quality work (de-duplication, normalisation and reconciliation), oversight of Discovery and integrations, the links to change and incident, and regular reporting.

Do you replace our team?

We can work alongside your process owners or run the process in full. Which fits depends on your estate and your people, and we settle it at the initial consultation.

How do we start?

With the health baseline. It gives both sides an agreed picture of the data before any commitment to run it.

How is the service priced?

It is scoped against your estate at an initial consultation, so we can price the work you need and nothing else.

Book a meeting with a consultant, or start with a CMDB diagnostic call.

Configuration item lifecycle (creation, updates, retirement)

Data completeness, compliance and correctness

Deduplication and data consistency

Relationship accuracy

Discovery monitoring and optimisation

Why organisations choose managed services

On one broadcast estate, configuration management was treated as low-skill work and moved to a low-cost offshore team after the internal specialists were made redundant. Data quality fell quickly. Discovery scans ran at inappropriate times, invalid data drove poor change impact analysis, and multiple major incidents followed, including a probing sweep that took down delicate broadcast equipment. Advertisers pulled out as outages spread across channels.

Many organisations recognise the pattern before it gets that far:

Need to reduce operational cost, but without cutting the expertise the CMDB actually depends on
Don't have dedicated configuration management specialists
Don't have budget to build and retain that capability in-house
Are already dealing with data quality issues a generalist team won't recognise

Our managed service provides specialist expertise on an ongoing basis, without the redundancy risk of building an internal team that depends on one or two people.
