Observability, CMDB, and event response that actually reduce pages.

ITOM is where ServiceNow earns back its licence cost — or fails to. We rebuild CMDBs that stay accurate, configure Event Management that cuts alert noise, and wire AIOps correlation that holds up under production load.

What it is

IT Operations Management

ITOM (IT Operations Management) covers Discovery, Service Mapping, Event Management, and the AIOps layer above them — all anchored on a working CMDB. Without ITOM, ServiceNow is a ticketing system. With ITOM done right, it becomes the hub your SRE and platform teams run the estate from.

When we recommend it

Fit signals.

  • You have an observability stack (Datadog, Splunk, New Relic) but alerts still reach humans
  • CMDB accuracy is 'fine' — but nobody trusts it for change impact analysis
  • MTTR is creeping up despite investment in monitoring
  • You're planning a cloud migration and need asset + service topology you can trust
  • You've tried AIOps once and it generated a lot of false-positive incidents
When it isn't the right call

Honest tradeoffs.

  • You don't have a team to operate ITOM post-go-live — it's not set-and-forget
  • Your environment is fully SaaS with no self-managed infrastructure (the value case is thinner)
Capabilities

What we deliver in ITOM.

Every capability below is practiced across multiple production engagements — not a scoping checklist.

Discovery & CMDB

  • CMDB architecture + CI class design
  • Discovery rollout (agentless + MID + cloud APIs)
  • Service Mapping for business-service topology
  • Data quality (Identification & Reconciliation rules)
  • Source-of-truth integration — Terraform, ArgoCD, AWS Config

Event management

  • Ingestion from Datadog, Splunk, Prometheus, vendor tools
  • Alert correlation + deduplication rules
  • Event-to-incident orchestration with suppression windows
  • Impact analysis based on Service Mapping

AIOps

  • Baselining + anomaly detection tuning
  • Correlation groupings (text, topology, temporal)
  • Auto-remediation playbooks with human-in-the-loop
  • Metrics — MTTD, MTTR, alert-to-incident ratio, noise score

Cloud Operations

  • AWS, Azure, GCP discovery and cost visibility
  • Cloud Insights dashboards for FinOps reviews
  • Container inventory (EKS, AKS, GKE)
  • Serverless + function-level asset tracking
Engagement patterns

The shapes this work
usually takes.

CMDB rebuild

Typical: 10–14 weeks. Most common ITOM engagement. We fix the data model, discovery, and reconciliation before anything else.

Event Management rollout

Typical: 8–12 weeks. Connect monitoring tools, tune correlation, cut alert noise by 60–80%.

AIOps pilot → production

Typical: 12–16 weeks across two services. Start narrow, prove the delta, expand with evidence.

ITOM managed service

Monthly. Noise hygiene, CMDB quality monitoring, roadmap facilitation, upgrade management.

What goes wrong

Pitfalls we've seen
and how we avoid them.

CMDB as archive

Data loaded once, never maintained. We make source-of-truth integrations a day-one rule, not phase-two stretch.

Correlation by hope

Default correlation rules left enabled; false positives erode trust. We tune rules to your actual topology before go-live.

AIOps as magic

Teams expect AIOps to fix their monitoring. It amplifies what's there — including the noise. Clean the source first.

Service Mapping neglected

Without mapped business services, impact analysis is guesswork. We do Service Mapping as part of every ITOM rollout.

FAQ

Common questions about ITOM.

Sometimes. ITOM's value is correlation, CMDB-grounded impact, and service-mapped incidents — not metrics collection. Keep your observability tools; use ITOM to route, reduce, and orchestrate. If your SRE team isn't asking for it, you don't need it.
