European MSP
MainStack led a full-scale ITSM modernization for one of Europe's largest Managed Service Providers. The engagement spanned service management redesign, CMDB rebuilds, and automation deployment across 20+ regions.
The client's legacy ITSM environment had grown organically over a decade, resulting in fragmented processes, unreliable reporting, and escalating operational costs. MainStack was brought in to architect a resilient, scalable foundation.
[ Challenge ]
The MSP served enterprise clients across 20+ countries with a ServiceNow instance that had accumulated years of technical debt. Several critical issues needed to be addressed before any modernization could begin.
- Fragmented ITSM Processes. Each region had developed its own workflows, categorization schemes, and SLA definitions. There was no single source of truth for incident or change management, making cross-region reporting nearly impossible.
- Unreliable CMDB Data. The Configuration Management Database had less than 40% accuracy. Discovery tools were misconfigured, manual CI entries were outdated, and there was no reconciliation process in place.
- Report Generation Bottleneck. Monthly ITOM reports required 3-5 days of manual data aggregation from multiple sources. Leadership decisions were consistently delayed by stale data.
- Escalating Operational Costs. Duplicate tooling, redundant integrations, and manual workarounds had pushed operational costs 40% above industry benchmarks for an MSP of comparable size.
- Knowledge Silos. Platform knowledge was concentrated in 2-3 individuals per region. Staff turnover created repeated capability gaps and inconsistent service delivery.
Without addressing these foundational issues, any modernization effort would have been built on unstable ground. The client needed an architect-led approach that fixed the data layer before touching the UI.
[ Approach ]
MainStack deployed a single lead architect who owned the engagement end-to-end: from assessment through delivery and knowledge transfer. The approach was phased to minimize disruption while delivering measurable value at each stage.
- Platform Health Assessment (Weeks 1-2). We ran our proprietary CSDM/CMDB diagnostic across the instance, scoring data quality, process maturity, and integration health. This produced a prioritized remediation roadmap with effort estimates for every finding.
- CMDB Foundation Rebuild (Weeks 3-6). We redesigned the CI class hierarchy, implemented proper discovery patterns, and established automated reconciliation rules. CMDB accuracy moved from 40% to 92% within the first month.
- Process Standardization (Weeks 4-8). We consolidated 20+ regional workflow variants into a single governed ITSM process model. Incident categorization, change risk assessment, and SLA definitions were unified across all regions.
- Automated Reporting Pipeline (Weeks 6-10). We built real-time ITOM dashboards replacing the manual reporting process. What previously took 3-5 days now updates automatically, giving leadership instant visibility into operational performance.
- Knowledge Transfer and Enablement (Weeks 8-12). We delivered hands-on admin training, created operational playbooks, and conducted code reviews with the internal team. The goal: embedded capability through our operator model so the team grows stronger with every engagement cycle.
The phased approach ensured the client saw measurable ROI within weeks, not months. Each phase built on the previous one, creating a compounding effect that accelerated delivery.
