Client overview
Managing complex IT operations across one of America's largest cities
The client is a top-10 US city with citywide IT assets and no formal asset management process, creating significant compliance exposure. Its IT estate spans roughly 40,000 assets across city departments, with no centralized inventory, asset tagging, or structured warehouse operations to manage the hardware lifecycle.
Zensar was engaged for a 12-month, end-to-end ITAM transformation covering the full asset lifecycle, from process design through decommissioning and community repurposing.
Challenges
Fragmented IT processes, reactive incident management, and limited service visibility
Process standardization: Core service management processes needed to be aligned to ITIL v4 with consistent governance and operational controls across departments.
Critical incident readiness: A structured major incident management framework with defined escalation paths and communication protocols was needed.
Reactive problem management: Recurring incidents called for root cause analysis and proactive Problem Management to improve service stability.
Asset and workflow fragmentation: IT assets, procurement, onboarding/offboarding, and HR workflows needed standardized, automated, lifecycle-governed processes.
Limited operational insight: Executive and operational reporting needed KPI-based dashboards and service health monitoring to support data-driven decisions.
Solutions
A structured, ITIL v4-aligned transformation on ServiceNow
To achieve long-term operational excellence and service maturity, the client adopted a structured transformation strategy based on industry-leading ServiceNow and ITIL practices. They implemented ITIL v4-aligned processes, governance frameworks, and standardized delivery practices across departments. A structured major incident management framework introduced defined escalation paths, communication protocols, and recovery procedures. In contrast, problem management matured through the 5-why methodology for root cause analysis and proactive practices to reduce recurring incidents. Enhanced executive and operational dashboards, KPI-based reporting, and service health monitoring enabled data-driven operations.
ITSM transformation
Implemented incident, major incident, change, problem, service catalog, SLM, CMDB, ITAM, and self-service portal on ServiceNow.
Asset and software management
Implemented ITAM and SAM with asset lifecycle governance and automated procurement workflows.
Enterprise workflow transformation
Deployed standardized workflows and service catalogs for onboarding, offboarding, HR case management (HRSD), and workplace services.
Workplace and password reset automation
Automated IMACD (Install, move, add, change, dispose) catalogs and Active Directory password reset through self-service channels.
Solution enablers
ITIL v4 process standardization
ITIL v4-aligned processes, governance frameworks, and operational controls standardized service delivery across departments.
Major incident management excellence
A structured MIM framework with defined escalation paths, communication protocols, and recovery procedures.
Problem management maturity
5-Why root cause analysis and proactive practices focused on reducing recurring incidents.
Data-driven operations
Executive and operational dashboards, KPI-based reporting, and service health monitoring.
Business outcomes
The transformation gave client an operationalized enterprise ITSM platform: 9 core processes, a 98% change success rate, a reliable CMDB foundation, annual asset reconciliation across 54 departments, and 700+ knowledge articles supporting self-service. Workflow automation reduced manual effort and turnaround times, while IMACD catalogs and automated password reset improved fulfillment and user productivity. Client's strategic goals, including service excellence, user experience enhancement, data-driven decision-making, CMDB and service visibility, and intelligent operations, are supported by a phased roadmap: FY26 integration and service expansion (employee center migration, network service catalog), FY27 optimization (flow designer migration), and FY28 intelligent automation (ITSM Pro, predictive intelligence, demand and project portfolio management).
