Case Study: Leading International Airline achieves 50% application reduction and 30%+ IT savings with HCL Prizm®

Leading International Airline - Customer Case Study

The customer, a leading global airline operator based in the APAC region with 20,000+ employees and services to 117 destinations, faced fragmented IT and poor service management: limited portfolio and cost visibility, 12 siloed support teams, low first-line resolution, long turnaround, weak incident processes and misaligned prioritization. HCL was engaged to simplify and modernize the application landscape, conducting Application Portfolio Assessments and IT service-management maturity assessments using its Prizm® automated web-based tool.

HCL used Prizm® to discover the AS‑IS portfolio, map dependencies, compute application health and TCO, and recommend rationalization and re‑engineering across technical, functional and management dimensions. The program delivered enhanced visibility and dashboards, budget rationalization and a scalable platform, with measurable outcomes including over 30% savings in targeted areas, more than 50% reduction in the application landscape (with ~60% portfolio reduction opportunities noted), >25% IT spend reduction in identified clusters, ~20–25% cycle‑time reduction and major legacy footprint reductions — improving cost control, productivity and agility.
