Managed Testing Center of Excellence for a Leading Global Private Bank Saves US$ 2.45-Mn in Three Years

Client

Global Banking Major

The client is a global private banking entity that provides wealth management and cash management services, utilizing investment strategies and specialized services to help high-net-worth customers achieve their wealth aspirations. As part of enhancing their operations, the client partnered with Hexaware to implement a Managed Testing CoE focused on improving testing efficiency and system performance.

Challenge

Addressing Testing Inefficiencies and Coverage Gaps

The client needed to establish a Managed Testing Center of Excellence to perform IST/Regression UAT, improve test coverage, shorten test cycles for each release, improve key business system performance, shorten test cycles to reach time to market sooner, and standardize and centralize test cases, tools, and management to improve coverage.

Solution

Standardizing Processes and Centralizing Test Assets

The long-term engagement involved standardizing processes, automation, and centralizing test assets into a single repository. From a people perspective, socializing the mission of the Testing Center of Excellence to promote acceptance by business and project stakeholders was key to the initial success of the center.

Working closely with project and program leadership, Hexaware was able to forecast demand and reduce onboarding times to ensure all business guidelines met expectations and commitments. The standardization and operationalization of automation allowed Hexaware to extend test cycles, increase coverage, and trap defects earlier in the software lifecycle than previously possible. The replicability and scalability of the center allowed Hexaware to demonstrate success with an initial set of applications, while increasing application coverage 3-fold over a 24-month period.

The implementation included:

• Standardizing and introducing automation accelerators to increase test coverage and shorten execution time
• Instituting a test data management framework to remove a major bottleneck in the software lifecycle
• Introducing the early defect detection framework, taking over test environment management to reduce SDLC bottleneck, shortening test cycles to 15-21 days to meet market demands
• Acquiring business acumen to ensure TCOW coverage of user acceptance testing

This approach incorporated test automation services tailored as test automation for banks, enabling:

• Test acceleration by >35%
• Automation architecture optimization by 40%
• Extended 16X5 test cycles
• Enhanced testing coverage >96%
• Resource demand management of 100%
• 20% enhanced throughput through shared synergies
• >90% test environment availability
• >90% test data availability
• 100% reduced rework
• Assured accuracy <1% defect leakage
• 25% early defect detection rate 

Benefits

Achieving Cost Savings, Improved Coverage, and Operational Efficiency

• Test coverage increased from 75% to 96% by implementing the APT framework 
• Implemented a scalable Managed Testing CoE, ramping up from 7 to 21 applications in 24 months 
• Test automation suite for regression led to 75% cost savings and a 60% effort savings 
• 99% of defects unearthed in the IST phase 
• Ready-to-use mobile, performance, and automation frameworks led to overall year-on-year savings of 15% 

Additional benefits included enhanced productivity, accelerated test cycles, skilled talent pool, flexibility, process maturity, reduced cost of ownership, flexible resource pool, assimilation & shared synergies, reusability, total cost of quality, reduced rework, release confidence, standardization & repeatability, scalability, product maturity, demand management, and knowledge management.

Summary

Through the establishment of a Managed Testing Center of Excellence, the global private bank achieved significant improvements in test coverage, cycle times, and defect detection, resulting in cumulative savings of US$2.45 Mn over three years while scaling testing across more applications. the integration of test automation services, test data management, and user acceptance testing processes, customized for banks, delivered enhanced reliability, cost optimization, and capability improvements, positioning the client for faster time to market and operational excellence.
