Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets

Business Challenges
The client’s day-to-day operations were heavily reliant on offline, time-consuming processes, legacy systems, and applications.
They had set the following objectives for themselves:
Growth and competitiveness within the financial services business required a new approach to IT. Legacy modernization was a big bottleneck. The major challenges that need long-term solutions included
Drive operational efficiency to help the client gain a competitive advantage
Improve quality of services by focusing on value additions and continuous improvements
Migrate the business with minimal impact to their end customers
Provide a transformation roadmap
The high-level scope for different line of business were:
Business to Consumer
Business to Business
• Customer Information Management • Query resolution • Payments and Billing Management • Number port out or Transfer request handling • Value added Services
• Billing and Invoicing • Escalation Desk Management • Customer information Management
• Payment processing • Invoice Processing • Refunds validation and processing
Finance
The need to increase the pace of innovation to provide first-class service to customers
The operations team was spending a lot of time in the maintenance and debugging of the system
The development team took months to release new software to production
Insufficient capacity in the system to meet the increasing demand from end customers
Need for enhanced monitoring capabilities to identify and fix issues promptly
Our Solutions
To meet the overall objective of migrating 100+ back-office processes, 200+ subprocess and 200+ FTEs, Hexaware focused on delivering a seamless project with minimal issues and slippages.
Hexaware, an AWS Advanced Consulting Partner, did a complete study of the client’s technology landscape and proposed a comprehensive app migration and modernization exercise.
The implementation objectives were focused on improving the performance of the existing application in terms of scalability and efficiency. The key goal was to increase agility to keep pace with changing business and consumer demands. By replacing multiple legacy applications, maintenance costs can be reduced. It was important to ensure that there was no downtime or disruption of services during the migration journey.
The best practices driven, automation-led implementation roadmap ensured
• Streamlined and straight-thru-processing and simplified technology infrastructure • Technical agility through faster application release cycle, Test Automation and reduction of platform complexity leading to reduced cost of changes • Development of new functionalities as modular services • Push Button Deployment with Blue Green model for minimal downtime • Technology refresh aligned with enterprise IT and data roadmap, leading to improved platform scalability • Containerization of Application and Technology Platform (App Server & App) using Docker • Infrastructure and application monitoring automated with AWS CloudWatch, Lambda and SNS services • CI/CD Automation for Seamless Build & Release Management through Jenkins.
We could successfully transition ~ 200 FTEs catering to the B2C, B2B and Finance functions spread across 2 countries (Sweden and The Netherlands).
Transition done in clusters (basis LOBs, similarity, complexity, etc.)
A Well-planned Transition Process
Initial Phase – Lower criticality, Later Phase – High criticality
Responsibilities split between the client’s retained organization and Hexaware
Proposed a to-be state operating model with an onshore and offshore component across in-scope processes
Tracking and reviewing the risks periodically with all the stakeholders until closure
Key factors of the split - language dependencies, regulatory requirements and end customer interaction requirements
