Unisys Heritage Simplification

[Audio] Hello Everyone, very warm welcome ! Today we will be presenting the success story of the Unisys Heritage Simplification Program..

[Audio] Let us dive into Customer and portfolio overview..

[Audio] NBS is the world largest building society with approximately 800 branches operating in the UK. NBS business portfolio is spread across Current Accounts, Savings Accounts, Mortgage and Credit Cards. TCS is engaged with NBS since 2010. TCS provide services to NBS in Application Support, Application Development, Infrastructure Engineering areas. TCS provides its services from UK and 3 Sites from India namely Gurgaon, Bangaluru and Noida. Technology stack supported by TCS includes Unisys Mainframe, Fujitsu Mainframe, Link, dot Net, Pega Robotics and Pega BPM..

[Audio] Now let's talk about some of the challenges we faced during our journey..

[Audio] NBS Savings Account data is maintained on Unisys Platform. Critical processes such as Payments, Reconciliations and maintenance of Cards also runs on Unisys. Unisys is a legacy system. It is difficult to maintain Unisys due to challenges such as Limitation around design futureproofing, niche technology, lack of resilience, performance inefficiency & Capacity issues, Higher Maintenance cost, lack of documentation of existing processes. This is impacting the NBS business in terms of Customer dissatisfaction leading to customer dropout, Inability for future readiness, Compliance issues, High operational cost, Service delay, data inconsistency, delayed customer communication and High technical debt. Unisys Heritage Simplification program is to replace Unisys with modern platforms and migrate the Unisys hosted processes to these new modern platforms. Currently, UHS is the most critical program in NBS..

[Audio] NBS has already migrated the current accounts to SAP and baselined the migration process. NBS endeavors to migrate the Savings accounts to SAP. There are existing challenges with baselined solutions. There is dependency across SAP and Unisys platforms to run critical processes such as Reconciliation, Customer Communication and Payments. Unisys products need to be aligned with the SAP products to simplify the migration. Legacy accounts could not be supported by SAP and automated solution is required to close the accounts on Unisys and move the account data to more tactical platform. There has been data issues which resulted in incorrect interest and tax calculation on SAP. No documentation is available to understand the existing functionalities to be transitioned to the new platform. There is operational inefficiency around the baselined migration process in terms of longer migration window and migration can only be run on weekends..

[Audio] We did produce solution with help of team..

[Audio] TCS proactively engaged with UHS team and started brainstorming sessions to address the challenges. TCS has developed the contextual knowledge of Unisys process over the time and helped in redesigning the migration process. TCS provided valuable inputs to make the migration event more efficient in terms of Flexibility to run on weekdays with smaller migration window. TCS did the reverse engineering to understand the existing functionality on Unisys so that the new platform can be customized such that it can support the Savings Accounts. TCS opted for Agile based continuous delivery model so that parallel development can be done on SAP and Unisys. TCS designed new processes on Unisys so that reconciliation and accounting can be moved to modern platform and existing processes on Unisys can be decommissioned gradually..

[Audio] Some of the Solution Highlights are.. Solution Highlights.

[Audio] I think it is detailed enough and can just be articulated..

[Audio] And now The improvements we have are.. Improvement Drivers.

[Audio] Through brainstorming areas of improvement were identified. It was identified that migration event must be automated as much possible to reduce the manual intervention. Reusable utilities must be created for data correction. Scheduling of migration event must be redesigned to improve efficiency. New reports must be created to help users reconcile migrated accounts data from Unisys to SAP. Data cleansing must be performed on Unisys before migration so that accounts are not rejected during migration due to data issues..

[Audio] Next is what we delivered as improvements..

[Audio] Improvements were incorporated into existing migration process and other Unisys processes to simplify the decommissioning of Unisys and improve customer satisfaction. Product Design architecture for Unisys based products was simplified by doing the reverse engineering and understanding the complex code base. Dependency across SAP and Unisys was reduced resulting in reduced risk around hybrid banking. Various Automation Utilities and best practices were introduced to reduce the manual intervention and improving efficiency of migration process. Operation efficiency of the new migration process improved by approximately 70 %. Utility was developed to perform the data fix for 1.2 million customers to correct interest and tax. Migration window was reduced from approximately 6 hours to approximately 2 hours which resulted in better customer experience..

[Audio] Coming to this point we are happy to share some of the customer appreciations..

[Audio] Building on that we have received awards and appreciation at COO level and have been recognized for this effort. Thanks to all team members involved. Cheers..
