INTEGRATINGNEXT-GENERATION COREBANKING PLATFORMS 10 key considerationsfor core system modernization INTRODUCTION Many banks today face mounting pressure to modernize their technological infrastructure,and some are approaching the end-of-life of their legacy core banking systems. The legacymonolithic core, once the backbone of financial services, is increasingly being viewed asbottlenecks. The demand for scalable, flexible, and cloud-native solutions has shifted theindustry’s attention towards next-generation coreplatforms. Next-gen cores have differing approaches to their solutions — some focus on customizabilityof the product, while others focus on ready-made building blocks that prioritizes speed-to-market.Allofthemenablebankstoembracecloud-nativearchitectures,prioritizeprogressive system modernization, and deploy innovative products at scale. Addressingcomplex requirements such as product innovation, regulatory compliance, cost reduction,and operational efficiency in banks necessitates a thoughtful and future-proof approach tocore system transformation. Core modernization is one of the most complex and high-risktransformations that our clients are facing at the moment. AtOliver Wyman, we have a team of seasoned experts who havehelped deliver and de-risk such core transformation programsglobally, and more recently in AsiaPacific. This paper brings to light the top considerations banks mustaddress to navigate modernization efforts effectively, blendinginsights from Oliver Wyman’s real-world experiences. Whether the goal is to adopt a modular composable core, balance regulatory burdens, orenhance digital customer centricity, these practical considerations will ensure a smooth andimpactful transformation. 10 KEY CONSIDERATIONS FOR CORE SYSTEM MODERNIZATION 1Program set up, governance,and risk management 6Migration strategyand execution Portfolio complexity and degree of hollow-outshould guide the decision on migration approach.A phased or co-existence approach is typicallyoptimal for most banks over a risky big-bangcutover. Derisk migration by leveraging an active/active configuration to mirror requests on bothnew and old cores until the new core isstable Setting up the right governance structuressuch as a Control Tower to introduce newways of working, leadership principles, andfacilitate cross-functional team alignment onkey topics such as hollowing out and migrationsequencing is key to de-risking overall delivery 7Operatingmodel refresh 2Business andcost strategy Gaining business stakeholder buy-in with clearbusiness justifications for transformationprogram, assessing cost holistically byfocusing on Total Cost of Ownership (TCO), andmanaging the value narrative to build trust inthe program is key given the capital-intensivenature of core modernization programs Adapting organizational structure andoperational workflows for the new platform,and linking business needs with technologycapabilities is key when designing the targetoperating model 8Peopleand talent Upskilling teams for new systems and processesand designing change management programsto bring stakeholders along the transformationjourney are crucial for long term success ofthe program. Workforce needs can also beaugmented with external system integrators(SIs) or partners to allow for more gradualramp-up in the organization Balancing system upgrades and transitionswith negligible impact on customer experienceto reach parity first, then looking longer termfor innovative experiences to differentiate thebank by leveraging the newstack 9Data managementand security 4Vendor selectionand contracting Ensuring vendor offerings align with futureproduct roadmap capability — and not just theminimum viable product — is key to buildingscalability across architecture, ensure vendorcost control in-line with platform consumption,and avoid contractual pitfalls Core modernization program offers anopportunity to sharpen data quality andintegrity, given the underlying changes indata model when migrating to a new platform.Executing this in a phased approach, with focuson encryption in transit and at rest are key tode-risking the overall migration 5Technology andsystem abstraction 10Observability andtesting protocols Technical dashboards can be built downstreamto track key performance metrics such as latency,utilization, errors, and idle capacity. This is key tomonitoring the new platform for resiliency andstability, and serve as a guide for when rollbacksshould happen Hollowing out as many capabilities before themigration and building a single abstractionlayer to facilitate abstraction, rather thanmaking point-to-point change requests to eachinterfacing system, can increase efficiency andreduce change management during the cutover PROGRAM SET UP, GOVERNANCE,AND RISK MANAGEMENT1 Core modernization is complex and introduces risks across business impact,operational, and security dimensions.
