The increasing focus on security and data protection, underscored by the fact that 91% of customers consider security a critical factor in their banking decisions, necessitates robust modernisation efforts to address these evolving concerns.
Recognising these drivers is essential for building a compelling case for modernisation.
A Step-by-Step Modernization Strategy
To effectively modernise legacy banking systems, follow this structured strategy:
- Conduct a System Assessment: Begin by evaluating current legacy systems to identify their strengths, weaknesses, and areas needing improvement. This assessment is crucial, as 55% of banks see their banking legacy systems as significant obstacles to achieving their digital goals. Understanding these strengths and weaknesses allows for the design of high-impact strategies tailored to specific business needs.
- Define Objectives: Establish clear goals for modernisation, such as enhancing client experience, improving security, or reducing operational costs. Before implementation, businesses must identify their specific needs, such as reducing response time, improving self-service options, or enhancing customer satisfaction. A well-defined objective is essential; 93% of decision-makers believe their company’s future success hinges on selecting the right core banking solution to replace outdated banking legacy systems. Tailoring these objectives to align with high-impact strategies can further enhance scalability and growth.
- Choose a Modernisation Approach: Decide on a modernisation strategy—whether to fully replace, re-platform, or integrate new technologies with existing systems—based on the assessment and defined objectives. Remarkably, merely 2% of surveyed financial institutions intend to remain with their traditional setups, signalling a significant industry transition towards modernisation. Antony Jenkins, CEO of 10x Banking, points out that restrictions in banking legacy systems impede the operations and transformation of financial institutions, stressing the necessity for a strategic approach tailored to the organisation’s specific objectives.
- Develop a Migration Plan: Create a detailed migration plan that outlines the timeline, resources, and budget required for the modernisation process. This plan should consider the parallel run approach, allowing old and new systems to operate simultaneously, which helps mitigate risks associated with full transitions. With 42% of financial institutions planning to replace parts of their banking legacy systems within the next year, this approach is increasingly relevant and should be tailored to the unique operational needs of each organisation.
- Implement Incrementally: Roll out changes in phases to minimise disruption and allow for adjustments based on feedback. This incremental method is essential, as 69% of financial institutions mention perceived risks linked to transitioning to newer technologies as an obstacle to implementing next-generation solutions. Tailoring the implementation phases to suit the particular operational environment of the financial institution can improve the effectiveness of this strategy.
- Monitor and Enhance: Continuously evaluate the performance of the new setups and make necessary adjustments to improve functionality and user experience. Regular monitoring ensures that financial institutions can adapt to evolving customer expectations and technological advancements. It is also essential to put in place strong security measures, as outdated infrastructures are susceptible to contemporary cyber threats, which can result in considerable financial and reputational harm. Tailoring the monitoring processes to align with high-impact strategies can further enhance operational efficiency.
This organised method not only enables efficient modernisation but also assists financial institutions in managing risks and ensuring service continuity during the transition.
Modernization Approaches and Patterns
In the quest for modernization, banks can adopt various strategies tailored to their unique needs, focusing on scalable and sustainable growth:
- Big Bang Approach: This method entails a complete overhaul of the legacy system in a single operation. While it guarantees swift change, it is filled with increased risks, including possible disruptions that can impact user experience and operational stability. Historical data indicates that big bang migrations often take at least two years to prepare, and the complexity involved can lead to significant project delays and failures, as noted in the report ‘Core Banking Transformation in 2024: Driving Innovation Through Cloud-native Core Banking Platforms’ by IDC/Thought Machine. However, with customised technical strategies, financial institutions can reduce these risks and enhance customer experience through improved response times.
- Phased Approach: This strategy concentrates on gradually substituting elements of the legacy framework over time. By implementing changes in stages, financial institutions can leverage real-time feedback to make necessary adjustments, significantly reducing the risk of operational disruption. This approach facilitates simultaneous testing and a more seamless transition, allowing financial institutions to begin migrating to new systems within months instead of years. For example, the staged migration process can assist financial institutions in attaining 100% migration precision prior to going live, as illustrated in the case study on phased core banking migration with SuperCore. This method not only facilitates scalability but also improves user experience by reducing service interruptions.
- Hybrid Approach: This merges aspects of both the big bang and phased strategies, enabling financial institutions to replace essential components while keeping some legacy systems until they are fully ready for transition. This flexibility can help mitigate risks associated with abrupt changes in banking legacy systems and ensure that user experience remains a priority throughout the modernization process.
Each approach offers its own benefits and drawbacks, and the best option will depend on the institution’s specific circumstances, including budget limitations, timelines, and risk tolerance. By thoroughly assessing these options and applying customised technical strategies, banks can identify the most effective modernization approach that aligns with their operational objectives and client expectations. As Steve Traut emphasises, ‘Whichever route you choose, customer experience should be prioritised at all times.
