DIGITAL BANKING
Q. WHY IS LAYERING MODERN TECH ON TOP OF EXISTING SYSTEMS A BETTER STRATEGY THAN A FULL CORE REPLACEMENT?
» If real-time banking is an operating model and an almost cultural transformation, then the challenge becomes how to get there without breaking what already works.
Full core replacements rarely deliver at the speed or certainty banks need. They are complex, high-risk, multi-year programmes that often delay the creation of value for years.
A layered approach is more aligned with how real transformation actually happens. You leave core systems in place while data, orchestration and decisioning layers are introduced on top.
This allows banks to activate realtime capabilities across functions such as product development, pricing, onboarding and servicing, without waiting for a complete rebuild. It also makes time to value much shorter and less risky.
I often describe this as“ keyhole surgery”. It’ s targeted, faster and delivers measurable outcomes early, which builds confidence and momentum.
If the goal is to operate in real time, then the transformation itself has to move in real time.
