“Big Bang” Bank Upgrades Spell Trouble, Mambu Makes Case for Incremental Change

“Big Bang” Bank Upgrades Spell Trouble, Mambu Makes Case for Incremental Change

by March 14, 2024

Core banking systems serve as the backbone of financial operations and customer interactions for banks worldwide. They facilitate critical transactions like loan management, withdrawals, and deposits in real-time.

However, maintaining such a system comes at a hefty cost. Financial institutions (FIs) are spending up to US$100 billion annually on technology to remain competitive. Modern all-in-one platforms offer efficiency improvements, scalability, comprehensive data analytics, robust security measures, and cost savings.

The necessity for digital transformation

The COVID-19 pandemic and increased competition have accelerated digital transformation in Asia-Pacific FIs. Customers increasingly rely on digital channels, prompting banks to allocate more resources to technology budgets.

However, simply maintaining legacy systems is no longer sufficient. Older IT stacks represent significant technical debt, hindering innovation, uptime, and meeting market needs.

Investments in technology drive digital maturity, product agility, data-driven personalisation, and enhance the financial experience.

Despite having clear digital strategies, over 80% of APAC banks have yet to achieve their digitalisation goals. The emergence of digital-native banks and fintech firms poses a significant threat to traditional incumbent banks.

The problems of a ‘Big Bang’ approach

A ‘big bang’ legacy replacement can promise a swift solution to outdated core banking systems’ problems. However, this approach often brings about more problems than benefits.

The scale and complexity of replacing an entire legacy system can overwhelm resources and lead to prolonged implementation timelines and substantial cost overruns.

Additionally, the risk of operational disruptions during the transition period is significantly higher.

Consider incremental changes

Incremental change using dual and parallel core platforms is suggested as a strategy with less risk and lower cost compared to a ‘big bang’ approach.

Dual core platforms involve progressively migrating customers based on key lifecycle events, while parallel core platforms entail launching new customer propositions and experiences and then migrating existing customers.

Incremental transformations take months to complete, without disruption to critical systems.
