Data & AI Month advocates the use of data analytics within NAB to make better decisions, hyper-personalization, and meaningful insights in banking and customer experiences.
During its Data & AI Month, National Australia Bank (NAB) is bringing teams together to reconsider the way they are using data, prioritizing problem solving instead of reporting. According to Christian Nelissen, NAB Chief Data & Analytics Officer, it is now evident that data analytics has become core to the development of business, risk management and customer experience.
Nelissen presented some cases of how the exploratory application of data analytics brought about better customer services, efficient banking experiences, and more intelligent work solutions. He said, “It is a business of asking tougher questions and a business of data and finding real opportunities as opposed to dashboards.”
The Customer Brain is an intelligence engine empowered by the bank's central data lake allowing the teams to translate insights into useful actions at a low velocity rate. Nelissen stressed that forced data reliance remains a secret to the emergent technologies such as GenAI where knowledge becomes accurate and defensible.
Ari Kaplan, Global Head of Evangelism at Databricks, shared at the session how the Moneyball philosophy is changing customer engagement by hyper-personalizing insights to act on behavior. Jo Gurry, NAB Executive of Data Platforms, further added that data analytics is more than intriguing information, but that it is something that can be acted upon.
Data &AI Month with more than 40 events involves employees in different roles and provides an opportunity to collaborate, be curious, and be innovative. NAB has plans to integrate data analytics into all corporate decisions and convert insights into practice and also instill a culture where data becomes the enabler of smarter solutions for customers.
