Customers of Commonwealth Bank will start to find that products are better tailored to their individual requirements and that pricing is more likely to be based on their relationship with the bank and their risk profile.CBA chief executive Ian Narev said the bank was just starting to get "creative" with its A$1.1 billion core banking upgrade. After four years, this project is nearing completion. Narev, who was speaking at the Trans-Tasman Business Circle yesterday, said: "The technology is ahead of the people. Now we need to bring the people and the creativity up to the technology. That is my job."Over the past year, the bank has promoted innovative mobile banking applications, such as Kaching, which allows customers to make payments to Facebook addresses and to mobile phone numbers. Narev said banking was becoming a "companion activity" - something people did while they were doing something else.Fifty-three per cent of log-ons to the bank's online banking service, NetBank, are via mobile devices. That number is up from 19 per cent a year ago.Important as convenience is, it is not the only thing the core banking upgrade has delivered.The bank used to take months to change a product. Narev said the new system allowed the bank to break products into their components."Product response is going from weeks to hours," he said."Products will be tailored to individual customer requirements and when we are pricing we will be able to look at the customer's relationship with the bank and their risk profile."The bank has also made much of its ability to process transactions and update accounts in real time. Narev said this was becoming the benchmark for customers."Our system makes sure that what the customer wants to do occurs when they do it."Narev said that when he looked at the competitive environment he looked at what companies like Google and Apple were doing, as well as his big bank peers. He said the big differentiator from "technology-driven attacker models" was the trust the bank had with its customers through its capital and liquidity.
