Very good piece in today’s “The Sheet” about the upcoming replacement of CBA’s core banking system. Correctly, it is entitled “Adventures with core systems: part I”. The belief that most banks in Australia need to replace their core systems reasonably soon is a strong one – and in most cases justified. The problem, of course, is also well known.
Core system replacement is expensive, risky and time-consuming. It is a huge change management task, with most of the bank’s staff well trained on the old one. For example – I dropped into my bank to close an account a few days ago. Sitting down with my “client adviser” she opened a web browser to check on my balances and see what I wanted to do. To do the bit she would need to show me she left it in the browser. However, as soon as she wanted to actually do anything she opened up a terminal emulator. I peered around and asked why she had not done it in the browser.
Her response was simple – the browser allowed her to do it but she was much faster on the terminal. Essentially, although the terminal emulator was lousy to look at it was effective and fast.
At that bank, and almost every one I have ever been into the story is the same – bank staff are comfortable with the old systems. Despite the fact they are built on technology that was outdated 20 years ago they still work. Staff are familiar with them. Anyone seeking to replace the system not only has to make it work from a technological viewpoint – but it also has to work in the organisation.
In comments, feel free to add in your favourite banking core system replacement story. Ones from Westpac are particularly invited – the one that was particularly successful a few years ago sounds good. Operational risk events can also be pretty funny – if you are not in the middle of one.
