Why banks are likely to face more software glitches in 2013
The core of the problem is that the business software used by the institutions has become horrifically complex, according to Lev Lesokhin, strategy chief at New York-based software analysis firm Cast.
He says developers are good at building new functions, but bad at ensuring nothing goes wrong when the new software is added to the existing mix.
"Modern computer systems are so complicated you would need to perform more tests than there are stars in the sky to be 100% sure there were no problems in the system," he explains.
"Business software is becoming increasingly complex, composed of sub-systems written in different programming languages, on different machines by disparate teams.
"This means no single person, or even group of people, can ever fully understand the structure under the key business transactions in an enterprise. Testing alone is no longer a viable option to ensure dependable systems."
Mr Lesokhin adds the West's banking system is particularly exposed because it was the first to install computer systems and much of the sector was badly wounded by the credit crunch's knock-on effects.
Decades of bolt-on code has made banking systems complicated to comprehend. "Tough financial times mean a squeeze on budgets and less effort spent on modernisation and quality assurance," he says.
