Businesses and IT failures
As use of IT in businesses grows, so too do events of system crashes and failures.
It is a problem not confined to banks, where system crashes and botched upgrades seemed to be a regular feature of existence for many customers.
System problems bedevil many industries, according to an article by The Economist recently.
It says: “software is hard—and hard to keep up with”.
A very small error in the writing of a line of code can have a huge impact on a whole system, it says.
It quotes from a book, “The Problem With Software: Why Smart Engineers Write Bad Code”.by Adam Barr, who argues that too many software engineers and programmers are at last partially self-taught, leading to the development of what he calls bad habits.
Another problem is the relentless pace of change in IT, leading to systems rapidly becoming obsolete.
This applies equally to the developing ingenuity and skills of hackers, who develop ever more inventive ways of invading systems that then require patches or additional safety measures to protect their users.
Fixing bugs in an old system, however, can never be as effective as building a new one from scratch, and how many businesses can afford to do that regularly?
