And Here's a Number You Can Take to the Bank!!

In reference to the article on unit testing, here is an interesting excerpt from the following article written by one of my former colleagues Paul Julius:

‘ The reason I was there was simple. Earlier that year, those same IT managers had performed a series of calculations to estimate how much it cost the department each time a bug made its way out of development, into SIT, into User Acceptance Testing, or all the way into production. For this IT shop, one bug into SIT cost them $12,605 (and you can imagine how much a bug into production would cost.) So, I did some quick math. The burn rate for the developer who introduced the bug was $70 per hour. Since the developer had already fixed the bug and committed the change, I deducted the $70 from the total and ended up with $12,535. Now, it cost them $70 (or less) to fix that one bug, instead of $12,605.’

So I’ll ask you again. Would you rather spend $12000 to fix a bug or $70?
