You just finished building your company's website. You have tested it yourself and had other company employees test it. The website now goes live. A few weeks later you start getting emails from irate customers who complain that they are unable to place their orders because certain steps in the “Buy Now” process give errors. You quickly fix the problem. A few days later you get complaints about some other issue and you again react quickly to fix the website. This continues for a few months till the complaints finally halt and things stabilize.

At this point you make some enhancements to your website. A few days later a customer email alerts you to the fact that in the process of making this enhancement you “broke” something else on the website. Again you spend time to find and fix the problem but by now you are perplexed and not a little frustrated. These issues have cost you many customers in the last few months and potentially spread ill will across the broader customer community. It seems to you that the only way to have detected these issues before they went “live” was to have employed a large army of software testers, something your company is unable to afford.
