Question: On average, how many times per month does Windows crash or experience serious bugs?Question: Rate your overall satisfaction

Source: Microsoft January 2003 survey of 754 homes and 503 small businesses

Crash frequency highly correlated to customer satisfaction

As crashes increase, customer satisfaction decreases

“Rule of thumb:  A defect that costs $1 to fix on the programmer’s desktop costs $100 to fix once it is incorporated into a complete program and many thousands of dollars if it is identified only after the software has been deployed in the field.”
