Microsoft's Bug/Fix Success Rate:
Measuring the Toll of Windows 95

Last year, BugNet noted that Microsoft's industry leading bug/fix success rate slipped dramatically under the strain of getting Windows 95 out the door. During the three months prior to Windows 95's August 1995 release, Microsoft's success rate fell to an abysmal 55%. But what has happened since that glorious day? Let's just say Microsoft is back. As this chart shows, Microsoft's success rate in the year since Windows 95, has scored a bofo 88%. This rate is more than 20% better than the company's score for the prior year. And in the most recent month, Microsoft scored a 90% bug/fix success rate.
