Comparing four case studies on Bohr-Mandel characteristics using ODC

This paper uses four case studies to examine the difference in properties of Bohr-Mandel bugs. The mechanism used to differentiate Bohr versus Mandel bugs are the ODC Triggers that was developed in a previous study on this subject. In this study, the method is extended to reflect on two additional dimensions. First, on the customer perceived impact. And, second, on how these change between their manifestation in production or the field usage versus late stage development or quality assurance testing. This paper: ; Compares Bohr and Mandel bugs rates between customer/field usage and pre-release system testing. ; Finds that Mandel bugs predominantly have a Reliability-Availability-Serviceability (RAS) Impact. ; Finds that Mandel bugs, rarely, if ever have a Functional Impact. ; Finds these studies predict Mandel bug rates consistent with other studies. ; Finds that pre-release testing found very few Mandel bugs (<;10%).
