This is a technical talk on the Bohr-Mandel bug theory, with experimental data that is compared to the results published by the NASA study on this topic.

- We discuss the Bohr-Mandel theory of bugs and argue that a greater insight and differentiation is possible through the use of ODC Triggers. In some respects, since the current definitions do not leverage the concept of triggers, there is confusion as to what they are.
- We conduct a case study to measure the proportion of Bohr-Mandel bugs using ODC Triggers.
- Our case study results are compared to the JPL-NASA study on Bohr-Mandel bugs.
- Our estimates of Mandelbug proportions ranges (~20-40% range) are very comparable to those found in the JPL-NASA study.
- We find that the Mandelbug presence is uniform across multiple impact groups and components of the product.
- We found that in our case study, as the product ages in the field, the proportion of Mandel bugs seemed to drop. While this finding cannot be generalized, it does alert us to watch this phenomenon in other case studies. However, given the numbers it is clear that methods to alleviate the impact of Mandelbugs early in the lifetime of a product will be of significant value.
