A proven methodology to achieve shorter time-to-market and produce higher quality software at lower cost

It is critical to use the correct software defect model

The traditional software model assumes that defects are uniformly distributed:

The following model, where defects are clustered, is more consistent with experience:

UniformBugs

Practical experience and common sense do not substantiate the traditional model.

This is why we have enunciated Levendel’s Axiom:

Bugs Abhor Loneliness CIMICES ABHORRENT SOLITVDINEM

The concentrations of bugs create software “black holes”

In fact, this observation is the key to cost savings and quality gains, since software black holes (concentrations of bugs) are easier to locate than uniformly distributed isolated defects, and eliminating them will dramatically improve software quality. As a result of this improvement, software variability will be progressively reduced.
