A computer method is disclosed for the estimation of the density of errors which may be introduced into an element of software during its development. Histograms of the error density versus the development phase have been found to have a shape resembling a Rayleigh curve. By inspection, the area underneath a curve, representing the error density versus development phase, will give the total number of expected errors over the life of product development. In accordance with the invention, the user can take actual measurements of the occurrence of errors during several phases of the development cycle for a software product. The user can then make a best fit of a Rayleigh curve to the measured data.
