EXAMPLES OF DEFECT ANALYSIS at OTHER SITES | *The National Software Quality Experiment conducted by Don O'Neill Consulting, collects core samples of software product quality in the Software Inspection lab. Distributions of fault types disocvered during the software inspection activity are provided with different views:

*Orthogonal defect classification, or
ODC, from IBM, is a scheme
to capture the semantics of each software defect quickly. It is the definition and capture
of defect attributes that make mathematical analysis and modeling possible. Analysis of
ODC data provides a valuable diagnostics method for evaluating the various phases of the
software life cycle (design, development, test and service) and the maturity of the
product. Charts are presented of defect classes that have been discovered with triggers
(specific types of problems) used with various discovery activities throughout the
lifecycle.
