Schulmeyer did formalize the NNPP concept and estimated up to three out of ten may qualify. However, the concept appeared in the 1987 Handbook of Software Quality Assurance, not 1992. The 1992 reference is to Total Quality Management for Software, a later edition.

Extract¶
Schulmeyer states: In a team of ten, expect as many as three people to have a defect rate high enough to make them NNPPs. The probability that there is not even one NNPP out of ten is virtually nil. The concept appeared in the Handbook of Software Quality Assurance (1987) and Total Quality Management for Software (1992).
