Claim: Schulmeyer formalized the "Net Negative Producing Programmer" concept in 1992 — programmers whose defect rates are high enough that the cost of their errors exceeds the value of their output. In a typical team of ten, he estimated up to three may qualify.
BLUF: 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.
Probability: Likely (55-80%) | Confidence: Medium
Correction needed: The original publication may be 1987 (Handbook of Software Quality Assurance) rather than 1992 (Total Quality Management for Software).
