This quote comes from Baseline Magazine (via /.):
Parasoft's own developers follow a strict routine and are required to turn in their code for testing every night by 7. Kolawa says he eliminated Quality Assurance (QA) testing?which traditionally occurs after software is developed?years ago, because code would bounce between developers and testers and no one would take responsibility for problems. "Eliminating QA worked marvels," he says. "It enforces a culture of ownership. It enforces discipline."
