From the forthcoming updated edition of my book:
Take an assembly line, stamping out 10,000 widgets an hour. Predictable, measurable, a suitable subject for process control techniques such as Six Sigma.
Much ink has been spilled in the software engineering literature, emphasizing that writing software cannot be reduced to such determinism. It’s not clear who was assuming it could be so reduced, however – overzealous, uninformed process analysts, perhaps, or project managers craving certainty. Perhaps the early initiators of CMM.
One thing is likely, no person with knowledge of manufacturing would have said this. Nor would have Alan Turing.
