This may be going off topic, but I've been thinking about engineering gaffes getting into production. I once took a job with a company who had just fired its senior engineer. The second in command had resigned, leaving only a PCB designer in the department. I worked overtime to finish the electrical design of a new product, which happened to use a number of transistor array chips, and handed it off to the PCB designer, who did a terrific-looking job with the artwork. The boards were rushed into production, but the production test guys couldn't make any of them work. After several days of struggle, they finally asked me for help. It turned out that the PCB designer had swapped transistors in some of the array chips. Now if you're not familiar with these devices, understand that the transistors are matched and interchangeable except for a single detail: One of the transistors has a leg tied to the substrate. If it's an NPN array with one of the emitters tied to the substrate, for instance, then this emitter lead must be at the most negative potential in the device to avoid current flowing through the substrate to other transistors.
After initially blaming myself for this fiasco, I realized there's a more nuanced explanation: company culture. The PCB designer had no authority to alter anything in the schematic drawing, but he was unwilling to request an engineering decision because the previous engineer had been an autocratic bully. In addition, the PCB guy was working around the clock because top management was desperate to have the product for an imminent trade show. The production test technicians were busting their butts for similar reasons, which only delayed the resolution.
I haven't got a whisper of a clue about the culture at Scott when the 200 was designed, but my little story might suggest an explanation for the wrong resistor value we discovered. This stuff really happens, even at NASA.
