I may be completely wrong but to me this has played out and will play out like this: 1. First engineer is motivated an has great qualitative and quantitative output. 2. First engineer's opinion is being ignored when second engineer is being hired. Can't be good for motivation. 3. First engineer has to fix the work of second engineer. Qualitative and quantitative output suffers. Motivation of the first engineer decreases further. 4. Warnings to the management are being ignored. First engineer gets so frustrated that he quits. 5. Second Engineer has now free reign. Even if quantitative output is still the same, the quality totally tanks. I don't recommend that the first engineer quits because that would be a pretty big decision to make without trying to fix the situation first. But if management makes such a severe error in this early stage of the startup, there may be some more "interesting times" ahead.
