A great engineer isn't the one writing the most "brilliant" code; it's the one who understands the problem, picks the simplest solution that works, and makes life easier for the next person who touches it.
Which is why I have learned to stay away from people who use that metric.
In 3-4 years when you need to make a drastic change, that’s when the actual business impact comes into play, but this is never measured.
In my experience with some groups, waiting another 2-3 months to do things correctly would have saved years in future work.
