> engineers report the most mixed results on quality later in the survey (51% better but 21% worse, the highest “worse” of any role).

Hardly surprising.

PMs, designers, and founders do work that has no immediate feedback on right/wrong, so anything plausible is good enough. Code that doesn't compile or pass the tests or doesn't do what it's supposed to fails the quality threshold immediately.

Self-selecting survey with no other visible methodology, and anything interesting is behind a paywal.
