This is really interesting and I think a fundamental difference between engineering and law (my profession).

In the legal sphere the incentive is basically to act like everything is perfect at all times. Technically according to the law you can be sued if you had a wheelchair ramp work 364 days a year but be closed on one.

You can be sued for clearing 99pct of the ice from your driveway if someone slips on the 1pct. If you'd cleaned 99 pct of the driveway as a lawyer you would announce: we cleaned the driveway!

The engineer might opine about how she failed to get the last 1pct and why. The lawyer would tell her to be quiet because she risks being sued.

To my mind the engineering model is better. I don't like the legal model. But it is what exists, and I guess this is why we tell engineers to delete their Slack logs every couple of years.
