How hard should engineers work?
bkbleikamp: Don't micromanage the developers.  Work with them to set goals, get explanation when goals aren't met, and celebrate when they are.In my experience, developers actually work way more than the 30-40 hours a week they're "in the office" - they are thinking about the problems they're trying to solve when they're at home or when they're laying in bed, etc.  You can't think of it as a clocking in / clocking out type of job.
