Beth, it is important to have useful criticism. At General Electric we were schooled constantly about this. If you were going to criticize something you had better have an alternative. Quite frankly, the alternative may be argued with, but in the process we typically came up with a synthesis that moved things forward. Don't be afraid to criticize, but don't just complain, either.

Groupthink is also often a result of an ingrained organizational culture which unfortunately, transcends any one engineer's ability to break down and fix.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
