@[email protected] I've had the unfortunate experience of working in a team where the tech lead (who's priority on paper was managing, not coding) used this position to "get stuff done" by lobbing low quality work over the wall and relying on the teams under him to tidy it up, fix the bugs, add the tests, etc.
I found out via an irate bug report from a customer one Monday morning that he had released a whole new feature over the weekend without code review (because, well, no one else was online...), and I was now responsible for second line support on it.
@[email protected] He was called out by name in the next all hands as an example of the work ethic we should all aspire to, when in reality he was at best a minor driver in the team making any progress at all and frequently caused other team members to be late delivering things due to having to clean up after him.
