I built a hacked up experimentation framework for clientside flags, that boosted my teams speed and confidence quite a bit. Hacked up because it didnt use existing serverside mechanism for a bunch of reasons.

Used the same experimentation framework for automated javascript binary releases, so at some point i could release 5 times a week, with no issues. Now i left the team, people took that on and continuing like tic toc.

Showed them how to use powerdrill (data drilling, analysis tool), and taught them metrics. It is surpising how little people care what their work is really about eventually, and bringing them data driven mindset gave even more productivity boost.
