I have a hard time imagining that most code reviews take &lt; 10 minutes.<p>* Understanding of the problem at hand, reading through the story, understanding the context of the the code change.<p>* Pulling down the code, reading through the commit log<p>* Reading the specs, possibly running coverage tools if not part of testing suite.<p>* Understanding the logic of the code, seeing if the tests cover the edge cases<p>* If dependencies change, they may need to be investigated too<p>* Thinking if there are better ways make code a bit more extensible or understandable<p>* Thinking of risk of the code (security, performance, deployment concerns)<p>* Reading through associated documentation and ensuring its accuracy<p>Doing all of this takes me longer then 10 minutes always.
