I've been thinking about code reviews a lot.. and I think a big problem with existing code reviews is that for most orgs, code reviews were a way to move planning to the end of the development process instead of keeping it up-front.

I think the foundation of the pyramid (API and Implementation semantics) is often discussed in code reviews when it should have almost no place. By the time you get to the code review not only should these have been ironed out and shared with the whole team. What you should be looking at is simply adherence to the plan, and calling out deviations.

I wrote about a small rat about this: https://xangelo.ca/posts/code-reviews-are-failure/
