Dr. Michaela Greiler is focused on helping teams make code reviews their superpower!
During Dr. Michaela's time at Microsoft, they found that developers were spending six hours a week doing code reviews. You have to ask yourself if that time is really being well spent.
How do you ensure that code reviews are worth the time? There is a huge variety of experiences with code review. It can be really good, and it can be really, really horrible as well. There is not a lot of formal training around it.
Formal training would improve the consistency and value of code reviews, and it would be especially helpful for Junior Developers. It would give them such a self-esteem and confidence boost if they would know, "This is what we're actually looking for, this is how we give code review feedback"
