The feedback you're not giving is the problem you keep having
You're frustrated with someone on your team. They're not meeting your expectations, they're not "getting it," and you can feel resentment building every time they miss the mark. You've been giving them direction, assigning tasks, course-correcting their work - and yet nothing changes. Before you conclude that this person isn't capable, it's worth asking a harder question: have you actually told them what the problem is?
