Yet the things I do seem so obvious to me that I can’t help but wonder why they didn’t see that obvious solution I’ve implemented. Practically everyone who has a decent amount of experience delivering something feels that way. Usually it's a combination of the original team not having as much experience, or that the situation at the time didn't allow it (lack of resources, incompatible acceptance criteria that no longer apply, etc), or that you've missed something important that actually means the solution you're going for is the wrong approach. Understanding which it is is hard.
