I think those two abilities which you cite are developed ONLY with experience in solving real-world work problems. These are not skills which can be taught in a school. They have to be learned through work, through mentorship and through the experience of failures and successes. Internships certainly help, but it takes years. It's OK if hires fresh out of school aren't able to do these things. These need to be cultivated by you, the manager.
