People tend to forget that managing people is a job in itself. The number of times you see people promoted to a “manager” with the expectation that they will do that and continue at the same level of IC output is ridiculous.

Give them problems along with the constraints and how success will be measured. Then monitor progress and correct as needed. This will mean that you have less time to do the work you were originally doing.
