I don't have much more experience as a manager than you do but here are some thoughts. 1. Share the roadmap with your team once confirmed by management 2. Don't force your implementation on the team but let them come up with it and use it as long as it is good enough 3. The time will never come that you feel that your reports are ready for hand over - it will only come by necessity when you are asked to take on more responsibilities so that you have no choice but to hand off this work. So, you may as well start the hand over today as there will never be a better time.
