To delegate effectively to a new team, you have to explain the following:
- Context and goal
- Expected results
- What to do
- How to do it
As the team grows and they learn how to do the work, it become sufficient and appropriate to explain only the first three bullet points. As the team further progresses, you can communicate the first 2 bullet points and the team will figure out what to do and how to do it. Finally, with high performing teams/individuals, you can provide context and the goal, and the team defines the rest.
Sharing the context and the goal is always necessary.
