Becoming a new manager is a learning process. It wouldn’t be expected for them to know or handle everything from the get go. To help them ease into their new position, start the manager out with a fair load of responsibility and duties. Monitor how they handle themselves and if they make progress. As they grow and learn, gauge how they would handle new or different responsibilities. Sometimes adding a new project or assignment gradually can help them have hands on learning while gaining new responsibilities. With anything new, moderation is a key. Don’t overload the manager too quickly or they could lose interest and fail to succeed in their position.
