It's practically cliche at this point to point out that new managers don't get enough training in the art of management, but I haven't seen a lot delineating exactly what topics new managers should be trained in.
Here's what I have on my outline for training new managers:
1. What exactly is a manager responsible for? I posted a list of manager responsibilities here recently.
2. Oversight: How to determine the appropriate amount and how to exercise it. Some employees need more interaction and oversight than others, and it's the manager’s job to determine how much is appropriate for each employee. What systems will the manager use for checking in and staying apprised of her employees' projects?
3. Feedback: the importance of giving regular feedback, making sure that employees know what they do well and where they need to improve. Withholding criticism out of fear of hurting an employee’s feelings does that employee a disservice, and that if a manager has complaints or concerns about an employee and the employee doesn’t know it, the problem lies more with the manager than with the employee. (And similarly, if you have an employee who rocks your world and the employee doesn't know that, something is wrong.)
4. Morale: the importance of looking out for staffers' morale and quality of life.
5. Public image: how to make sure employees are maintaining the organization's public image.
6. Employee policies: managers need to be familiar with all employee policies and understand that applying them inconsistently could create legal consequences. I scare them about these legal consequences.
7. Working with other department: how to work most effectively with other departments and the need to act in a gatekeeper role when other departments send work your way. How should the manager handle conflicting priorities?
8. Determining when to escalate things up the ladder and when the manager is authorized to act on her own.
9. Staff performance problems: what's expected of managers when a staffer is struggling, tools available to a manager in such situations, and how to be clear, direct, and specific about the standards of a job.
That's the basic outline that I use at the outset. Then I try to mentor new managers, so as challenging situations come up, I can hopefully help them navigate them.
What's on your own list for training managers? Or what do you wish someone had trained your manager in?
