From the Ask Tom mailbag:

Question:

What happens when you realize you were given a promotion and not able to live up to the capabilities? Do you admit it to your superiors? Do you keep it to yourself and risk failure?

Response:

There are many ways to survive in a position that’s over your head, but in the end, it’s only survival. Not a way to live.

I often ask managers, “How do you know, what behavior do you observe when a person is in over their head? Where the Time Span required for the role is longer than the Time Span capability of the person?”

The descriptions come back.

• They feel overwhelmed.
• They cover things up.
• They cut off communication.
• Their projects are always late.
• I can’t ever find them.
• They always blame someone else.
• They have all the excuses.
• They never accept responsibility.

So, the short answer is yes. When you realize you are in over your head, go back to your boss. Explain the difficulties you are having. Ask for help. If it is a matter of capability (Time Span), no amount of training, no amount of hand holding will help. It is possible that you may grow into the position, but it’s more likely a matter of years, not weeks that allows for the required maturity (increase in Time Span).

This doesn’t make you a bad person, it just means you were placed in a position where you cannot be effective. Yet!
