|It is a good thing for employees to ask questions before proceeding on a project, but it is still possible to have too much of a good thing. A great deal depends on the content and frequency of your questions.|
If your assignments are changing and new issues develop that truly raise key questions that you cannot answer on your own, then it is altogether appropriate for you to approach your manager with them. In this scenario, try to pick a time that is convenient for him, and make sure that your questions are focused, organized, and prioritized. It is also important for your manager to understand that you will be able to do excellent work by having these questions answered.
At the same time, try to honestly determine if you are asking the same questions repeatedly or if you could be answering your own questions by doing some homework. In this is the case, try to see if the questions you have been asking fall into a particular pattern or subject area. You may able to identify some areas in which you could profit from some additional training. In fact, you should even ask your manager for his thoughts as to areas in which you could use further training. However, if he gets upset when you ask this question, then there are some real questions about him.
