I have been working for my employer for 12 years and have been in my current department for 5 years. There is a management role in another department that I feel I could do much better than the current manager. I feel that customer service could be improved and I could incorporate my skill set to change the role but make it more productive. I have spoken to my manager, he has said that he agrees I would be a good person for the job and I need to "make some noise" to push for the job. How do I do this? I dont want to go down the route of pointing out every mistake that the manager makes, however, I need to show that I could do it better. Am I completely out of order for even thinking about this?
