I am a health care CIO and a seasoned PMP and there are several aspects of your post that concern me. The first a general attitude that you know better than everyone else. I'm not saying I'm the best leader or even a good one, but I expect my managers to have some humility with their employees and I do my best to maintain that as well. IMHO, humility is the beginning of respect and the beginning of great leadership. Many of the best decisions I have ever made have come from ideas generated by my management team. How will you ever even know about those ideas if you already know more than they do? A leader's job is not to know everything, but to know all of the options and to choose the best one. Your employees will never feel comfortable bringing forth ideas with the kind of attitude that permeates your post.
The other thing that concerns me is that you seem to think management/leadership is the same thing as PM. As a PMP, I definitely recognize how PM can develop and sharpen leadership skills but they are no where near the same thing. When managing a project, you are aligning resources to accomplish specific tasks to complete a specific project. A good project manager will inspire the team to work cohesively and productively. I have seen very few good project managers. Managing a team that is juggling many tasks every single day is very different. You are responsible for their success, for their morale and engagement. It is no longer checking off tasks on a to do list like what you have experienced in PM. The few paragraphs I see above give me doubt that you have the attitude and interpersonal skills to develop the necessary relationships with employees to motivate them to perform at their best.
Lastly, your current skills, while still valuable, diminish in value when you switch over to management. That is because you should be spending much less time performing the actual work, and more time managing your team and collaborating with other management. I started out as a software developer spending 90% or more of my time writing code. The day I moved over into management, that dropped to almost zero. My software development skills went from being my strongest asset to one of my weakest overnight. Low performing managers have a difficult time with this and try to hang onto work they have no business doing.
I know this post is harsh. However, if you are serious about moving over to management, then you need to hear these harsh realities. I hope you can incorporate this feedback into your strategy. I wish you the best.
