Mark --
Even though I marked an excellent reply from Paul Mather as the answer to your question, allow me to add one more skill that I think is absolutely essential for a Project Online application administrator. That skill is being able to understand a client's requirements, and then translating those requirements into the setup of Project Online to meet those requirements. For example, suppose that your client tells you that some projects require work to be done specifically on a weekend. How do you translate this project management need into something you set up or create in Project Online? HINT: The correct answer is that you need to create a custom enterprise Base Calendar that schedules work only on a Saturday and/or a Sunday. This custom enterprise calendar can the be used by your organization's PMs as a Task Calendar on tasks that specifically require weekend-only work.
As an app admin for Project Online, your technical knowledge of the tool will not be enough to get the job done, but it will certainly help. The additional knowledge you need is understanding how project managers actually plan and manage their projects using Microsoft Project. If you can combine these two sets of skills together, you will be a much more effective application administrator for Project Online. Hope this additional information helps.
