In my experience, people who have successful PMO careers have a broad skills base. They are generalists who have skills that bridge the gap between project and operations; finance and creative; orators and the industrious. But when it comes to the types of training PMO professionals seek out, it always seems to be depressingly narrow. The focus is on either qualifications in project frameworks, or on PMO certifications such as P3O [1].
Looking around, there are lots of courses that could not only help PMO professionals in terms of their personal development, but could help the organizations they work for too. I've pulled a few examples of training courses that will boost PMO professionals' careers [2] over at HotPMO.com [3], but I'm keen to hear your ideas too. Thoughts?
