Upskilling is a word I first came across when I worked in London in 2009 for a company that has since been acquired by Garner. It's a fancy way of conveying that you as a change manager teach other professionals a skill while implementing the transformation. Based on my experience, running aPMO (project management office) and navigating a business case are essential skills for anyone who works in change. At times, you have to empower others - even very seasoned professionals - to internalize them.
