I wrote the Great Talk Africa workbook from inside the exact transition you're navigating, not from a theory I read somewhere. I climbed from executive assistant to Executive Partner to Chief of Staff myself, and I'm still doing this work today: as Chief of Staff at Pioneer Outsourcing BPO, and as fractional Chief of Staff to Epena Law, a pan-African corporate law firm, alongside past work as Country Lead and Executive Partner to the Global CPO at a fintech company in Stockholm. I know what it feels like to get a new title and still be doing the same job for months, because nobody told me the job itself was supposed to change. I also now sit on the other side of that gap, as the person organizations bring in to actually close it, which is what the section for leaders is about.
One thing worth saying plainly. Becoming a Chief of Staff is not a promotion in the way people usually mean that word, and staying an EA is not settling. They're different roles built on different skills, and there are excellent, well paid, deeply respected careers in both. The workbook and mentorship are for the people who read Module 1 and feel a genuine pull toward the CoS side.
