In the fall of 2001, I delivered staff training at the Privy Council Office in Ottawa — the senior public-service department that supports the Prime Minister and Cabinet. Two threads of teaching ran through the engagement: PowerPoint as software, and in-person presentation skills as a separate craft.

Two disciplines, one engagement

The software side covered the practical mechanics — slide structure, visual hierarchy, the difference between a deck that reads from across a boardroom and a deck that doesn’t. The presentation-skills side was older work: how to open, how to handle a room of senior listeners, how to use a slide instead of being used by it.

Federal public-service audiences are a particular kind of teaching room. They are precise about language, careful with time, and respectful of expertise that earns its respect. The work asked a lot but it gave back the same.
