In the first five minutes, do your credentials earn trust—or drain it? This lesson shows you how to speak with executive tone and script a three‑beat credentials slide—Authority, Relevance, Assurance—tailored for UK understatement and US directness. You’ll get clear frameworks, tight real‑world examples, and targeted exercises to sharpen phrasing, delivery, and agenda control. Finish able to open decisively, narrate credentials in 60–90 seconds, and pivot the room calmly into the work ahead.
