Act as a professional communications coach. I need to email my department head about a project that's 2 weeks behind schedule due to a vendor delay — the relationship is good but she values directness. Please draft a concise email that acknowledges the delay, explains the cause without blame-shifting, and proposes a revised timeline with mitigation steps.

The AEP framework is a starting point, not a rigid formula. As you develop your prompting skills, you'll learn when to emphasise certain components, when to add constraints, and when a simple prompt is all you need. The key insight is that AI performs dramatically better when it knows who to be, what it's working with, and exactly what you want.
