This lesson gives you a reliable C‑A‑D‑S framework to deliver clear, scope‑safe answers that distinguish on technical grounds without inviting narrowing admissions. You’ll get concise explanations, model formulations, and a bank of phrases—plus targeted examples and exercises—to practice structural, functional, performance, process, constraint, and data‑driven distinctions. Finish able to craft a 45–90 second response that anchors to the claims, signals non‑obviousness, and preserves strategic breadth.
