Do your impact notes still hedge with “probably” and “some users,” leaving stakeholders to guess the downside? In this lesson, you’ll learn to articulate impact with authority by separating observable effects, blast radius, guardrails, and explicit fallback triggers—so risk is computable and recovery is inevitable. You’ll find a tight framework, real-world examples, and targeted exercises (MCQs, fill‑in‑the‑blanks, and error correction) to harden your language and reassure stakeholders. Expect surgical edits, measurable thresholds, and templates you can drop into PRDs, RFCs, and release briefs today.
