Tired of buyers rejecting “without undue delay” as too vague? In this lesson, you’ll learn to craft breach-notification timeline wording that is precise, auditable, and aligned to law and contract—so procurement and legal say yes on first read. You’ll get a clear framework (trigger, time unit, outer limit, channel, content, updates, authority alignment), real-world templates and examples, and targeted exercises to test and refine your language. Finish with a compliance checklist that eliminates ambiguity, reduces redlines, and accelerates time-to-contract.
