Gantt Chart

Outcome: Use Gantt Chart to make a focused product decision backed by evidence. User context: A data-center move maps delivery, network setup, rehearsal, freeze, and cutover. A supplier delay reveals affected dates. Product concept to apply: Gantt Chart. Why it fits: Use it for deadline work with real dependencies across teams or vendors. Do not use it when: Avoid false precision in discovery work. Maintain baselines and dependencies instead of drawing a decorative timeline. Product framing: Name the target user and wanted result. Record the current baseline and evidence. Set what is in and out of scope, the limits, the owner, and the time frame. Decision quality: Keep facts, guesses, and unknowns separate. Record the options you did not choose and what evidence would change the decision. Acceptance criteria: The document names an owner, target user, measurable result, scope limit, evidence source, open risks, and next test. Evidence and limits (evidence boundary): No single official standard controls the whole term. Its meaning may change across teams, platforms, or frameworks. Unknowns to confirm: Target group, baseline, success level, owner, time frame, dependencies, and review schedule.
