Product launch timeline
Gantt-style timeline for a three-month product launch — overlapping workstreams, two milestones, and a freeze window, used for exec status updates.
For the launch program manager
Scenario
The launch PM shares this in weekly exec status. Overlapping bars show where workstreams parallelize (design polishing while engineering still builds) and the feature-freeze diamond makes the handoff between build and QA unmissable. The second milestone (public launch) anchors the entire timeline and is the reason every other bar exists.

How to read
Time flows left to right. Horizontal bars are continuous work; diamonds are instantaneous events. Overlapping bars mean two teams are working simultaneously — fine, so long as they coordinate. The red Feature freeze marks the transition from net-new work to hardening; any engineering bar extending past it needs an exception. The green Public launch is the terminal milestone every other bar is serving.
