Overview

Timelines go wrong when dates appear without owners, dependencies or any sign of which ones can move. This deck shows the whole project on one milestone line, then a swimlane roadmap, the critical path and a launch plan, with fixed and flexible dates marked.

The sample is the 29-week rebuild of a ferry booking site by Zephyrine Digital, from 11 January to 30 July 2027, with go-live fixed for 19 July. The critical path is 19 weeks, 66% of the project. Replace the axis, phases, milestone dates, owners and assumptions with your own.

Useful for

  • A project manager showing a sponsor the phases, the next milestone and the fixed go-live date
  • A delivery lead explaining which tasks sit on the critical path and which have float
  • A team planning a 12 to 16 week launch countdown with several workstreams

What's included

  • Cover slide with the project name and the span of the plan
  • Milestone timeline with five dated gates and progress marked
  • Swimlane roadmap with four lanes, four periods and a marker for today
  • Phase, milestone and dependency slides that show the critical path and float
  • Key dates and launch-week slides with hour-by-hour detail
  • Hypercare support slide, a guide slide and a contacts slide

    Replace the milestone dates, mark which are fixed, and add the owner of each.

Questions

How many milestones should a project timeline show?

Six to twelve, with two or three flagged as fixed. More than that and the slide becomes a task list. Keep detail for an appendix and show phases, gates and the critical path.

Is Zephyrine Digital a real company?

No. The organisation, the people, the client and every date and figure in the deck are fictional sample data, written to show a complete timeline. Replace them with your own.

Can I use it for something other than software?

Yes. The same layout suits a building project, an event, a product launch or a house move. Change the lanes and phases, and keep the fixed dates and the critical path.
