Milestone diamonds
Checkpoint markers with due date and status. One click opens the milestone detail view.
Timeline
Timeline that understands dependencies
Dependency arrows show which task blocks the next milestone. Move a task, dependent successors slide along automatically. Milestone diamonds mark checkpoints — rendered as native SVG.
Zoom levels
Day, week, month — no reload
Three zoom levels adapt bar density to the planning horizon. Zoom to day for the weekly standup, to month for the quarterly plan. No reload, no context switch.
- Day zoom: bars per day, task labels visible
- Week zoom: five days per column, default for operational planning
- Month zoom: milestones prominent, for quarterly reviews
- Scroll position is preserved when zooming
Dependencies
Circular dependencies are blocked
If task B waits for task A, and task A is suddenly meant to depend on task B: lumen.pmo prevents creation. You get a clear error message, not a deadlock.
- Graph check on save — not first on Gantt render
- Visual arrows with status colours (met, open, blocked)
- Cascade shift optional: a predecessor shift moves successors with it
- Export of the dependency graph as JSON or CSV
Building blocks
What makes the timeline work
Task hierarchies
Subtasks are rendered indented and collapsible. Parent tasks aggregate the progress of their children.
Progress bars
Bar fill shows completion percent. Red when overdue, grey for draft, teal for in progress.
Demo
Show us your most complex project
In a 30-minute demo we import an export of your current project (CSV/MS Project/etc.) and render it live as a timeline. You see the difference directly — no marketing mockup.
