Drag the bar. Watch the finish move.
An interactive Gantt — critical path, baseline overlay, WBS bands, four timescales — with a what-if mode that reschedules the whole chain through real P6 calendars as you drag.
Built for programme review, not slideware.
The engine reads each activity’s own P6 calendar — weekday patterns, holidays, even working exceptions like weekend shifts.
Move, stretch, link — rescheduled live.
Drag a bar and the whole chain reschedules through the CPM engine — existing FS/SS/FF/SF logic, lags and per-activity calendars honoured. Drawing a new dependency creates an FS link; loops are blocked; completed work stays locked. When the scenario wins the meeting, export the change-sheet and apply it in P6 or MS Project.
Scenarios that survive the update cycle.
Each scenario is saved against the exact monthly update it was built on — next month’s XER doesn’t overwrite your thinking.
Also plan visually.
A Calendar month view with a working-time inspector, and a Kanban with WBS swimlanes. Dragging a card between status columns feeds the CPM projection — it isn’t just a board.
