What this page covers
- XER, MSPDI and MPP import path
- WBS tree, activity grid and Gantt
- The same schedule powers simulation
Engine / schedule
Schedule
A browser-based CPM schedule editor built for XER import, WBS navigation and QSRA-ready modelling.
Schedule / QSRA-ready CPM
A P6-class schedule editor, in the browser.
Import the programme, inspect WBS logic and work with a risk-adjusted Gantt. The schedule view is not a screenshot - it is the same model used by simulation.

DCMA-14 Schedule Health
The 14-point industry standard — logic, leads and lags, float, hard constraints, BEI and CPLI — scored pass/fail, with the dominant pressure surfaced first and an AI review on tap. A defensible health score, not a gut feel.
