Open ends and logic
Find activities with missing predecessors or successors and inspect relationship lag that can conceal or distort the driving sequence.
Browser-based schedule analysis software
Find schedule problems before they become project problems
Check a P6 XER for missing logic, constraints, float, out-of-sequence progress, and dates that conflict with the data date. Review exported longest-path status, resources, calendars, and milestones. Keep successive updates in one project record to analyze schedule change across the full duration of the project.
What the schedule analyzer reviews
Checks for details that distort schedule forecasts
Schedule Tracker reads native XER activity, relationship, calendar, resource, and project data. It does not edit the source file or recalculate the CPM network. Each finding connects summary metrics to the underlying schedule evidence.
Float and longest-path status
Review P6 longest-path status, activities at zero or negative total float, and the dates associated with each result.
Constraints and invalid dates
Surface constrained activities and actual start or finish dates recorded beyond the schedule data date.
Out-of-sequence progress
Identify work performed outside the planned predecessor-successor sequence and review the affected logic.
Milestones and float
List project milestones by WBS, highlight negative float, and keep contractual and intermediate dates visible.
Activity data quality
Find duplicate activity descriptions and inspect actual dates, original durations, calendars, and task-level schedule fields.
More than activity dates
Calendars, resources, work, and costs
A schedule can appear sound at the activity level while still relying on unrealistic assumptions about working time, resource demand, or costs. Review the supporting calendar, resource, and cost data to assess those assumptions.
- Calendar workweeks, exceptions, and holidays
- Project resources and assigned activities
- Labor resource overallocation by month
- Project milestones grouped by WBS
- Activity cost details and project cost curves
- Planned, remaining, total, and completed work

Frequently asked questions
Practical answers for P6 schedule reviewers
What does schedule analysis software do?
Schedule analysis software checks schedules created in a planning system such as Primavera P6. Schedule Tracker reads XER exports and reports schedule-quality findings with the activity data behind them. It leaves the source file unchanged and works alongside P6.
What does a Primavera P6 schedule health check review?
Schedule Tracker reviews CPM data including open ends, relationship lag, constraints, negative float, critical and longest paths, future actual dates, out-of-sequence progress, calendars, resources, costs, and milestones.
Do I need a connection to the Primavera P6 database?
No. Upload an XER export through a modern web browser. Schedule Tracker does not require a direct P6 database connection or a Windows-only desktop installation.
Which Primavera P6 XER files are supported?
Schedule Tracker supports XER exports created by Primavera P6 version 7.0 or newer. The project should be scheduled in P6 before export so its calculated dates are available for analysis.
Is this a complete DCMA 14-point assessment?
Schedule Tracker reports all 14 points, with measured results, thresholds, and supporting findings where the required evidence is available. The Critical Path Test requires network recalculation, so it is marked not evaluated. The results are diagnostic schedule-quality findings; they do not certify the schedule or determine contractual compliance.
