Logic
Open ends, relationship integrity, leads, lags and links that need review before the schedule is relied on.
Primavera P6 · XER · schedule assurance
Do not buy a schedule health score. Buy the evidence needed to correct the schedule.
XERR DCMA Schedule Assurance keeps population, calculation, tolerance and affected activity evidence visible together so planners, PMOs and assurance teams can challenge a finding, correct the records and retest the result.

Interface proof
See the metric, denominator and affected records together.
The working XERR interface is built around the evidence behind the result rather than a single opaque quality score. Visitors can inspect the controlled synthetic sample before deciding whether to request a trial.
What the review covers
Review schedule structure before the dates become the decision.
A schedule can look credible while logic, float, constraints or date conditions are weakening the forecast. XERR keeps the diagnostic finding and affected records together.
Float
Negative float, high float and the activities driving an abnormal result.
Constraints
Hard and soft constraints with the underlying activities visible for review.
Dates
Data date behaviour, invalid date conditions, missed work and other timing evidence.
Population
Make the selected projects and eligible population visible so the denominator can be challenged.
Evidence
Move from a headline metric to the affected activities, explanation and corrective action.
Why buyers use this route
The result remains explainable when somebody challenges it.
Declared scope: see which project population is being checked before interpreting any percentage.
Visible numerator and denominator: understand exactly how each metric was produced.
Activity level evidence: inspect the records creating the finding instead of receiving only a red/amber/green badge.
Controlled tolerance: thresholds classify the finding without changing which activities the engine identifies.
Correct and retest: use the finding as a focused correction list and verify whether the schedule actually improved.
