DCMA Schedule Assurance — Preflight Checklist
Use before uploading an XER or issuing an assurance report.

Purpose: confirm that scope, calculations and evidence are controlled before interpreting any percentage or RAG status. This checklist supports review; it does not replace contractual requirements or competent planning judgment.
1. Analysis population
- Correct XER file, revision and data date confirmed
- Selected P6 projects and project boundaries declared
- Completed, LOE and WBS-summary inclusion rules recorded
- Baseline and current schedule roles confirmed
- Eligible activity denominator shown for every metric
2. Logic integrity
- Missing predecessor and successor findings reviewed
- Open starts and finishes justified or corrected
- Leads, lags and relationship types tested
- Task-dependent zero-day relationships reviewed
- External project links retained as boundary evidence
3. Float and criticality
- Negative float activities and drivers identified
- High-float threshold and unit declared
- Critical path or longest path basis confirmed
- Multiple float paths checked where relevant
- Calendar effects on float understood
4. Constraints and dates
- Hard and soft constraints separated
- Constraint justification and approval evidence available
- Invalid actual/forecast date combinations checked
- Activities on the data date reviewed
- Missed work and out-of-sequence progress assessed
5. Durations, calendars and resources
- Long-duration threshold declared and exceptions reviewed
- Calendar assignments and working hours checked
- Non-standard calendars justified
- Resource/cost inclusion rules recorded
- Milestones and zero-duration activities classified correctly
6. Evidence and reporting
- Every finding can drill down to affected activity IDs
- Numerator, denominator and formula are visible
- Threshold changes affect status—not the finding engine
- Filters used for the issued result are recorded
- Report date, source revision and reviewer are traceable
