SCHEDULE VALIDATION FAQ
Questions project teams ask before uploading.
What is project schedule validation?
Schedule validation reviews activity logic, relationships, float, constraints, calendars, progress and critical-path continuity to reveal issues that can weaken a project forecast.
Which schedule formats are supported?
PlanProof is designed for Primavera P6 XER, Microsoft Project MPP and Asta Powerproject PP files. The current public release demonstrates the validation workflow while production parsers are connected.
What is included in the free validation?
Your first validation includes the health score, detailed detected errors, affected areas, severity levels, and recommended corrective actions. No credit card is required. Payment is requested only for additional validations.
Who is PlanProof for?
It is designed for project planners, schedulers, project-controls teams, contractors, owners and consultants working across construction, infrastructure, energy and industrial projects.
What does the schedule health score measure?
The score summarizes checks across schedule logic, negative and excessive float, constraints, critical-path integrity, calendars and progress quality.
Can PlanProof replace a planner's judgement?
No. It helps planners find and prioritize evidence faster. Contract requirements, project context and professional judgement remain essential.
