ScheduleLens vs. Schedule Validator
Beyond the quality score: what delayed the programme, and why.
Schedule Validator scores P6, MS Project and Asta schedules in the browser and offers a free tier. ScheduleLens reads the same formats for a different job: delay analysis for extension of time claims, and named evidence of how an update was changed, priced per report.
ScheduleLens vs. Schedule Validator
Both run in the browser, both read P6, MS Project and Powerproject, and both compare a baseline with an update. The differences are in what the analysis is for and how you pay.
| Feature | ScheduleLens | Schedule Validator |
|---|---|---|
| Deployment | Web-based, no install | Web-based, no install |
| Formats | P6 .xer + .xml, MS Project .mpp + .xml, Asta .pp | P6 .xer, MS Project .mpp, Asta Powerproject |
| Delay analysis for EOT claims | Delay decomposition and critical-path shift; responsibility tagging on tracked projects | Not advertised |
| Update-integrity evidence | Named checks: progress claimed vs duration, Retained Logic / Progress Override switches, slip hidden by shortened durations | Manipulation detection advertised; checks not itemised |
| Written findings | AI narrative on every report; grounded Q&A on subscription plans | Custom narrative generation |
| Pricing | From $29 per report, plans from $79/month | Free Essential tier; Professional $600 per viewer per year |
Schedule Validator capabilities and prices are taken from its own website (September 2026) and may change. “Not advertised” means its public material doesn't mention it, not that the feature is missing. Schedule Validator is a trademark of its owner.
Which one fits your job
Some teams use both: continuous scoring across the portfolio, and a forensic report when a programme is disputed or a claim lands.
Schedule Validator is the better fit when
- You want every update of every project scored automatically, and the free tier covers what you need.
- You manage a portfolio and want one dashboard that ranks schedule quality across projects.
- You want to pull scores into your own reporting through an API.
- You run 25 or more projects and prefer a per-project enterprise subscription.
ScheduleLens is the better fit when
- You're preparing or assessing an extension of time claim and need the delay broken down, not only a quality score.
- You're checking a contractor's submission and need named evidence: progress claimed against duration, scheduling-mode switches, slip hidden by shortened durations.
- Your files arrive as P6 XML or MS Project XML as well as .xer, .mpp and .pp.
- You review programmes occasionally and would rather pay per report than per viewer per year.
