What used to be humanly impossible in schedules with thousands of activities now takes one click. Cleaner, more traceable and — above all — more defensible schedules.
Sign up in seconds with your email. No credit card. The 20 credits cover 4 redundancy cleanups.
The same schedule opened in Primavera. The difference isn't cosmetic: every line that disappears was logic that added nothing.
On the left, the original network saturated with logic links. On the right, the same schedule after removing the redundant relationships with XER-Cleaner.
Nearly 1 in 4 relationships is redundant: across 67 schedules processed with XER-Cleaner, 19% of relationships turned out to be unnecessary. In a network with thousands of activities and tens of thousands of relationships, identifying which ones are redundant means comparing every relationship against all possible paths in the network. It's an unfeasible task by hand — which is why nobody did it. XER-Cleaner automates it using graph transitive reduction, the same principle NASA and GAO describe when defining redundant logic.
This is what we've measured processing real schedules with XER-Cleaner:
Export your schedule from Primavera P6 and upload it. XER-Cleaner processes it directly — nothing to install, no need to touch your database.
The engine analyzes the entire logic network and identifies every redundant relationship, showing the alternative path that makes it unnecessary.
You get your clean schedule ready to use, plus the reports to review and back up every change.
A copy of your XER with the redundant relationships already removed, ready to import back into Primavera P6.
The detail of every relationship —predecessor, successor, type, lag and the path that justifies it—, classifying the detected redundant links, the protected ones and the removable ones. Ready to apply the deletions by pasting the data into an xlsx exported from P6.
The app can email you both files directly, with a summary of the findings in the message body — a dated record that works as documentary evidence.
Redundant relationships hinder traceability and critical-path tracing —exactly what holds up your schedule as evidence in a dispute—. XER-Cleaner leaves your logic network clean, aligned with NASA, GAO and CIOB best practices. See the evidence →
Sign up free, get 20 credits —enough for 4 cleanups— and process your first XER today. The number will probably surprise you.
