Trend & delay analysis across updates · ScheduleSignal
Track · Trends, Comparison & Delay

What moved since last month — answered in writing.

Drop each month’s XER — the app recognises it as an update of the same P6 project and files it automatically. Four trend charts and a written narrative explain the movement.

Update hygiene

One project, filed monthly — automatically.

The library matches updates by P6 project id, then project name, then file name. One update per data date; re-imports replace cleanly instead of duplicating history.

The four charts

Four charts, one story: where the finish is heading.

Every monthly update becomes a data point — the drift is visible long before it becomes a claim.

The narrative

Written by the app, ready for the meeting.

Sample — as generated for one update pair
“Forecast finish moved +9 days (14-May → 23-May). Driving the movement: A1030 ‘Pile caps zone 2’ slipped +11d on the critical path. Entered the critical path: A2210, A2230.”
Delay analysis · for the consultants

Prove what slipped, when and why.

Baseline-vs-current finish variance, slipped activities ranked by an impact score, WBS slippage, missed actuals, CPLI and BEI — traced update by update, exportable as evidence.

Finish variance Drivers ranked by impact WBS slippage Missed actuals CPLI & BEI Forensic windows

Delay drivers ranked by impact — finish variance, float and flags per activity.

Honest scope: this is window-by-window observational analysis across your updates — it does not build TIA fragnets. That limit is documented in the pricing FAQ, not hidden in fine print.

Two-file comparison

Any two XERs, diffed for the record.

For ad-hoc questions outside the monthly cycle: compare any two exports directly, then take the CSV with you.
