The problem

Scheduling software is restricted on purpose — and that's exactly what breaks it.

Primavera P6 and Microsoft Project are deliberately locked to a trained planning function. An untrained edit to predecessor/successor logic can corrupt the critical path across an entire programme, so access stays narrow. The same design choice that protects the schedule also cuts it off from the people who see problems first.

Where the lag comes from

The delay is structural, not a communication failure.

Why existing tools don't close it

Enterprise software solves its own domain. Nobody reasons across them.

Primavera / MSP

Manages the schedule — assumes information already reached the planner.

ALICE

Optimises sequencing once the schedule is current — doesn't solve how it becomes current.

SAP / ERP

Records financial and procurement transactions in its own silo.

Power BI

Visualises whatever data it's given — after the fact.

Agile ceremonies

Adds stand-ups and tracking overhead on top of the same siloed departments.

Realyst

Reads the signal where it already lives and routes it to the schedule — the layer that was missing.
