You already know this workflow is broken.

The PFD is in Visio. The parameters are in Excel. The version everyone reviews is a PowerPoint.
When one step changes, you update everything by hand, hoping nothing drifts out of sync.
PharmaDiagrams puts it all in one place.

TMP upper limit should be 1.5 bar per membrane supplier specs. The diagram still shows 2.0 bar from the old Pellicon 2 cassettes — we switched to Pellicon 3 last quarter.
