Before you benchmark OEE across plants or clean up reason codes, check whether the formula itself is being calculated right — most drift happens in ideal cycle time, downtime buckets, and micro-stops.

Forward vs. Backward Genealogy: Why Your MES Probably Only Answers Half the Recall Question
Most MES systems can answer either “what’s in this unit” or “where did this lot go” quickly, but not both. Here’s how the two traceability directions actually work and how to model your data so a recall doesn’t turn into a week of spreadsheet archaeology.
Read MoreWhy Your MES Work Order Model Shouldn’t Look Like Your ERP’s
Most MES projects go sideways because someone copied the ERP’s work order structure into the MES and called it a model. Here’s how to actually scope one, using ISA-95 as the backbone.
Read MoreLevel 3 vs Level 4: The ISA-95 Boundary Vendors Keep Asking You to Forget
As vendors pitch MES/ERP “convergence” as a feature, the ISA-95 Level 3/4 boundary is getting harder to see. Here’s how to re-draw it, and a three-question test for any convergence pitch.
Read MoreYour Equipment Hierarchy Is Fine. Your B2MML Messages Are Probably Not.
Every MES project studies the ISA-95 equipment hierarchy and calls it a day — but the actual contract that keeps MES and ERP talking is the B2MML transaction set, and almost nobody validates it. Here’s how to do that properly.
Read MoreWhere to Put the Signature: Designing E-Signature Logic for Batch Records in MES
As low-code MES batch execution modules push e-signature configuration onto plant IT teams for the first time, here’s how to draw the line between what needs a signature and what just needs a record.
Read MoreBuilding the ISA-95 Equipment Hierarchy: A Practitioner’s Guide to Getting Week One Right
Most MES projects don’t fail because of the software—they fail because the equipment, material, and personnel hierarchy was sketched out in week one and never touched again. Here’s how to actually build one.
Read MoreReview by Exception: How to Actually Design It, Not Just Turn It On
Review by exception is usually configured as a vendor checkbox, not a designed workflow — here’s how to actually build the ruleset so batch release gets faster without getting riskier.
Read MoreFour Things Called “Work Order,” and Why Your ERP and MES Don’t Agree
Everyone says “work order” but means something different — the ERP production order, the MES dispatch record, the routing step, or the equipment job. Here’s how to tell them apart and stop the reconciliation headaches.
Read MoreEveryone Cites ISA-95. Almost Nobody Has Implemented Part 3.
Most “ISA-95 compliant” claims are really just Part 1’s pyramid diagram with none of Part 3’s detailed activity models behind them. Here’s how to check what’s actually configured before you sign.
