ISA-95 draws the line every manufacturer lives with: Level 4 plans the business, Levels 0–2 run the machines, and Level 3 — manufacturing operations management — is where the plan either becomes product or falls apart. DO.Impact is that Level 3 layer for small and mid-sized plants, covering all four MOM pillars in one suite.
In short
DO.Impact covers the ISA-95 Level 3 MOM layer — production, quality, maintenance and inventory operations — in one suite: SIOP and finite scheduling down to hourly SIC execution, with quality, maintenance and material readiness in the same loop. 16 of 20 mapped activities managed end-to-end.

The Level 4 demand plan is checked against real capacity in SIOP, sequenced at finite capacity on the scheduling board, then paced hour by hour on the SIC board with loss codes — the full Level 3 production loop in one data model.
Quality is not a separate system. Escalations are contained first in the 3C loop, then driven to root cause in the Problem Solver, and the calibration module keeps measurement resources traceable — quality operations as ISA-95 intends.
The equipment register carries autonomous and planned maintenance, breakdown history and spares; MRO check scheduling covers heavy maintenance. Downtime feeds back into the schedule instead of surprising it.
DO.Impact does not replace your ERP or your machine controls. It is the operations layer between them: the plan comes in, performance goes back, and the Enterprise Network model shows how each part of the business couples to the next.
ISA-95 describes where each manufacturing function belongs. DO.Impact is a Level 3 manufacturing operations management system with a strong Level 4 connection: it plans, schedules, dispatches, tracks and analyses operations, and it hands off to Level 2 control systems rather than replacing them. Across 20 requirements: 16 managed end-to-end, 2 partly supported, 2 honestly outside the boundary.
| Area of the standard | Managed | Partly supported | Outside the boundary |
|---|---|---|---|
| Functional hierarchy — Levels 0 to 4 | 1 | 1 | 2 |
| Level 3 — Production operations management | 4 | 0 | 0 |
| Level 3 — Maintenance operations management | 3 | 0 | 0 |
| Level 3 — Quality operations management | 3 | 0 | 0 |
| Level 3 — Inventory operations management | 2 | 1 | 0 |
| Resource models | 3 | 0 | 0 |
Levels 0 to 2 — sensors, PLCs, SCADA and machine control — are outside DO.Impact. So is transactional ERP: order entry, invoicing and the general ledger. DO.Impact consumes and reconciles against them.
ISA-95 (IEC 62264) is the international standard that models how enterprise planning (Level 4) connects to manufacturing operations management (Level 3) and the shop floor (Levels 0–2). It defines four Level 3 pillars: production, quality, maintenance and inventory operations.
Manufacturing operations management (MOM) software runs the Level 3 activities between the ERP and the machines: detailed scheduling, work dispatch, production tracking, quality management, maintenance management and material movement. DO.Impact delivers these as one connected suite.
All four: production operations (SIOP, finite scheduling, shop floor execution, SIC), quality operations (escalations, problem solving, calibration), maintenance operations (equipment register, AM/PM, MRO) and inventory operations (material checks and kitting ahead of the schedule).
No. Transactional ERP (finance, payroll, serialised inventory) sits at Level 4 and SCADA/PLC control at Levels 0–2 — both stay in place. DO.Impact is the Level 3 operations layer that connects the plan to the floor and reports performance back up.
The model is, even if the paperwork is not. Small plants feel the same gap the standard describes: the plan in the ERP does not match what the floor can do. DO.Impact closes that gap with SIOP, finite-capacity scheduling and hourly execution tracking — without an enterprise MES project.
