| A plant with a SCADA, no execution system and no maintenance system | "We see the line. We know nothing about last night's production, or when that pump was serviced." | The complete EMS and CMMS on the existing PLCs; the SCADA replaced or kept beside; the record on top. | The whole plant on one database with no integration project. |
| An end-of-life SCADA, the renewal on the table | "The incumbent's renewal invoice, an unsupported Windows, a discontinued version." | Migration line by line, PLCs kept; EMS and CMMS as the reason to switch rather than renew. | The record, EMS and CMMS arrive with the migration, not as three more products. |
| Production on paper and spreadsheets | "A customer complaint, a lost batch, an audit, a new quality manager." | EMS: recipes through a quality door, orders on a calendar, jobs the line runs itself, the batch record. | A switch on the line, not a batch server; the plan is written to the line's own tags. |
| Maintenance nobody updates, or none at all | "A breakdown that cost a week, a maintenance system the technicians abandoned, spare-parts chaos." | CMMS: the type plants the package, meters folded from the run record, the phone technician, the signed close. | No data entry; the meter is a tag; a released job protects the availability number. |
| A regulated producer facing an audit | "Food, beverage, pharma, cosmetics, chemicals: a customer audit, a recall drill." | The record: signed recipes, batch certificates, electronic signatures, sealed reports, the maintenance record. | Frozen recipes per batch, hashed and signed documents, three languages, no report server. |
| A group with several plants | "The board wants one truth across sites; every plant reports differently." | The central backbone, cloud or a central server; one project per line; consolidated reports. | One product on-prem or cloud, the same migrations; a line travels as one file to the next plant. |
| A remote, harsh or air-gapped site | "Water, mining, utilities, oil and gas, defence: no reliable link, no cloud allowed, no IT on site." | The scripted install, the duty and standby pair, the emergency HMI. | The plant keeps its pages when the server is gone; licensed by two strings carried in and out. |
| A plant that must not stop | "A server failure that blinded the operators, a 24-hour line, an uptime clause from an insurer or a client." | High availability: duty and standby, the emergency HMI, a second edge on the same devices. | A dead server loses no plant data by construction; failover is calm, not a race. |
| A new line or machine being commissioned | "An OEM delivers a line; the plant wants it on its own system from day one." | The line's HMI imported as one file, the machine builder's maintenance package, EMS and EPS switched on at start-up. | Build once, travel anywhere; the type library carries the builder's knowledge. |
| Energy and cost pressure | "The energy bill, a sustainability report, a cost-per-unit question from finance." | Consumption and cost on the record, the dated rate book, downtime priced in money, per-batch used versus planned. | Energy is inside the record and EPS, not a different edition or a per-meter licence. |
