What this resource helps you evaluate
mid-market plants connecting planning systems to shop-floor execution translating operating needs into a structured MES for Mid-Market Plants requirements list.
Requirements should describe the decision, control or workflow outcome that matters. For mes for mid-market plants, broad statements such as “easy integration” or “good reporting” should be replaced with testable acceptance criteria.
What to compare first
- Coverage of dispatching, operator execution, traceability, downtime and production reporting
- Integration, data ownership and reporting needed by mid-market plants connecting planning systems to shop-floor execution
- Implementation effort, support model and total lifecycle cost
- Security, auditability, permissions and recovery requirements
- Evidence from a pilot using representative production lines
- Non-functional requirements for performance, availability, identity and data retention
Step-by-step process
- 01
Map users, roles, systems, data objects and critical exceptions.
- 02
Write each mandatory requirement as a testable outcome.
- 03
Add volume, response-time, retention and availability assumptions where relevant.
- 04
Mark each requirement as native, configured, integrated, customized or unsupported during evaluation.
- 05
Carry accepted requirements into implementation testing and contract scope.
Common mistakes and risk checks
- deploying MES without a clear equipment, routing and data ownership model.
- Comparing headline license price without implementation, integration, migration and support cost.
- Scoring demos instead of validating the highest-risk workflows with real data and users.
Documents and evidence to collect
- Requirements catalogue
- Integration and interface list
- Data dictionary
- Role and permission matrix
- Acceptance-test traceability matrix
Questions to ask vendors
- Can the vendor demonstrate dispatching, operator execution, traceability, downtime and production reporting with our representative data?
- Which capabilities require paid modules, services or third-party products?
- What data can we export in a documented format if we leave?
- What implementation work is performed by the vendor versus the customer or partner?
- How are support response, releases, backups and security responsibilities defined?
