What this resource helps you evaluate
job shops and low-volume high-mix manufacturers translating operating needs into a structured Job Shop MRP requirements list.
Requirements should describe the decision, control or workflow outcome that matters. For job shop mrp, broad statements such as “easy integration” or “good reporting” should be replaced with testable acceptance criteria.
What to compare first
- Coverage of quote-to-job conversion, routing, scheduling, WIP and delivery control
- Integration, data ownership and reporting needed by job shops and low-volume high-mix manufacturers
- Implementation effort, support model and total lifecycle cost
- Security, auditability, permissions and recovery requirements
- Evidence from a pilot using representative planners
- 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
- planning with inaccurate setup times, queue times or work-center calendars.
- 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 quote-to-job conversion, routing, scheduling, WIP and delivery control 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?
