MRP / SMALL MANUFACTURING

Job-Shop MRP Software Requirements Guide

Define practical MRP software requirements for make-to-order and mixed-mode manufacturers before comparing vendors, subscriptions or implementation proposals.

Production model

  • Document whether work is make-to-order, make-to-stock, engineer-to-order or mixed-mode before evaluating software.
  • Require routing, work-center, setup, run-time and outside-processing data structures that match the real production flow.
  • Define how substitutions, scrap, rework and partial completions are represented rather than relying on a clean-demo process.

Planning and inventory

  • Verify material requirements, purchase suggestions and shortage visibility against realistic bills of material and lead times.
  • Define lot, serial and revision traceability requirements before importing inventory.
  • Test how capacity constraints, due dates and priority changes propagate into purchasing and production plans.

Integration and acceptance

  • Map ownership of customer, item, routing, inventory, quality and financial data across ERP, MRP, MES, accounting and shop-floor systems.
  • Run a pilot using representative orders and actual master data, not only vendor sample data.
  • Define measurable acceptance criteria such as schedule adherence, inventory accuracy, planner effort and transaction completeness.
