ERP / MRP BUSINESS CASE
Manufacturing ERP Total Cost of Ownership Guide
Build a comparable manufacturing ERP or MRP cost model covering subscription, implementation, data migration, integration, training, internal labor and operating change rather than software price alone.
Cost model
- Separate recurring software and support from one-time implementation, migration, integration and training costs.
- Include internal planner, engineering, production, finance and IT time needed for data cleanup, testing and cutover.
- Model a realistic analysis period and document which optional modules, users, sites and transaction volumes drive future cost.
Operational value
- Tie expected value to measurable operating outcomes such as schedule adherence, inventory accuracy, planner effort, purchasing response and work-order visibility.
- Avoid treating generic vendor benefit percentages as project evidence; use baseline plant data and explicit assumptions.
- Separate cash-flow effects such as inventory release from true annual operating savings.
Selection evidence
- Require scenario demonstrations with representative bills of material, routings, inventory records and production orders.
- Score data ownership, APIs, integrations, exportability, backup and change control before commercial negotiation.
- Use acceptance criteria and a controlled pilot to validate the business case before wider rollout.
