In brief
Make-or-buy is more than a unit-cost comparison. Strategic relevance, quality, delivery, know-how, investment, scalability and dependency can change the decision.
What does manufacturing strategy decide?
It defines which value creation remains internal or external, which technologies and capabilities are required and how they are distributed across sites. It therefore provides the strategic frame for production and factory planning.
Define the decision boundary
The analysis starts with product or component family, process scope, horizon, volumes and sites. A narrow unit-cost comparison omits quality cost, logistics, inventory, coordination, ramp-up and risk.
Strategy
Differentiation and core capability
Economics
Total cost and investment
Performance
Quality, time and scalability
Risk
Dependency and resilience
Total cost rather than purchase price
Variable and fixed manufacturing cost, investment, tooling, quality, scrap, logistics, inventory, coordination, supplier management, ramp-up and phase-out are compared. One-off transition cost is separated from recurring cost. Scenarios show how volume, utilisation, labour or transport changes the ranking.
Non-monetary criteria
| Criterion | Question |
|---|---|
| Know-how | Which capability must remain or be built internally? |
| Quality | How controllable are capability and traceability? |
| Delivery | Which response time and volume flexibility are required? |
| Technology | How mature and transferable is the process? |
| Risk | Which dependencies and single sources exist? |
| Site | How do people, energy, infrastructure and proximity matter? |
Options beyond a binary decision
Partnerships, dual sourcing, licensing, extended workbench, internal critical steps or phased industrialisation can be evaluated alongside pure make and buy options.
From decision to roadmap
The preferred option becomes capability building, investment, supplier development, qualification, transfer, ramp-up and decision gates. Only then is it translated into capacity, space and layout through factory planning.
