Direct answer
Write a line-level specification with acceptance criteria, then procure packages against it with one accountable owner for interfaces and system acceptance.
How this problem shows up
- New product or format needs dedicated capacity
- Existing lines cannot be modified without losing output
- Committed volume justifies dedicated equipment
- Multiple suppliers will be involved
- A firm production start date exists
Engineering responses
Turnkey line
One contractor, one performance guarantee, price premium.
Package procurement with integrator
Buyer selects machines, integrator owns interfaces.
Replicate an existing line
Lowest risk where an internal reference line performs well.
Engineering and project considerations
- Availability assumptions per station must be evidenced, not assumed
- Buffers sized from micro-stop data, not intuition
- Interface control document before ordering
- FAT and SAT criteria written into contracts
- Ramp-up curve agreed with operations and reflected in the business case
What to prepare before engaging engineering companies
- Product specification and SKU roadmap
- Takt and availability targets with evidence
- Layout, utilities and access constraints
- Acceptance protocol draft
What to measure
Output at acceptanceRamp-up durationCapital per unit of annual capacity
Frequently asked questions
What derails new lines most often?
Under-specified interfaces and optimistic availability assumptions. Both are inexpensive to fix on paper and very expensive after installation.
