An EMS provider is a process owner. The assembly line is the visible part; the review, sourcing and test around it decide the outcome.

DFM and DFA review before tooling, stackup and impedance advice, and a clear answer on what the process can hold.
Whole-BOM purchasing, incoming inspection and life-cycle checks that surface obsolete parts before the line stops.
SMT and through-hole assembly, AOI, X-ray, ICT or flying probe, functional test and burn-in where the product needs it.
Lot traceability from material to shipment is what makes a warranty claim resolvable.
Whether the engineering review happens before tooling, how components are sourced and inspected, which test methods are in-house, and whether lot traceability survives to shipment. A line tour answers less than a walk through the quality records.
Splitting adds a hand-off where design data and responsibility can drift, and it usually adds lead time. Keeping both under one roof means one schedule and one owner for a defect that appears after assembly.
