In product-based tailored sourcing, 1.low-volume products with uncertain demand are obtained from a flexible source. 2.high-volume products with less demand uncertainty are obtained from an efficient source. 3.high-volume products with less demand uncertainty are obtained from a flexible source. 4.low-volume products with uncertain demand are obtained from a flexible source and 5.high-volume products with less demand uncertainty are obtained from an efficient source only

The best answers are Option 4 & 5

low-volume products with uncertain demand are obtained from a flexible source, while high-volume products with less demand uncertainty are obtained from an efficient source

Explanation:

Tailored sourcing does not necessarily mean buying from two different sources it just makes use of a combined supply source.

One might be at a lower cost but is unable to deal with uncertainty well and the second more flexible but is at a higher cost.

Tailored sourcing may be volume-based or product-based depending on the source of uncertainty.
