Which actions is most appropriate for an outsourced item that has been judged to fall in the leverage quadrant of a portfolio​ analysis?

The correct answer to the following question will be to "Promote competitive bidding".

Explanation:

The easiest, most successful way of creating competition would be to apply for two or even more published offers (three offers are desired and are therefore not necessarily feasible). This approach determines the manufacturer chosen delivers products and services during the most value-effective way possible. This could be especially useful for a privatized element that has already been determined to fall within a portfolio evaluation leveraging constellation.

Therefore, it's the right answer.
