leverage brand, proven diagnostic and metrics

[user_gary]

Although you might hear multiple definitions in the marketplace,
Futurestep defines RPO as a highly customized, fully integrated single-source
solution in which expert consultants manage all of a client’s human
capital requirements, either on-site from their location or from the
provider’s. The goal is to attract the highest-quality talent while also
bringing improved processes and efficiencies to the organization. To do
this, providers leverage brand, leading-edge technology, proven
diagnostic and metrics, and their global reach.

Please explain the emboldened parts.

I am sorry but this is jargon and is barely English, "...providers leverage brand, leading-edge technology, proven
diagnostic and metrics, and their global reach."
