all I can tell you is that Accenture uses sub-contractors.
According to a well-known industry research company:
Accenture, in addition to in-house workforce, makes use of subcontractors to execute contracts.
Accenture has faced problems with subcontractors on
some of its major contracts e.g. Maximus ( subcontractor of Accenture for work on a Texas Health
and Human Services Commission program in 2006)
