US Digital Service and the current White House MO around digital service delivery [1] operates a bit differently. IRS modernization [2] [3] will be owned internally. Their systems are the iceberg under the surface, the website for citizen consumption is the little bit above the surface. They're hiring people who know what they're doing (from page 15 of the modernization pdf):

> Our overall success will depend on several special legislative proposals and regulatory authorities that we believe are appropriate for an effort of this scope and importance:

> Engaging the Office of Personnel Management to utilize existing direct hire authority for IT modernization positions and/or broadening government-wide critical pay authority

> Seeking reauthorization of IRS Streamlined Critical Pay Authority that expired in 2013

> Ensuring funding is available for multiple fiscal years at somewhat predictable intervals.
