Jeffrey Zients told reporters in a conference call that Quality Software Services, or QSSI, will serve as a general contractor to oversee the repairs. The website hasn't had a technology company overseeing the entire project. Instead, the government decided early on that the Centers for Medicare and Medicaid Services would serve as the system integrator.

Online insurance exchanges were launched on Oct. 1 under the 2010 Affordable Care Act, often called "Obamacare," to offer health care insurance plans to millions of uninsured Americans. But many Americans have experienced error messages and long waits in trying to sign on to HealthCare.gov, which has become a political embarrassment for Obama.
"By the end of November, the vast majority of consumers will be able to successfully and smoothly enroll through HealthCare.gov," Zients said.
