Federal officials did not permit testing of the Obamacare healthcare.gov website or issue final system requirements until four to six days before its Oct. 1 launch, according to an individual with direct knowledge of the project.
The individual, who spoke on condition of anonymity, described the troubled Obamacare website project as suffering from top-level management disarray, changing systems requirements and recurring delays.
The root cause of the problems was a pivotal decision by Centers for Medicare and Medicaid Services  officials to act as systems integrator, the central coordinator for the entire program. Usually this role is reserved for the prime information technology contractor.
As a result, full testing of the site was delayed until four to six days before the fateful Oct. 1 launch of the health care exchanges, the individual said.
