Outsourcing has become the standard operating procedure for many U.S. government projects. However, the failure rate of these projects is high. For example, the Secure Border Initiative (SBinet), Affordable Health Care Act Exchange websites, and other projects have suffered failures leading to the complete termination of the project or a need to bring in another contractor to finish the work. These options increase costs for work that would have been done correctly if the project had been well managed in the first place. Using examples, identify and explain the problems that emerge from a project when the government allows the contractor to determine scope, manage all contractor relations, and decide how to share project status information with oversight bodies.
With the need to provide high-quality care to customers and decrease the costs of this provision, outsourcing has become one of the key solutions to these issues. However, due to the lack of control and additional disruptions, projects tend to have a greater likelihood of failing. Information Technology outsourcing is...
