In 2000, the FBI began the Trilogy project to upgrade its outdated information technology (IT) infrastructure. This project, originally scheduled to take three years and cost around $380 million, ended up going far over budget and behind schedule. Efforts to deploy modern computers and networking equipment were generally successful, but attempts to develop new investigation software, outsourced to Science Applications International Corporation (SAIC), were not. Virtual Case File, or VCF, as the software was known, was plagued by poorly defined goals, and repeated changes in management. In January 2005, more than two years after the software was originally planned for completion, the FBI officially abandoned the project. At least $100 million (and much more by some estimates) was spent on the project, which never became operational. The FBI has been forced to continue using its decade-old Automated Case Support system, which IT experts consider woefully inadequate. In March 2005, the FBI announced it was beginning a new, more ambitious software project, code-named Sentinel, which they expected to complete by 2009.
