IEEE 1471 Standards Board approved the specification as IEEE Std 1471-2000. In 2006, ISO/IEC Joint Technical Committee 1 (JTC1), Information technology/Subcommittee SC 7, Software and systems engineering, adopted the specification as ISO/IEC 42010, under a special "fast-track procedure", in parallel with its approval by national bodies of ISO and IEC. A coordinated revision of this standard by ISO/IEC JTC1/SC7/WG42 and IEEE CS commenced in 2006, following the successful ISO/IEC fast-track ballot and in line with the IEEE standard 5-year review of the standard. In November 2011, IEEE 1471-2000 and ISO/IEC 42010:2007 was superseded by ISO/IEC/IEEE 42010:2011, "Systems and software engineering — Architecture
