BSI Group, also known in its home market as the British Standards Institution (or BSI), is a multinational business services provider whose principal activity is the production of standards and the supply of standards-related services.

BSI Group was founded as the Engineering Standards Committee in London in 1901. It subsequently extended its standardisation work and became the British Engineering Standards Association in 1918, adopting the name British Standards Institution in 1931 after receiving its Royal Charter in 1929. In 1998 a revision of the Charter enabled the organization to diversify and acquire other businesses, and the trading name was changed to BSI Group.

The Group now operates internationally in 150 countries. The core business remains standards and standards related services, although the majority of the Group’s revenue now comes from management systems assessment and certification work.

Geoffrey Arnold "Jeff" Beck (born 24 June 1944) is an English rock guitarist. He is one of three noted guitarists to have played with The Yardbirds (Eric Clapton and Jimmy Page are the other two). Beck also formed The Jeff Beck Group and Beck, Bogert & Appice.

Much of Beck's recorded output has been instrumental, with a focus on innovative sound and his releases have spanned genres ranging from blues-rock, heavy metal, jazz fusion and an additional blend of guitar-rock and electronica. Although he recorded two hit albums (in 1975 and 1976) as a solo act, Beck has not established or maintained the sustained commercial success of many of his contemporaries and bandmates. Beck appears on albums by Mick Jagger, Kate Bush, Roger Waters, Donovan, Stevie Wonder, Les Paul, Zucchero, Cyndi Lauper, Brian May and ZZ Top. In 1988, he made a cameo appearance in the movie Twins.

He was ranked 5th in Rolling Stone's list of the "100 Greatest Guitarists of All Time" and the magazine has described him as "one of the most influential lead guitarists in rock".MSNBC has called him a "guitarist's guitarist". Beck has earned wide critical praise and received the Grammy Award for Best Rock Instrumental Performance six times and Grammy Award for Best Pop Instrumental Performance once. He has been inducted into the Rock and Roll Hall of Fame twice: as a member of The Yardbirds (1992) and as a solo artist (2009).
