  2. 2. IntroductionThe London and Paris headquarters of BNP Paribas, the world’s largestbank, used our Transformation Manager software to deliver a new, fullyintegrated trading system for derivatives.• BNP Paribas’ Fixed Interest Derivatives team had to deliver a fully integrated and high performance system to support the bank’s business operation.• Derivatives are extremely complex financial instruments, with many terms, options, contract details and logic that must be embedded within them.• Because mistakes can cost millions of Euros, the need to keep risk to a minimum is vitally important.
