Re: "poison for slow, traditional businesses"
Most giants of any sort are still "slow", Agile™ or not. Tesco, Barcs, whoever - they always have legacy garbage fires smouldering away somewhere that make any change a long string of "but what about X?" questions that take time and money to answer.
If you're lucky, those questions happen in planning rather than halfway through implementation.
