As May Day approached, Z/Yen planned how to carry out work in the Square Mile without attracting the attention of anti-globalisation protestors.Jeremy Smith, who had a formal public speaking engagement in the afternoon, came to work in dreadlocks and old combat trousers (no change there then - Ed) before changing into his svelte pinstriped suit (when did he buy that? – Ed) .Despite the costumes, Z/Yen has won a number of new assignments in the City for banks and clearing houses.For these projects, Jeremy Smith, Michael Mainelli, Giles Wright and Francesca Birch are supplemented by new associates Derek Long, David Pearce and Francis Hellawell. The assignments include a number of demanding projects ranging from establishing the benefits of clearing houses, through cost-per-transaction benchmarking, to the structure of product control and accounting in investment banks.
