This chapter shifts the focus from the traders to the managers who supervised them. It considers in particular the issue of risk management through three different managers: the head of Risk Management at International Securities, a senior trader who was in charge of Todd's desk, and a manager whom Bob had tasked with promoting collaboration across desks. The challenges and difficulties these three individuals encountered revealed the organized and to some extent hierarchical nature of professional trading. It also highlights the need for an organizational lens. The chapter's observations of these managers also point to a difficult tension between technical and managerial expertise.
