This morning he spent two hours in budget sessions with Finance, and another hour meeting with the vendor of an important production component. His team had discovered a problem with the component yesterday, and he knows how critical it is to the quality of the finished product. On a typical day, Carl will spend about three hours contending with influences from groups both inside and outside the company.
