The paper explores how work activity gets its orientation. With the help of Ilyenkov´s conception of the dialectical unity of activity/object and Leontiev´s conception of activity as layered, I make an analysis of patient cases presented in a clinical heart conference. The aim is to find out how the motivating character of the object of work influences the aggregates of work actions. The empirical finding is that ? and how - the transformations of the object occur in phases, which are determined by the practical encounter with the designed and redesigned objects. In the discussion of the findings three themes are presented. First, what constitutes the object of coronary clinical work, and how to describe and analyze it. Second, as one of the social actors which contribute to the configurations of the object, the voices of the patients which are heard in the clinical work are taken into account as one determination of the object of work.. Finally the paper discusses the instructive character of the transformation of the object of work.
