This paper describes a qualitative study of how people use their time at wo
rk, why they use it this way, and whether their way of using time is optima
l for them or their work groups. Results of a nine-month field study of the
work practices of a software engineering team revealed that the group's co
llective use of time perpetuated its members' "time famine," a feeling of h
aving too much to do and not enough time to do it. Engineers had difficulty
getting their individual work done because they were constantly interrupte
d by others. A crisis mentality and a reward system based on individual her
oics perpetuated this disruptive way of interacting. Altering the way softw
are engineers used their time at work, however, enhanced their collective p
roductivity. This research points toward a "sociology of work time," a fram
ework integrating individuals' interdependent work patterns and the larger
social and temporal contexts. The theoretical and practical implications of
a sociology of work time are explored.*
