After World War II, the Japanese incrementally applied new management pract
ices to improve their global competitiveness. With refinement and systemati
c integration of these new practices the Japanese achieved a new manufactur
ing paradigm and, by the 1970s, a competitive superiority in the marketplac
e. In an effort to emulate the success achieved by Japanese manufacturers,
US managers began to apply these new management practices in their organiza
tions. These management practices were introduced as just-in-time (JIT) man
ufacturing. US managers have progressed through a series of trial and error
efforts to apply these new management practices and still do not understan
d many of the issues associated with JIT implementations. This study attemp
ts to address some of the misunderstandings associated with JIT implementat
ions. A systems approach is utilized for collecting data and analyzing pert
inent relationships associated with JIT implementations in US manufacturers
. Findings from the study suggest that an association exists between implem
ented JIT practices and type of production system. In addition, this is the
first study to show the benefits attributed to JIT implementation as a fun
ction of implementation status of specific JIT management practices and typ
e of production system. (C) 2001 Elsevier Science Ltd. All rights reserved.
