Researchers and practitioners have acknowledged the need to understand caus
al relationships among various elements of total quality management (TQM).
In this paper, we model TQM as an organizational innovation. Using the inno
vation diffusion perspective from the information systems and organizationa
l innovation literature, we theorize that TQM implementation translates top
management's quality intent into plant-level operational performance throu
gh a four-stage process of adoption, adaptation, acceptance, and use. The t
op management adopts the TQM philosophy in the first stage. This commitment
influences the adaptation of the organizational members' ability and attit
ude to the new quality management philosophy. In the acceptance stage, the
organizational members demonstrate acceptance of the new quality focus thro
ugh cooperative teamwork, relationships with suppliers, and quality-related
learning. The diffusion of the new philosophy is confirmed through routini
zation of core quality improvement through effective design, tracking, assu
rance, and improvement of quality. The four-stage transformation process le
ads to plant-level measures of product and process quality. We tested this
framework on a sample of 407 plants in the automobile parts suppliers indus
try and found good support for the model. Our results suggest that firms sh
ould ensure appropriate technical and behavioral preparation of employees a
nd suppliers before and concurrent to actual TQM implementation. Furthermor
e, the results also suggest that firms should implement TQM in an integrate
d fashion covering all sociotechnical elements detailed in our framework. I
mplications of these findings for TQM practice and research are discussed.
