This paper examines new dimensions of professional-organizational rela
tions through the concept of trust. It develops the argument that trus
t exists among similar professionals because of many common denominato
rs that lubricate their intra- and interorganizational collaborations.
Therefore, professionals have the ability to conduct efficient transa
ctions that reduce the need for formal monitoring systems and costly c
ontractual agreements. These efficiencies in turn contribute to organi
zational goals of efficiency, flexibility, and legitimacy because they
reduce organizational costs, increase organizational learning, allow
for faster organizational adjustment to environmental changes, and acc
ommodate professionals' desire for sovereignty. Concomitantly, profess
ionals impose their own needs for autonomy on organizations. Consequen
tly, professionals both impel the creation of new organizational forms
, and contribute to the efficiency of these forms. In particular, thre
e such forms-fiat structures, hypertext organizations, and network for
ms-are facilitated and engendered by professionals.
