1961–1995

Technology Acceptance Paradigm

Contemporary themes

Information technology during 1961-1995 was conceptualized as a strategic resource enabling planning, cross-organizational integration, and innovation in market structures such as electronic markets and interorganizational information systems. Adoption, usefulness, usability, and satisfaction with information technology were framed as key determinants of system use, performance, and organizational value, with measurement instruments and attitude studies shaping user-centric design. IS acted as both a driver and a barrier to organizational change, with emphasis on implementation bridging, governance, post-implementation control, and the social organization of computing. A suite of management information systems research frameworks emphasized planning, knowledge management, and technology policy guiding computer-based management information systems research, while quantitative assessment of user satisfaction and system performance informed iterative development and practice.
