| Summary: | In the world of business, information technology (IT) continues to heighten
competencies and ensure success of firms. But, investment in the emerging IT can
lead to productivity gains only if it is accepted and effectively used. As a
consequence, IT acceptance and utilization represent central concerns in recent
information systems research. Therefore, the main objective of this research is to
examine the influence of external variables on IT acceptance (Le., usage), and how
IT acceptance contributes to a firm's ability to be an agile competitor.
This research is an empirical attempt to investigate the influence of IT
acceptance and usage on agility, based on a well-established theoretical model, that
is, Technology Acceptance Model (TAM) from the management information
system area. TAM was chosen as the theoretical basis (paradigm) within which an
extended model was formulated. A few adaptations to this paradigm were
introduced in order to make them applicable to the present context building upon,
and integrating previous researches in a cumulative manner. This led to a research and integrating previous researches in a cumulative manner. This led to a research
model which was tested by a seventeen-page survey questionnaire. This research
used results from a survey among 329 managers and executives in manufacturing
firms in the Klang Valley, Malaysia.
A careful confirmatory factor analysis (CFA) and a reliability analysis
(Cronbach's alpha coefficient) for the measure used in the survey were conducted.
Correlation analysis, multiple regression analysis, and structural equation modeling
(SEM) analysis using AMOS 4.0 were used as different data analysis techniques.
The analysis in part gave good support for the initial model considered, but also
revealed some shortcomings in the base model (TAM).
The findings from this research indicated that information quality is a
dominant factor in explaining agility, followed by top management support. The
results also indicated that perceived usefulness has a strong effect on actual system
use. Similarly, the results also indicated that exogenous variables (independent
variables) influence actual system use, particularly system characteristics, job
characteristics and top management support. The results then revealed that actual
system use mediated the relationships between these exogenous variables and
agility. The findings have several implications for information system (IS)
management practice. Thus, implications for the acceptance of IT and agility, for
theory and practice that follow, and future research are also discussed. |
