This is thefirst study designed to systematically survey the acceptance of WBT in the construction industry, which was accomplished
by employing an extension of the TAM to investigate the determinants of acceptance of WBT on the part of construction professionals.
The results demonstrate that the proposed model successfully accounts for how construction professionals come to accept WBT. In
particular, it was found that user satisfaction is an adequate indicator
of acceptance of WBT in the construction industry, hence that to facilitate the acceptance of WBT, a construction firm should focus on the
satisfaction of its employees with WBT. It was also found that construction professionals' satisfaction with WBT was much more significantly affected by their belief about usefulness than by their belief
about ease of use, which suggests that use of WBT systems that
place greater emphasis on content quality are more likely to meet
with success than those that are—or give the impression of being—
easy to use. Finally, it was found that computer anxiety (a determinant of perceived usefulness) and organizational support (a determinant of perceived ease of use) are more important external variables
than enjoyment, social influence, information quality, and system
quality in terms of their effects on the acceptance of WBT. For the success of WBT in the construction industry, management should provide appropriate organizational support and help to alleviate
construction professionals' computer anxiety. At the organizational
level, computer anxiety could be managed by providing introductory
computer training to employees before forcing higher-level IS on
them
