The TAM uses two variables, perceived usefulness
and perceived ease of use, as determinants of
use.
The perceived usefulness is based on the
observation that “people tend to use or not use
the application to the extent they believe it will
help them perform their job better” (Davis,
1989). Even if an application is perceived as
useful, it will only be used if it is perceived as
easy to use, that is, benefits of usage outweigh
the effort of using the system. These two determinants
result in the user’s attitude toward
using the software system, which in turn leads
to the user’s behavioral intention to use. The
result is use of the system, a construct in the
DeLone-McLean success model.
Lee, Kozar, and Larsen (2003) summarize
research studies of the TAM, including studies
of 21 external variables affecting the model.
Neither training nor training satisfaction are
not included among these variables.
Our study examines the impact of training
on the TAM model. We also the examine impact
of personal characteristics on perceived ERP
training satisfaction and perceived usefulness
of the ERP systems. The proposed model is
shown in Figure 2.

Buchner (1999) argues that whatever your
choice of software, ERP should allow you to
integrate your existing business applications and
data libraries to make migration for users easy,
avoid downtime due to training, and reduce the
costs associated with migrating data. Schaaf(1999) found that ERP systems create important
implications for training. PeopleSoft (now a
division of Oracle) launched a satellite-based
system for delivering live training to hundreds
or even thousands of workers at companies
that buy its ERP applications (Spacenet, 2006;
Stedman, 1999), emphasizing the importance of training.
