(2001). It is noted by Bhattacherjee (2001) that
perceived usefulness is based on others' opinions
or information proposed through mass media in
the acceptance stage, while perceived usefulness
in post-acceptance stage is formed through users
first-hand experience and is, therefore, more re-
liable. As such, Perceived Usefulness is the key
factor that motivates users' intention to continue
using a system in the future (Bhattacherjee &
Sanford, 2006). When users believe that ERP
can enhance the productivity and efficiency of
their work, they tend to develop positive attitude
toward the system and consider the use of ERP
as a beneficial and useful (Chen & Chien, 2009).
Based on the above discussion, the following
hypothesis is proposed:
ERP were measured using three items derived from
Bhattacherjee (2001). While perceived usefulness
and satisfaction derived from Zvirian et al. (2005).
Subjective norm and perceived behavior control
derived from Taylor and Todd (1995). All scales
used five-point Likert scales anchored between
“strongly disagree” (1) to “strongly agree” (5)
with “uncertain” (3) except satisfaction anchored
from “almost never” (1) to “almost always” (5)
with “about half of the time” (3). Please refer to
the appendix of this chapter for a full version of
the instrument.
The demographic and other data included
information about the respondent's gender, age
and years of using ERP system in his/her current
organization. In addition to his/her current posi-
tion, the kind of industry and the kind of ERP
system he/she is using.
The data was collected through online question-
naire on Survey Monkey website. We collected
the data for a whole month by forwarding the
link of the questionnaire to the companies imple-
mented any kind of ERP, either international ERP
(Oracle, SAP, Microsoft, and Focus) or local ERP
(ALMOTAKAMEL). The companies, we have
chosen, implemented ERP at least for one year.
H5a:
In an ERP implementation environment
Perceived Usefulness has a positive effect on
Users' Intention to continue using ERP system.
H5b:
In an ERP implementation environment
Perceived Usefulness has a positive effect on
satisfaction of using ERP system.
We summarize the proposed relationship to be
tested in this research in (Figure 1).

reseArch MethodoLogY
A total of 223 responses were obtained from the
companies in Egypt. Some demographics were
collected and the analysis of which is presented
in the following figures. (Figure 2), gender dis-
tribution is presented showing great percentage
of male users of ERP.
(Figure 3) presents the ERP systems surveyed
in our research study. The results show that the
majority of users are using Oracle ERP with next
level using SAP and Microsoft while the group
of users utilizing local (ALMOTAKAMEL) and
emerging Indian ERP (Focus) is still in its infancy.
The industries represented in the study are
reasonably versatile reflecting different interests
survey
Data was collected through online questionnaire
from Egyptian companies using ERP systems.
Online survey has the advantages of speeding up
large amount of data collection and allowing for
electronic data entry (Parasuraman & Zinkhan,
2002). The unit of analysis is end-users of an ERP
system within organizations. Participation in this
study was voluntary.
All used instruments had been validated by
prior studies. These instruments were modified
for the adaptation to ERP usage. The scales of
confirmation and users' intention to continue using
