facilitate access to corporate information, personal
data, transactions and services.
In organizations used to more traditional modes of
exchange, the introduction of a B2E e-commerce
model represents the passage to a virtual mode of
exchange. According to Rahim (2007), despite the
considerable business value of the B2E portal,
acceptance remains a challenge, and numerous
issues need to be addressed before such a system can
be implemented. These include personal factors
(such as perceptions of the portal as having limited
usefulness), organizational factors (the availability
of dedicated resources, support from management,
etc.) and employee awareness. It is our belief that
securing corporate commitment and dedicated
resources for the system and centralizing its
management will help ensure its sustainability.
In this context, the development of a B2E model is
supported by the TAM (Technology Acceptance
Model). The TAM is an information systems theory
that models how users accept and use technology
(Davis et al., 1989). Originating in socio-
psychological behaviourist models—i.e. the theories
of reasoned action and planned behaviour—the
TAM posits that the actual use of an information
system is contingent upon the user’s intent to use it.
This intent hinges on two factors: the technology’s
perceived usefulness (PU), and its perceived ease-of-
use (PEOU). These two constructs are in turn
influenced by external variables such as the product
characteristics or the training provided.
Davis (1989) defines perceived usefulness as the
degree to which a person believes that using a
particular system will enhance his or her job
performance. PU is a major factor in determining
system use, and in some studies is directly linked to
the adoption of information technology systems.
Figure 1: The Technology Acceptance Model (TAM).
As regards e-commerce, Davis (1989) defines PU as
the degree to which an individual believes that
carrying out the transaction online will increase the
effectiveness of his or her action. Davis also defines
PEOU as the degree to which a person believes that
using a particular system will be relatively effort-
free. This is a secondary factor that directly affects
the adoption of a given technology, although
conclusions are still pending as to its impact on the
use of information technology systems (Shih, 2004).
4 THE B2E MODEL
We developed the following B2E model as an
electronic platform solution inspired by the specific
needs of our health care context: being in a
university health care network; the need to address
health care system performance; being in a
competitive environment for health care human
resources; and having to respond to ongoing health
care transformation in terms of knowledge
management and information sharing. The system’s
functions meet the following objectives, namely,
fostering collaborative exchanges, competence
management, time management, learning
management and communication.

5 CREATING A B2E TOOL: MY
PORTAL
The My Portal initiative originated in the Nursing
Informatics department. The need to share
information and transfer knowledge among
professionals and between departments was
perceived as a key factor in attempting to create
interprofessional networks and break down the silos
within the organization. My Portal was also
designed as a B2E tool that would provide all health
care workers with an easy and accessible means of
creating, sharing and applying knowledge and
information.
When using My Portal, employees can navigate
between the following sections: 1) corporate
(MUHC) affairs, 2) a toolbox, 3) a forum, 4)
