Dr. Akhlas Ahmed
Preston University
Lecture # 08

2.  Use the systems development process
outlined and the model of IS components as
problem-solving frameworks to help you
propose information systems solutions to
simple business problems.
 Describe and give examples to illustrate how
you might use each of the steps of the
information system development cycle to
develop and implement an e-business
system.

3.  Explain how prototyping improves the process of
systems development for end users and IS
specialists.
 Identify the activities involved in the
implementation of new information systems.
 Describe several evaluation factors that should be
considered in evaluating the acquisition of
hardware, software, and IS services.
 Identify several change management solutions for
end user resistance to the implementation of new
e-business applications.

17. • Business professionals and IS specialists
use a systems approach to help them
develop information system solutions to
meet e-business needs.
• Prototyping is a major alternative
methodology to the traditional
information system development cycle. It
includes the use of prototyping tools and
methodologies, which promote an
iterative, interactive process.

18. • The application development capabilities built
into many end user software packages have
made it easier for end users to develop their
own e-business applications.
• The implementation process for IS projects
involves acquisition, testing, documentation,
training, installation, and conversion.
• Business professionals should know how to
evaluate IT products for acquisition. IT vendor
proposals should be based on specifications
developed during the design phase.

19. • Implementation activities include
managing the introduction and
implementation of changes in the
business processes, organizational
structures, job assignments, and work
relationships resulting from e-business
initiatives.
