Introduction to Information Systems

12 Developing Business/IT Solutions

I. CHAPTER OVERVIEW

This chapter introduces the traditional, prototyping, and end user approaches to the development of e-business systems, and discuss the processes and managerial issues in the implementation of new e-business systems and technologies. It presents a systematic approach to problem solving. It then introduces a variety of approaches used by IS professionals and end users to develop information system solutions to business problems.

II. LEARNING OBJECTIVES

Learning Objectives

1. Use the systems development process outlines in this chapter, and the model of IS components for Chapter 1 as problem-solving frameworks to help you propose information systems solutions to simple business problems.

2. Describe and give examples to illustrate how you might use each of the steps of the information systems development cycle to develop and implement a business information system.

3. Explain how prototyping improves the process of systems development for end users and IS specialists.

4. Identify the activities involved in the implementation of new information systems.

5. Describe several evaluation factors that should be considered in evaluating the acquisition of hardware, software, and IS services.

6. Identify several change management solutions for end user resistance to the implementation of new information systems.

III. TEACHING SUGGESTIONS

The basic steps of the systems approach should be related to the traditional Systems Development Cycle illustrated in Figure 12.3. It should be emphasized in the SDLC that the five steps of the cycle fit into the three stages of the traditional systems approach. The specific activities involved in each of the stages should be discussed at length. As well, it should be made clear to the students that the various stages are related and interdependent, and that the...
