Developing Business/IT Solutions

Chapter 12: Developing Business/IT Solutions introduces the traditional, prototyping, and end-user approaches to the development of information systems and discusses the processes and managerial issues in the implementation of

new business applications of information technology.

1. Use the systems development process outlined in this chapter and the model of IS components from 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 can be used as an effective technique to improve the process of systems development for end users and IS specialists.

4. Understand the basics of project management and their importance to a successful system development effort.

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

6. Compare and contrast the four basic system conversion strategies.

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

The Systems Development Cycle. Business end users and IS specialists may use a systems approach to help them develop information system solutions to meet business opportunities. This frequently involves a systems

development cycle where IS specialists and end users conceive, design, and implement business systems. The stages, activities, and products of the information systems development cycle are summarized in Figure 12.3.

Prototyping. Prototyping is a major alternative methodology to the traditional information systems development cycle. It includes the use of prototyping tools and methodologies, which promote an iterative, interactive process that develops prototypes of user interfaces and other information system components. See Figure 12.9.

End-User Development. The application development capabilities built into many end-user software packages have made it easier for end users to develop their own business applications. End users should focus their

development efforts on the system components of business processes that can benefit from the use of information technology, as summarized in Figure 12.14.
