Chapter 10 Developing E-Business Solutions

After reading and studying this chapter, you should be able to:

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 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.


Chapter Summary


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 10.3.

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 10.4.

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 10.16.

Implementing IS. The implementation process for information system projects is summarized in Figure 10.30. Implementation involves acquisition, testing, documentation, training, installation, and conversion activities that transform a newly designed business system into an operational system for end users.

Evaluating Hardware, Software, and Services. Business professionals should know how to evaluate the acquisition of information system resources. IT vendors' proposals should be based on specifications developed during the design stage of systems development. A formal evaluation process reduces the possibility of incorrect or unnecessary purchases of hardware or software. Several major evaluation factors, summarized in Figures 10.23, 10.24, and 10.25, can be used to evaluate hardware, software, and IS services.

Implementing Business Change. Implementation activities include managing the introduction and implementation of changes in business processes, organizational structures, job assignments, and work relationships resulting from business/IT strategies and applications such as e-business initiatives, reengineering projects, supply chain alliances, and the introduction of new technologies. Companies use change management tactics such as user involvement in business/IT planning and systems development to reduce and user resistance and maximize acceptance of business changes by all stakeholders.
