Information Systems Development


This chapter more closely examines the systems development process that was first introduced in Chapter 1. Successful systems development is governed by some fundamental, underlying principles that we introduce in this chapter. We also introduce a basic, representative systems development methodology as a disciplined approach to developing information systems. Although such an approach will not guarantee success, it will greatly improve the chances of success. You will know that you understand information systems development when you can:



Describe the motivation for a standard systems development process in terms of the Capability Maturity Model (CMM) for quality management.

Differentiate between the system life cycle and a system development methodology.

Describe 10 basic principles of systems development.

Define problems, opportunities, and directives—the triggers for systems development projects.

Describe the PIECES framework for categorizing problems, opportunities, and directives.

Describe the essential phases of systems development. For each phase, describe its purpose, inputs, and outputs.

Describe cross life-cycle activities that overlap multiple system development phases.

Describe typical, alternative “routes” through the essential phases of systems development. Describe how routes may be combined or customized for different types of projects.
