Systems analysis and design: In a changing world/ John W. Satzinger, Robert B. Jackson, and Stephen D. Burd. 4th ed. Singapore; Course Technology., 2007. xxxii, 672 p.; 25 cm. ill. Includes indexes. The focus of this chapter is on new techniques that are advancing the way systems are being developed. The chapter begins by reviewing five important principles in software development: abstraction, models and modeling, patterns, reuse, and methodologies. Together, these principles form the foundation on which object-oriented development is based. System developers are using these principles to devise new, unique approaches to developing systems. One of the most active trends in software development is adaptive development methodologies. The unified process (UP) is an example of an adaptive methodology that is also influencing many more radical approaches. The idea behind adaptive methodologies is that software projects need to be agile, or flexible, because the business world is unpredictable and changes so rapidly. Systems And Analysis Design.
