Software Engineering

The IEEE developed the following definition for software engineering: (1)The application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software; that is, the application of engineering to software. (2) the study of approaches as in (1). And yet, a "systematic, disciplined, and quantifiable" approach applied by one software team may be burdensome to another. We need discipline, but we also need adaptability and agility. Software engineering is a layered technology. Any engineering approach must rest on an organizational commitment to quality. Total quality management, Six Sigma, and similar philosophies foster a continuous process improvement culture, and it is this culture that ultimately leads to the development of increasingly more effective approaches to software engineering. The bedrock that supports software engineering is a quality focus. The foundation for software engineering is the process layer. The software engineering process is the glue that holds the technology layers together and enables rational and timely development of computer software. Process defines a framework that must be established for effective delivery of software engineering technology.

Quality Focus

The bedrock that supports software engineering is a __________.

C. Software requirements continually change, but change can be easily accommodated because software is flexible.

The reality "when requirements changes are requested early, the cost impact is relatively small" clarifies the myth "__________." A. If a firm decides to outsource the software project to a 3rd party, it can just relax and let that other firm build it.. B. Once we write the program and get it to work, out job is done. C. Software requirements continually change, but change can be easily accommodated because software is flexible. D. If we get behind schedule, we can add more programmers to catch up.

True

True or false: When software requirements changes are requested early, the cost impact is relatively small. However, as time passes, the cost impact grows rapidly.
