SOFTWARE TESTING AND QUALITY ASSURANCE

SOFTWARE TESTING AND QUALITY ASSURANCE :

People seek quality in every man-made artifact. Certainly, the concept of quality did not originate with software systems. Rather, the quality concept is likely to be as old as human endeavor to mass produce artifacts and objects of large size. In the past couple of decades a quality revolution, has been spreading fast throughout the world with the explosion of the Internet. SOFTWARE TESTING AND QUALITY ASSURANCE

Global competition, outsourcing, off-shoring, and increasing customer expectations have brought the concept of quality to the forefront. Developing quality products on tighter schedules is critical for a company
to be successful in the new global economy. Traditionally, efforts to improve quality have centered around the end of the product development cycle by emphasizing the detection and correction of defects. Problem-Solving

On the contrary, the new approach to enhancing quality encompasses all phases of a product development process—from a requirements analysis to the final delivery of the product to the customer. Every step in the development process must be performed to the highest possible standard.

An effective quality process must focus on [1]:

What is Software Quality Assurance (SQA): A Guide for Beginners

A quality movement started in Japan during the 1940s and the 1950s by
William Edwards Deming, Joseph M. Juran, and Kaoru Ishikawa. In circa 1947, W. Edwards Deming “visited India as well, then continued on to Japan, where he had been asked to join a statistical mission responsible for planning the 1951 Japanese census” [2], p. 8. During his said visit to Japan, Deming invited statisticians for a dinner meeting and told them how important they were and what they could do for Japan [3].

In March 1950, he returned to Japan at the invitation of Managing Director Kenichi Koyanagi of the Union of Japanese Scientists and Engineers (JUSE) to teach a course to Japanese researchers, workers, executives,
and engineers on statistical quality control (SQC) methods. Statistical quality control is a discipline based on measurements and statistics. Decisions are made and plans are developed based on the collection and evaluation of actual data in the form of metrics, rather than intuition and experience. SOFTWARE TESTING AND QUALITY ASSURANCE

The SQC methods use seven basic quality management tools: Pareto analysis, cause-and-effect diagram, flow chart, trend chart, histogram, scatter diagram, and control chart [2]. In July 1950, Deming gave an eight-day seminar based on the Shewhart methods of statistical quality control [4, 5] for Japanese engineers and executives. He introduced the plan–do–check–act (PDCA) cycle in the seminar, which he called the Shewhart cycle (Figure 1.1). The Shewhart cycle illustrates the following activity sequence: setting goals, assigning them to measurable milestones, and assessing
the progress against those milestones. SOFTWARE TESTING AND QUALITY ASSURANCEINTERNAL COMBUSTION ENGINE

Deming’s 1950 lecture notes formed the basis for a series of seminars on SQC methods sponsored by the JUSE and provided the criteria for Japan’s famed Deming Prize. Deming’s work has stimulated several different kinds of industries, such as those for radios, transistors, cameras, binoculars,
sewing machines, and automobiles.
