Significance of S/W Quality Assurance in SDLC : A Review

Abstract

Quality is the main focus of any software engineering project. Without measuring, we cannot be sure of the level of quality in software. So the methods of measuring the quality are software testing techniques. This thesis report relates various types of testing technique that we can apply in measuring various quality attributes. Software development and maintenance is used to make the error-free Software and also concentrate on time-consuming and complex activity. To evaluate the quality of a software product and to keep its level high is much more difficult than to do them for the other industrial products. For maintaining the quality, performance, speed, efficiency and cost of the software the Software quality Assurance activities, principles and its methods are implemented in the early stages of software engineering development phases. The purpose of testing can be quality assurance, verification, and validation or reliability estimation. It is a tradeoff between budget, time and quality. Software Quality is the central concern of software engineering. Testing is the single most widely used approach to ensuring software quality.
