Few Definitions of Software Engineering

1. Software Engineering is an engineering discipline which is concerned with all aspects of software production.
2. Software engineering (SE) is the application of a systematic, disciplined, quantifiable approach to the design, development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering to software.
3. In Software Engineering we study how to build and maintain software systems in a controlled, predictable way. A good software engineering should give control over Functionality, Quality and Resources.
4. Software Engineering is a branch of computer science that creates practical, cost-effective solutions to computing and information processing problems, preferentially by applying scientific knowledge and developing software systems in the service of mankind.
