EMERGING OF SOFTWARE ENGINEERING:

The computers have been for commercial purpose. With easy aspect of computer development, software engineering has been tasked to solve larger and complex programs and in a cost effective and efficient manner. Also the development and maintenance of the software product has become and important criteria. In early years, engineering faced many problem without having a better knowledge in this field, such as late delivery of the software, development team exceeding the budget, poor quality, user requirement are not completed supported by the software, difficult maintenance and unreliable software and lack of systematic approach. Thus number of large size project failed, called soft ware runaway result in software crisis. Thus, emerges the software engineering principles.
