The term software engineering begans in the 1960s. Writing software has envolved into a profession concerned with how best to maximize the quality of software and how to create it.Emergence as a profesion: by the early 1980s, to stand beside computer science and traditional engineering. In the software crisis of the 1960s, 1970s and 1980s, which identified many problems of software development. many of the projects ran over budget and schedule, a buch of project caused loss of life.The software crisis has been fading from view, because it is psychologically extremely difficult to remain in crisis mode for a protracted period.
Solving the software crisis was paramount to researchers and companies producing software tools.the cost of owning and maitaining software in the 1980s was trwice as expensive as developing the software. The rise of the internet led to very rapid growth in the demand for international information display/e-mail systems on the World Wide Web.
With the expanding demand for software in many smaller organizations, the need for inexpensive software solutions led to the growth of simpler, faster methodologies that developed running software, from requirements to deployment, quicker & easier. Software engineering is a young discipline, and is still developing.
