Software engineering (SE) is the application of a systematic, disciplined, and quantifiable approach to the development, operation, and maintenance of software and to the study of these approaches; that is, the application of engineering to software because it integrates mathematics, computer science, and meaningful practices whose origins are in engineering. Developing good software projects requires a proper process to be followed by the organization. This software process required to produce software differs from company to company.
