Software Engineering:

Software engineering is an engineering discipline which is concerned with all aspects of software production. In this definition, there are two key phrases:

Engineering discipline: Engineers make things work. They apply theories, methods and tools where these are appropriate, but they use them selectively and always try to discover solutions to problems even when there are no applicable theories and methods. Engineers also recognize that they must work to organizational and financial constraints, so they look for solutions within these constraints.

All aspects of software production: Software engineering is not just concerned with the technical processes of software development but also with activities such as software project management and with the development of tools, methods and theories to support software production.
