Let us first understand what software engineering stands for. The term is made of two words, software and engineering.
Software is more than just a program code. A program is an executable code, which serves some computational purpose. Software is considered to be collection of executable programming code, associated libraries and documentations. Software, when made for a specific requirement is called software product.
Engineering on the other hand, is all about developing products, using well-defined, scientific principles and methods.
Software engineering is an engineering branch associated with
development of software product using well-defined scientific
principles, methods and procedures. The outcome of software engineering
is an efficient and reliable software product.

IEEE defines software engineering as:(1) The application of a systematic,disciplined,quantifiable approach to the development,operation and maintenance of software; that is, the application of engineering to software.Fritz Bauer, a German computer scientist, defines software engineering as:
(2) The study of approaches as in the above statement.
Software engineering is the establishment and use of sound engineering principles in order to obtain economically software that is reliable and work efficiently on real machines.
