What is software engineering?
Software engineering is an engineering discipline which is concerned with all aspects of software production from the early stages of system specification through to maintaining the system after it has gone into use. In this definition, there are two key phrases:
1. ‘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 to support them. Engineers also recognize that they must work to organizational and financial constraints, so they look for solutions within these constraints.
2. ‘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 soft production.
In general, software engineers adopt a systematic and organized approach to their work as this is often the most effective way to produce high-quality software. However, engineering is all about selecting the most appropriate method for a set of circumstances and a more creative, informal approach to development may be effective in some circumstances. Informal development is particularly appropriate for the development of web-based e-commerce systems which requires a blend of software and graphical design skills. |
