software engineering
subject			fact

software engineering	has definition The process of solving customers problems by the systematic development and evolution of large, high-quality software systems within cost, time and other constraints. The application of engineering to software systems of any kind
	has challenge accurately forecasting how much time it will take either to develop a system, or to make a specific set of changes
	has definition from the Canadian Standards Association The systematic activities involved in the design, implementation and testing of software to optimize its production and support
	has definition from the IEEE (1) The application of a systematic, disciplined, quantifiable approach to the development, operation, maintenance of software; that is, the application of engineering to software. (2) The study of approaches as in (1)
	has goal solving customers' problems
	has part ensuring that maintenance and evolution of software is done in a systematic way
	has part evolution
	has part maintenance
	has part managing software projects
	has part programming
	has part programming
	has part project management
	involves applying well-understood techniques in an organized and disciplined way
	involves the translation of higher-level designs into particular programming languages
	is / labour-intensive
	is highly iterative
	is undergoing development in its technology and techniques
	is a subtopic of 1.2 - What is Software Engineering?
	is normally organized into software projects
	is a kind of process
	sometimes consists of developing completely new software
	uses resources such as the time and money of the stakeholders, and the CPU-time and memory of computers
	usually consists of modifying software that has been already written - this is because software is normally continually changed over a period of years until it becomes obsolete

Kinds of software engineering :

• forward engineering (5 facts) - Moving from requirements to design or design to implementation
• reengineering (12 facts) - A type of maintenance performed to improve the design of some part of a software system, in general so that it has higher maintainability. In general, no new features are added for users
• refactoring (5 facts) - Changing part of the design; performed as part of reengineering
