reuse of applications
subject			fact

reuse of applications	involves taking complete applications and adapting them to the needs of the client by adding a small amount of extra software that makes the applications behave in special ways the client wants
	is a subtopic of 3.1 - Reuse: Building on the Work and Experience of Others
	is a kind of reuse
reuse	can occur if software developers reuse existing good-quality components, and also contribute to reusable components that others can use
	has purpose to reduce the large cost associated with developing the same thing over and over again
	has risks Poor quality reusable components Compatibility or availability not maintained
	is one of the keys to successful software development
	is not a strong part of the development culture of many organizations
	is not as extensive in software engineering projects as might be desirable
	may be prevented because of a vicious circle: Developers do not develop high quality reusable components, so there is nothing to reuse. Since there is nothing to reuse, software developers take so much time to develop applications that they lack time to invest in reusable frameworks or libraries
	may not be practised because developing anything reusable is seen as not directly benefiting the current customer If a developer has painstakingly developed a high-quality reusable component, but management only rewards the efforts of people who create the more visible 'final product', then that developer will be reluctant to spend time on reusable components in the future Efforts at creating reusable software are often done in a hurry and without enough attention to quality. People thus lose confidence in the resulting components, and in the concepts of reuse and reusability

Kinds of reuse of applications :

• reuse of commercial off-the-shelf software (3 facts)
