 Conclusion

3. Software reuse is the process of implementing or
updating software systems using existing software
assets.
 The systematic development of reusable components.
 The systematic reuse of these components as building
blocks to create new system.

4.  Increase software productivity
 Shorten software development time
 Improve software system interoperability
 Develop software with fewer people
 Move personnel more easily from project to project
 Reduce software development and maintenance costs
 Produce more standardized software
 Produce better quality software and provide a powerful
competitive advantage

5.  Application system
 Subsystem
 Component
 Module
 Object
 Function or Procedure

6.  Horizontal Reuse: Horizontal reuse to software
components used across a wide variety of
applications.
 Vertical Reuse: the reuse of system functional
areas, or domains, that can be used by a family of
systems with similar functionality .

7.  Identify domain
 Identify and classify reusable abstractions
 Identify design/programming language constructs that
support reuse
 Study and formulate language reuse guidelines
 Study and formulate domain reuse guidelines
 Reuse assessment- assess components based on the
guidelines
 Reuse improvement- modify and improve these
components.

8.  Component management tools, such as
repositories, designs, documentation, and code
must be developed and maintained
 Domain analysis tools and procedures for the
development and maintenance of a domain
architecture

9.  The principles, methods, and skills required to develop
reusable software cannot be learned effectively by
generalities and platitudes.
 To succeed in-the-large, reuse efforts must address both
technical and non-technical issues.

10. Software reuse is proved to be an efficient way to
help improving software development quality,
productivity during all these years’ practices.
Although it is not perfect, but is still worthy more
research effort.
