Definition
Reusability describes the degree to which the application and the
code in the application have been specifically designed, developed,
and supported to be usable in other applications.
Score
| Score As |
Descriptions To Determine Degree of Influence |
| 0 |
No reusable code. |
| 1 |
Reusable code is used within the application. |
| 2 |
Less than 10% of the application code developed is
intended for use in more than one application. |
| 3 |
Ten percent (10%) or more of the application code
developed is intended for use in more than one application.
|
| 4 |
The application was specifically packaged and/or
documented to ease reuse, and the application is customized at
the source code level. |
| 5 |
The application was specifically packaged and/or
documented to ease reuse, and the application is customized for
use by means of user parameter maintenance. |
Hints
- A score of 1 is awarded for reusing code regardless of where
it was developed.
- Code developed specifically for reuse within the application
and used more than once within the application counts as well as
code retrieved from a central library and available for general
use
- To score 2 or more, the code must be developed for use in more
then one application, stored and managed in a central library and
be available for general use. Code from one application that is
cut and pasted into another application is not considered reuse.
- The reusable code would be supported by documentation that
enables and eases the reuse.
- Examples of applications customized through use of parameters
include PeopleSoft and SAP and would generally receive a score of
5.
- Reused code may be slightly modified in the receiving
application.
- Examples of reuse include objects or other static code
maintained in an object/code library.
Typically
Scoring is not platform dependent.
