4 of the hoai 2013, Reused components
are to be credited accordingly.
SCADE System provides a comprehensive environment and user-friendly interface that simplifies systems engineering tasks that are otherwise complex to handle: consistent replication of reused components
in a system architecture, propagation within the architecture of data imported from pre-existing databases and generation of up-to-date and consistent ICDs.
Such a repository should have the ability to track the content pieces, assemble them into deliverables (sometimes called XML instances), track various versions of the content, manage the linkages of reused components
, and maintain a detailed history of all deliverables in the system.
When reused components do not have reused elements in common, we expect Reuse to be additive (property, Size.3).
We show later that slightly modified and verbatim reused components are quite similar from the point of view of defect density and rework.
This form is also used to capture whether the component has been developed from scratch or from a reused component. In the latter case, we collected the amount of modification - none, small, or large - needed to meet the system requirements and design, as well as the name of the reused component.
The net effect of reusing software is the same as for hardware: (1) greatly reduced development time, (2) greatly reduced development cost, and (3) increased reliability because the reused components have already been "shaken down."
Some entries on the list correspond to custom product-specific parts (i.e., new software), while others correspond to reused components or customized reused components.
* an agreement to replace one reused component with another results in SCM making the corresponding change to the parts list.
* an agreement to customize a reused component causes the development organization to create a new delta of custom code, and SCM to place the new software under control and to add it to the product's parts list.
Project managers were awarded budget increments and promotions when their deliverables were considered to have a large percentage of reused components
. A promotion and awards program was also established for systems developers (i.e., reusers).
