Component Reusability |
| Reusability is an important characteristic of a high-quality software component.
A software component should be designed and implemented so that it can be reused in
many different programs. Component Reusability is about building a library of
frequently used components, thus allowing new programs to be assembled quickly from
existing components. |
| Component Reusability has produced greater schedule and effort savings than any
other
best practice.
We have applied this concept not only to the code, but also to the design, data,
documentation, test materials, specifications, and plan. We have created a repository
named Component Repository to store the components that are identified as commonly
used components. Currently this repository stores more than 100 reusable components.
The repository has a search feature to look for similar components. The repository
is managed by the Reuse Group, which has members from the design as well as
development
team.
This is a part of our long-term strategy. |
How it Works: |
| During the high-level design phase, a project gets divided into components. These
components get divided into various sub-components. For each of these components/
sub-components, a decision is made on whether to develop it from scratch or take a
similar component from the Component Repository and use it with a few changes. The
designer sometimes also recommends that a component should be developed in such a way
that it becomes part of the Component Repository. |
