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 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.
