Management of reuse at IBM [Technical forum]

For years, programmers have believed that productivity gains could be achieved if programs could be reused. The logic is that it is better to obtain code from libraries that contain reusable parts than to write new code. One can easily see the productivity gains from not writing code, as long as measurement of productivity is not made in the standard form of lines of code per unit of effort. Building systems from existing proven parts can also lead to increases in quality.
