Costs and benefits of reuse

Reuse will increase the quality of our computer systems and staff reproductivity during development and maintenance phases. Reuse does not occur for free - we must manage the costs of creation, usage and support, along with changing our practices so that reuse is not just part of an utopian vision but a day to day activity throughout the development process. Measurement of reuse levels, staff trained and/or specialising in reuse, software support for the process of reuse and economic models to justify reuse are a few tools available in breaking down the barriers to reuse.
