Reuse throughout system life cycles is the most promising organizational policy for cost containment and benefit exploitation available to information system managers today. Large-scale reuse is an expensive endeavor whose benefits are realized when it is applied strategically rather than tactically. The distinction eludes many (and challenges most) IS managers. We present a reuse reference grid for managers to use as an assessment framework to help categorize and assess the cost/benefit of their current level of reuse as a prelude to considering future reuse opportunities.
