“Reuse [software] engineering is a process where a technology asset is designed and developed following architectural principles, and with the intent of being reused in the future” (Bean, 1999). “If programming has a Holy Grail, wide-spread code reuse is it with a silver bullet. While IT has made and continues to make laudable progress in our reuse, we never seem to make great strides in this area” (Grinzo, 1998). “The quest for that Holy Grail has taken many developers over many years down unproductive paths” (Bowen, 1997). This article is an overview of software reuse methods, particularly object oriented, that have been found effective in business systems over the years.
