This paper discusses implementation of Eisner's Developer Off-the-Shelf Systems (DOTSS) system acquisition approach. The DOTSS method involves reuse of entire systems rather than reuse of modules or subsystems. Reuse issues, including methods, benefits, and obstacles as they relate to the DOTSS approach, are presented. The use of Domain Analysis is proposed as a means of developing a set of high-level system requirements that are not overly specific to the problem domain at hand, thereby allowing existing systems from related domains to be considered for reuse. A set of evaluation criteria that can be used to differentiate candidate systems is also included.
