Most work on component or function based DSMs thus far starts with an assumption that decomposition is trivial. In this paper we introduce three distinct approaches to decomposing a complex system: assembly decomposition, functional decomposition and service based decomposition. Then we apply these guidelines to a Xerox printing system. We conclude that the results of architectural analysis, for a complex system, are directly affected by the approach taken to decompose the system and the whole to part ratio.

Keywords: System development, decomposition, system architecture, DSM, whole to part ratio
