Overview of the OSSAD Methodology
The Office Support System Analysis and Design (OSSAD) methodology was developed to guide the analysis and design of office organizations and office support systems (OSS) ((Conrath and Dumas, 1989). A new methodology was needed because earlier system design methodologies emphasized technical aspects and ignored the organizational problems in an office environment (Leppänen and Savolainen 1988, Leppänen and Savolainen 1989). The problems of the earlier approaches were numerous (Friedman, 1997, Marcus and Robey, 1988, Schaefer 1988, pp. 40–43, 169–171). The OSSAD project in the ESPRIT Programme was supported by researchers from France, Germany, Canada, Italy, and Finland. During its development it was field-tested and applied in all these countries. This chapter gives a brief overview of this methodology and summarizes the OSSAD Manual (Conrath and Dumas, 1989).
