Factor scores of the research variables were analyzed using t-tests to assess the affects of process as a source of competitive advantage, purchasing involvement, and supplier involvement on process development/improvement practice and strategy. Contingency table analysis with the chi-square statistic was used to assess the affects of industry category.
