Earlier research showed through an empirical study of 60 US manufacturing companies that manufacturing proactiveness especially through investments in structural programs coupled with either high levels of manufacturing involvement or planned investments in infrastructural programs correlate with higher than average performance. To test and report if the same perception and practices are found in a developing country, here the same study is conducted in the developing country of Thailand. The results from 49 companies studied were mixed. They have not supported the findings in the developed country. Further analysis showed, in some cases, the findings are contradictory to prior results.
