MA institutionalisation. All the aspects of MA institutionalisation examined in this study support this notion: large firms establish more MA departments, use more strategic MA and operational planning instruments, show higher levels of MA formalisation and employ more academically trained heads of MA than do medium-sized firms. Furthermore, our regression models show that firm size is the strongest predictor of the establishment of discrete MA departments and the number of strategic MA instruments used. However, from our data on large firms, there is no negative linear correlation between the level of family influence and MA institutionalisation. These results reconfirm the findings from German-speaking countries that large family businesses do not greatly differ from large non-family businesses regarding the usage of strategic and operational MA practices
