In this article we study the way the quality of leadership, human resource
(HR) systems, manufacturing system and company performance are related and
whether this relationship is dependent upon a specific business culture. Us
ing data from UK, representing one culture, and Australia and New Zealand r
epresenting another, we have indicated that a universal structure between t
he mentioned four business components exists and that this structure is ind
ependent of the cultural setting within the areas we have chosen for this s
tudy. The main hypothesis is that the quality of leadership is unconditiona
l, while the probability of both a high-quality HR system and a high-qualit
y manufacturing system is conditional upon leadership quality. Finally, the
level of performance is conditional upon the joint effect of the quality o
f the HR system and the quality of the manufacturing system. This hypothesi
s is clearly supported by the data and, furthermore, data support that the
structure is independent of country. These conclusions mean, as we have als
o seen from a number of other studies that the choice of leadership style i
s crucial to the success of business operations and, hence, to the ultimate
performance of the company.
