Collaborative relationships between firms have been growing in importa
nce, including 'partnerships' between customers and suppliers. Institu
tional economists and sociologists have different views on the origins
, character and consequences of partnership, and the nature of this de
bate is outlined, as well as the implications for the reality of 'part
nership' and its role in the diffusion of business practice. Against t
his background we use case study and survey evidence to explore the tr
ansition within the supply chain relationship, from a customer 'demand
s' model and hence to 'supplier development'. Supplier development can
be seen as an aid to risk reduction, particularly where it involves m
anagement control system development in the supply organization. The p
artnership implications for the human resource management (HRM) functi
on are explored. Supply-side partners are likely to be involved increa
singly with activities that will underpin the alliance (for example, t
raining, cultural change and removal of industrial relations obstacles
to change). These indirect effects may be supplemented by direct invo
lvement by the HRM specialists in the customer organization, especiall
y where partnership development places strong reliance on the human re
source dimensions of the two organizations. Examples of this form of d
evelopment are discussed. This evidence is assessed in terms of the di
fferent disciplinary approaches discussed at the outset. What emerges
most strongly is that although 'partnership' is used to describe many
inter-firm relationships, many of these are very unequal and are recog
nized to be so, but in other cases evolutionary steps can be taken to
reduce the risks involved and lead to apparently equitable alliances.
Within this risk reduction process, the role of human resources appear
s to be of varying importance.
