This paper compares the adoption and design of Computer-Aided Production Ma
nagement (CAPM) technologies in Sweden and the UK and examines the influenc
e of technology suppliers and Professional Associations (PAs) as central ag
encies in shaping this diffusion process. Members of professional operation
s management associations in each country were surveyed and interviews were
carried out with key stakeholders. These revealed differences in diffusion
patterns with earlier adoption of standardized packaged solutions in the U
K and a stronger reliance on in-house customized systems in Sweden. An expl
anation for this is that highly codified and portable nations of 'best prac
tice' have been promoted more strongly both by technology suppliers and PAs
in the UK than in Sweden. The paper suggests that objectified forms of kno
wledge communication and fashion setting have dominated diffusion and desig
n processes more heavily in the UK than in Sweden. This may be problematic
because objectified notions of 'best practice' under-emphasize the context-
sensitivity of the technology and the need for organizational redesign. It
is argued that the observed differences in the patterns of diffusion requir
e an explanation at the level of societal effects.
