Despite the fact that firms and individuals have been sourcing on a
global basis since ancient times, global sourcing as a topic has
received considerable attention from managers and scholars in recent
years. Global business has been reported to be growing considerably
during the last decades and the trend continues; hence a scientific
examination of global sourcing performance and success factors is timely
and appropriate. This dissertation explores some of the effects, the
success factors, as well as the threats of global sourcing. Particular
attention is paid to performance evaluation and integration as a
prerequisite for successful global sourcing. It consists of four
independent scientific papers connected by means of a coherent
thematical bracket. The first two papers address the perception of
global sourcing as a purchasing panacea, and compare it to real results
from global sourcing. The last two chapters explore the role of the
buying companies' internal and external integration with suppliers,
giving insight into performance results from integration. The research
was performed with a triangulation of methods, notably findings from
qualitative and quantitative research, based on primary and secondary
data.
