Provan and Sebastian (1998) question the relationship between
network integration and network performance and show that densely integrated networks
do not necessary achieve good performances, unless they can count on the
presence of strongly integrated and overlapping subgroups (clique overlap) to provide
services within it, thus leading one to suppose that multicentrally integrated network
structures (or networks strongly integrated in a number of overlapping subgroups) have
a positive effect on network performance
