Although no hypotheses were proposed for the direct
effects of OC and MC on project performance, the results
will be briefly reported. First, the test of the initial research
model without the mediator variable INN indicates direct
effects of OC on performance in exploratory (ˇ = 0.240,
p < 0.05) and exploitative innovation (ˇ = 0.326, p < 0.01),
but non-significant effects of MC (ˇ = 0.104, p > 0.05 and
ˇ =
−0.010, p > 0.05, respectively)
