Corporate Innovation Culture and Dimensions of Project Portfolio Success: The Moderating Role of National Culture

This study examines the relationships between corporate innovation culture (analysis/practices) and dimensions of project portfolio success (strategic fit/portfolio balance) as well as national‐level culture practices as moderators. Data (N = 165) were collected in four countries differing in cultural practices. Analysis and practices were identified as positive, significant, and complementary predictors of both dimensions. As hypothesized, the corporate variables related more strongly and positively to the success dimensions when assertiveness was high rather than low. The findings, thus, suggest that corporate factors should be compatible with national culture to elevate the fit and balance of project portfolios.
