The front-end customer–supplier collaborative creation processes are attracting increasing interest from project scholars. We still know little of these processes, however, which are increasingly being digitalized. Drawing from a qualitative case study of customer–supplier knowledge collaboration (KC) at the front-end phase of oil and gas projects in Norway, we explore why collaborative actors struggle to achieve KC openness in the digital age. We develop a model displaying how the fragmented ambient awareness networks and the coexisting collaborative and digital logics exacerbate the subjectivity of the project actors, giving rise to sharing–protection tensions. We offer novel insights for project management and interorganizational relations literature by showing how logic complexity challenges the project organizations’ inherent efforts to achieve open, digitally driven KC at the projects’ front end. Our results also suggest that logic complexity and double talk around KC showcase a hypocritic organizational response to the enduring openness challenge in customer–supplier project relations in the digital age.
