Project forms of organizing are theorized to rely upon horizontal as opposed to vertical lines of authority, but few have examined how this shift affects progression---how people advance in an organization. We argue that progression without hierarchy unfolds when people assume lateral authority over project tasks without managing people. With a longitudinal study of a mature, collectively managed open source software project, we predict the individual behaviors that enable progression to lateral authority roles at two different stages. Although technical contributions are initially important, coordination work is more critical at a subsequent stage. We then explore how lateral authority roles affect subsequent behavior---after gaining authority, individuals spend significantly more time coordinating project work. Our research shows how people progress to the center as opposed to up a hierarchy, and how progression differs by stage and specifies the theoretical relationship between lateral authority roles and the coordination of project work.

Arecognized challenge in innovation scholarship is how to coordinate the efforts of many minds contributing to the design of a single artifact. Much research shows that product concept representations can help coordinate design tasks, but we know little about the practices that make representations more or less effective. We used an inductive approach to examine how six teams in three industries used concept representations when creating novel products. All six teams crafted three types of representations: stories, metaphors, and prototypes. However, merely using representations did not ensure a shared repertoire and concept coherence—a common understanding of desired product attributes. Teams that failed to consistently engage in three practices—(1) collective scrutiny of representations, (2) linking representations to design constraints, and (3) active editing of representations—produced concept disunity, with disparate understandings of desired product attributes. Teams that maintained concept coherence were better able to coordinate design tasks than teams that experienced concept disunity. Our research explains how the ultimate effect of concept representations on the coordination of innovation is contingent on the practices used to manage a repertoire of representations in use.

The ‘variance hypothesis’ predicts that external search breadth will lead to innovation outcomes, but time for search is fixed and cultivating breadth takes time. How does individuals’ external search breadth affect innovation outcomes? We match survey data with complete patent records, to examine the search behaviors of elite experts at one of the world’s most innovative firms. Counter to expectations, individuals who spent more time inside the firm were more likely to be innovative. Individuals with high external search breadth were more innovative only when they allocated more attention to those sources. Our research identifies limits to the ‘variance hypothesis’ and reveals two successful approaches to innovation search: ‘cosmopolitans’ who cultivate and attend to external sources and ‘locals’ who draw upon internal sources.

Scholars have studied how entrepreneurs acquire resources but have not examined how resources may be bundled with constraints, which can threaten entrepreneurial autonomy. Organizational sponsors, such as incubators and accelerators, provide entrepreneurs with resources, but how do entrepreneurs sustain autonomy while seeking resources and support? We studied five entrepreneurial firms in a business incubator over a six-month period. While benefiting from incubator resources, entrepreneurs also experienced unexpected constraints, including mentor role conflict, gatekeeper control, and affiliation dissonance. By showing how entrepreneurs unbundled the incubator’s resources from constraints, we explain how entrepreneurs manage the tension between acquiring resources and preserving autonomy.
