Innovation contributes to firm performance. An important task of effective innovation management is to terminate poorly performing projects and reallocate their resources to other, more promising projects. Despite the challenges of such a task, some actors quickly terminate flawed projects while others persist. To investigate decisions about a project’s flaws, we build on theoretical insights from the voice literature to offer a model of voicing concerns over a project’s flaws based on the amount of information available to project team members. We test the model using 3,760 decisions nested within 235 project team members from the research and development (R&D) departments of large firms operating in innovative industries. We find that more information about a project’s flaw increases project team members’ willingness to voice concerns and that this positive effect is stronger for project team members who believe that they have more open-minded supervisors and who themselves are more prosocially motivated. This theorizing and set of findings provides new insights into our understanding of facilitating voice in organizations and managing innovation and entrepreneurial projects
