Team members with well-defined roles contribute significantly to project success because clearly defined roles establish accountability and expectations among team members. When each team member knows their responsibilities and how they fit into the larger project, it fosters better collaboration, minimizes confusion, and enhances productivity. It allows for efficient communication and coordination, as team members can directly address issues and tasks within their areas of responsibility without overlapping into others’ domains unnecessarily.

Furthermore, having well-defined roles helps in leveraging each member's strengths and expertise, leading to improved performance and outcomes. This structure ensures that all necessary tasks are covered and that resources are allocated properly, which is essential for maintaining project schedules and quality.

While the other factors like a detailed organization chart and detailed specifications play roles in project management, they depend on the effective execution by team members who understand their roles. Similarly, having a full-time project manager can provide leadership and direction, but without a cohesive team where roles are clearly defined, the project may still struggle to succeed.
