Fostering the inclusion of vulnerable members is particularly important in team-based workplace environments, where collaboration and collective engagement are crucial for success. However, vulnerable team members may face unique challenges, necessitating a structured approach to identifying and providing them with the appropriate support. This study seeks to identify team members who may require additional support and to determine the most suitable individuals within the team to act as supporters, thereby optimizing overall team contributions. We aim to foster enhanced collaboration and ensure more effective teamwork by evaluating each member’s performance in detail. Employing Interval Data Envelopment Analysis (Interval DEA), we establish efficiency intervals encompassing a range of possible efficiency values from multiple perspectives. This methodology ensures that all team members are actively contributing. This approach aligns directly with Goal 8 of the Sustainable Development Goals (SDGs), which emphasizes inclusive economic growth and the promotion of decent work for all. By fostering inclusive participation within teams, we contribute to the broader objectives of sustainable development, ensuring that every team member can reach their full potential and that team performance is maximized through collective effort. This methodology enhances individual contributions and strengthens overall team cohesion and performance.
