Engineering Analysis of Democratic Leadership Impact on Team Performance under Different Stress Levels

Democratic leadership is widely promoted in engineering education due to its potential to enhance participation, communication, and ethical reasoning. However, its effectiveness under stressful, time-constrained conditions remains insufficiently explored. This study investigates the impact of democratic leadership on team performance among Mechanical Engineering students under varying stress levels. A quasi-experimental case study was conducted involving ten Mechanical Engineering students divided into two democratically led teams. The teams completed three tasks of increasing complexity: a cognitive task, a collaboration-intensive task, and an ethical decision-making scenario. Performance was evaluated using task accuracy, completion time, and response quality, while team dynamics were assessed through a post-task survey. Results show that 70% of participants reported improved communication, 60% reported enhanced problem-solving, and 60% expressed satisfaction with team performance under stress. However, findings also indicate that unstructured participation may delay decision-making. The study concludes that democratic leadership is most effective when combined with clear role assignment and structured task management in engineering teams.
