Final answer:
Stress and fatigue can have a significant impact on business process design, affecting employee performance, decision-making, problem-solving, and interpersonal relationships.
Step-by-step explanation:
Stress and fatigue are psychological factors that can affect business process design. The modern understanding of stress highlights that it can evoke various responses including physiological, cognitive, and behavioral changes.
A key concept is the curve of stress and performance, where a moderate level of stress (eustress) can enhance performance, but beyond an optimal point, excessive stress (distress) leads to a decrease in performance and can result in health issues such as job burnout and even contribute to serious physical illnesses.
Factors such as negative interactions, lack of emotional support, and supervisorial style can significantly influence employee stress levels, therefore, they must be considered in designing effective and healthy business processes.
