PEAR+ Performance Influencing Factors Analysis Methodology
The PEAR+ Model is an evolution of the foundational PEAR framework (People, Environment, Actions, Resources), widely used in human factors engineering for safety-critical industries such as aviation. While the original PEAR model effectively addresses static, task-specific environments, PEAR+ expands its scope to account for the complexities of dynamic, technology-driven systems.
This enhanced model incorporates cognitive, interactional, and adaptive factors, integrates proactive system feedback, and addresses emerging challenges such as automation, virtual and augmented reality, cybersecurity, and hybrid operations. By focusing on decision-making under stress, team dynamics, and trust in automation, PEAR+ provides a forward-thinking approach applicable to all industries.
The addition of feedback loops and system-level integration shifts the focus from reactive risk mitigation to proactive error prevention and continuous improvement, ensuring resilience, adaptability, and inclusivity in complex human-system operations.
