Validation and the human element

Area of Science:

• Process Engineering
• Risk Management
• Validation Sciences

Background:

• Human intervention points are frequently the weakest links in process operations.
• The intrinsic error rate of manual operations and flawed process design contribute to process risks.
• Validation studies often overlook the human element, focusing primarily on mechanical and technological aspects.

Purpose of the Study:

• To analyze risks associated with human intervention in processes.
• To demonstrate the application of Failure Mode Effect Analysis (FMEA) and Process Reengineering in identifying human-related risks.
• To discuss the implications for training and qualification within the validation context.

Main Methods:

• Utilized Failure Mode Effect Analysis (FMEA) to identify potential failure modes in human-involved process steps.
• Employed Process Reengineering methodologies to analyze and redesign processes for reduced human error.
• Examined case examples to illustrate findings on human-related risks.

Main Results:

• Identified inherent weaknesses in process design as a primary driver of human error, rather than solely personnel factors.
• Demonstrated that FMEA and Process Reengineering can effectively uncover and address risks linked to human intervention.
• Highlighted the critical need to integrate human factors into validation strategies.

Conclusions:

• Process design improvements are crucial for mitigating risks associated with human intervention.
• Effective validation requires a comprehensive approach that includes analyzing and optimizing human-machine interactions.
• Enhanced training and qualification programs must be informed by a thorough understanding of human-related process risks.
