Crossing levels in systems ergonomics: a framework to support 'mesoergonomic' inquiry

Area of Science:

• Human Factors and Ergonomics (HFE)
• Systems Ergonomics
• Open Systems Theory

Background:

• Existing research in human factors and ergonomics (HFE) is often divided into microergonomics and macroergonomics.
• A gap exists in understanding the relationships between different system levels within HFE.
• There is a need for an integrated approach to bridge micro- and macroergonomic domains.

Purpose of the Study:

• To introduce and define mesoergonomics as a novel approach within HFE.
• To propose a framework for structuring mesoergonomic investigations.
• To demonstrate the utility of mesoergonomics through case studies.

Main Methods:

• Defining mesoergonomics as an open systems approach studying HFE variables across at least two system levels.
• Presenting a four-step framework: establishing purpose, selecting variables, choosing investigation type, and relating system levels.
• Illustrating the framework with two case studies.

Main Results:

• Mesoergonomics provides a structured method to integrate HFE research across different system echelons.
• The proposed framework facilitates empirical and conceptual inquiry in systems ergonomics.
• Case studies highlight the practical value of a mesoergonomic perspective.

Conclusions:

• Mesoergonomics offers a valuable perspective for advancing human factors and ergonomics research.
• The framework serves as a guide for future mesoergonomic studies.
• Further research agendas in systems ergonomics can benefit from mesoergonomic principles.
