Ergonomics / Human factors

Ergonomics / Human factors

1. GOOD ERGONOMICS

   • Systems Ergonomics

2. SYSTEMS E/HF

   • Examines, accounts for and enhances the design of a system, and people’s interactions with it.
     • artefact, facility, environment, worksite group, etc.

3. SYSTEM

   • set of inter-related or coupled activities or entities, with a joint purpose.
   • Human System Interaction
     • understanding, designing and supporting human roles and performance in complex systems
   • System Engineering
     • Evolving user needs, and incremental development of specifications.
       • Includes integration of all disciplines throughout the system life cycle

4. FEATURES

   • SYSTEM FOCUS
     • treats the focus of interest as a system
       • as an interacting combination of DNA, materials (organic and inorganic), bytes, functions/processes and ideas
   • CONTEXT
     • shows where and how system boundaries operate and how each can provide context for others
       • Context behaviour and performance takes place in a setting or a context
   • INTERACTIONS
     • ntegration of human, technical, information, social, political, economic and organisational components
       • E/HF is about understanding and design for the interactions not the components in the system
   • HOLISM
     • systems should be seen as a whole
       • the cognitive, physical and social must be combined in the same view
         • Design change expected to produce safety benefits should produce benefits to all areas
   • EMERGENCE
     • recognition of the emergent properties of systems
       • 1. All systems in real use, will display characteristics and operate in ways not expected.
       • 2. People find ways to accommodate, avoid, or work around system deficiencies in designs
       • 3. People unexpectedly take advantage of capabilities in a product or role not dreamed of by designers
   • EMBEDDING
     • the way ergonomics fits within the organisational system
       • working with all key stakeholders and subject matter experts
