Human Factors and Ergonomics (HFE), also known simply as ergonomics is the science of designing work, systems, and products to fit people. The term “ergonomics” comes from the Greek words ergon (work) and nomos (laws).

HFE focuses on understanding how people interact with technology, environments, and organizations. Its goal is to improve human well-being and overall system performance.

• People are assets, not just resources.
• Technology should support humans, not replace them.
• Design should promote health, safety, and quality of life.
• Respect individual differences and diverse needs.
• Consider the impact of design decisions on all stakeholders.

HFE applies to almost every aspect of life and work, including:

• Tasks & Jobs: Designing tools, processes, and procedures that are safe and efficient.
• Products & Systems: Ensuring usability, accessibility, and comfort in everyday technologies.
• Workplaces & Organizations: Improving safety, communication, and collaboration.
• Society & Policy: Shaping standards, regulations, and sustainable systems that affect communities. 

HFE considers both the micro level (equipment, tools, tasks) and the macro level (organizations, roles, policies, and culture).

• Safer and healthier work environments.
• Higher productivity and better quality outcomes.
• Reduced costs from errors, injuries, and turnover.
• More sustainable organizations and societies.

In short: HFE makes systems work better for people, for businesses, and for society.
