Overview
What it means
Ergonomics takes a systems approach across physical (posture, load, repetitive work), cognitive (workload, decision-making, interface design) and organisational domains. Its premise is that humans are problem-solvers, not the problem: accidents and strain arise from system design, so design should fit the human rather than forcing adaptation.
How it is used
Applied in workplace design, musculoskeletal-disorder prevention, product and interface design, and safety management; referenced in occupational-health reporting.
Why it matters
Poor ergonomic design drives a large share of work-related ill health (notably musculoskeletal disorders); good design simultaneously improves health and productivity.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
