Practical ergonomics: Designing work for people, productivity and profit

IN Sri Lanka, senior executives spend a considerable time debating productivity —how to improve output, reduce costs, retain skilled employees, and remain competitive in increasingly demanding markets.

The discussion often centres on automation, digitalisation, lean systems, and capital investment. Yet one of the most powerful productivity tools is frequently overlooked because it appears deceptively simple: ergonomics.Ergonomics is not about luxury chairs or fashionable offices. It is about designing work, tools, machines, and environments to match human abilities and limitations. Organisations that apply ergonomic thinking consistently achieve higher productivity, better quality, fewer injuries, and stronger employee commitment—often with minimal capital expenditure.

The word ergonomics comes from the Greek ergon (work) and nomos (laws). In practical terms, ergonomics means fitting the work to the worker, rather than forcing the worker to fit poorly designed work.

One of the most frequently cited ergonomic design examples is the Coca-Cola bottle. Its iconic contoured shape was not designed purely for aesthetics. It fits naturally into the human hand, provides a secure grip even when wet, and can be recognised by touch alone. This design reduces effort, improves usability, and enhances user experience—all fundamental ergonomic principles.

The same logic applies to:

The placement of gear levers in modern vehicles

The shape of a hacksaw handle

The layout of mobile phones and ATM keypads

The height and reach of a factory workstation

Good ergonomic design feels “natural” because it respects how the human body works.

From a management perspective, ergonomics delivers measurable benefits on two fronts.

Higher productivity and consistent output

Improved quality and fewer defects

Reduced workplace injuries and medical costs

Lower absenteeism and staff turnover

Better on-time delivery and customer satisfaction

Reduced fatigue and discomfort

Fewer musculoskeletal injuries

Improved morale and job satisfaction

Better quality of work life
