This will mean a lower probability of error, less likelihood of accidents, less time correcting mistakes and better morale. The cost of ergonomics depends where in the lifecycle of a systems it is applied. Applied as a reaction to serious problems, then costs will be higher. Fitting the job to the people who have to do it, through the design of equipment and procedures. Fitting the person to the job, through use of placement procedures or training.
Application requires matching task demands and environmental conditions with user characteristics.
However, it is usually not so simple to put principle into practice and a number of techniques have been developed to help this process. Ergonomics draws on engineering and design methods as well as life science and behavioural science knowledge.
