Answer Question based on either English passage :
Despite its extraordinary name `ergonomics' is not just something which has been dreamed up by boffins to confuse busy businessmen. It is a practical science which can make and is making a valuable contribution to industry. Research being carried out in this field can increase efficiency, improve product design and make employees more contented.
Broadly, ergonomics is the study of the relationship between man and his working environment. It involves designing or redesigning machines and equipments so that due regard is given to the capabilities and limitations -- physical and psychological -- of the human beings who have to use or operate them.
In contrast to the more common, traditional policy of `fitting the man to the machine' by selecting and training the best man for each particular job, the ergonomist endeavours to fit the machine to the man-any man.
He accepts people, in fact, as he finds them with all their quirks and idiosyncracies, and tries to establish their capabilities as machine operators. He then attempts to allocate to the human operator the functions each can perform best. His object is to enable a person of ordinary abilities to carry out his tasks safely and efficiently, with a minimum of instruction.
The ergonomist himself needs a knowledge of a number of sciences and techniques in order to carry out his work.
