Abstract :
SOME years ago a prominent member of a group of engineers, who at that time called themselves “efficiency” engineers, had for a pet slogan the expression “whatever is, is wrong.” For the present purpose any objections to this saying from the standpoint of syntax will be passed by but it has been observed that methods and procedures that for years have been refined in the crucible of practice usually have survived because they do have merit. Nevertheless the field of technology is anything but a quiescent one and it is desirable, therefore, that long existing methods, procedures, and standards be subject to constant scrutiny in the light of new developments.
