MEANINGy Work measurement is the application of techniques

designed to establish the time for a qualified workertocarry out specified jobs at a defined level of performance.

y total time to manufacture a product is increased by:adding undesirable features to product,bad operation of the processes, and

ineffective time added because of worker andmanagement.

y All this leads to decreased productivity.


16/23

Purpose ofWMy To reveal the nature and extent of ineffective time,

from whatever cause,

y So that action can be taken to eliminate it; and then,y To set standards of performance that are attainable

only if all avoidable ineffective time is eliminated and

work is performed by the best method available.
