Work study : It is defined as that body of knowledge concerned with the ANALYSIS OF WORK METHODS AND EQUIPMENT used in performing a job, the DESIGN OF AN OPTIMUM WORK METHOD and the STANDARDISATION OF PROPOSED WORK METHODS .
The purpose of work study is to determine the best or most effective method of accomplishing a necessary operation
Time study and motion study are results of practices developed by F.W. Taylor, Frank and Lillian Gilbreth.
“ METHOD STUDY is the systematic recording and critical examination of EXISTING and PROPOSED WAYS of DOING WORK as a means of DEVELOPING and APPLYING EASIER AND MORE EFFECTIVE METHODS and REDUCING COSTS” (B.S.I)
Motion study is the science of eliminating wastefulness resulting from using unnecessary; ill-directed and inefficient motion. The aim of motion study is to find and perpetuate the scheme of least waste methods of labour.
Micro motion study provides a valuable technique for making minute analysis of those operations that are short in cycle, contain rapid movements and involve high production over a long period of time.
“ TIME STUDY is a work measurement technique for recording the time and rating for the elements of a specified job carried out under specified conditions and for analyzing the data so as to obtain the time necessary for carrying out the job at a defined level of performance by a qualified and trained worker” (B.S.I)
Analytical Estimating./Pre determined Motion Time System (PMTS)./Work sampling or Activity Sampling or Ratio Delay Method.
Work measurement involves 7 STEPS.
1.Break the job into elements/2.Record the observed time for each element by means of either time study, synthesis or analytical estimating./3.Establish elemental time values by extending observed time into normal time for each element BY APPLYING A RATING FACTOR ./4.Assess relaxation allowance for personal needs and physical and mental fatigue involved in carrying out each element./5.Add the relaxation allowance time to the normal time for each element to arrive at the work content.
/6.Determine the frequency of occurrences of each element in the job, multiply the work content of each element by its frequency ( i.e., number of time the element occurs in the job) and add up the times to arrive at the work content for the job./7.Add contingency allowance if any to arrive at the standard time to do the job.
