Time Study Time study is a structured process of directly observing and measuring human work using a timing device to establish the time required for completion of the work by a qualified worker when working at a defined level of performance. It follows the basic procedure of systematic  work measurement  of: analysis  of the work into small, easily-measurable components or elements measurement  of those components and synthesis  from those measured components to arrive at a time for the complete job. The observer first undertakes preliminary observation of the work (a pilot study) to identify suitable elements which can be clearly recognised on subsequent occasions and are of convenient length for measurement. Subsequent studies are taken during which the observer times each occurrence of each element using a stopwatch or other timing device while at the same time making an assessment of the worker's rate of working on an agreed rating scale. One of the prime reasons

Predetermined motion time systems (PMTS) Predetermined motion time systems (PMTS) are  work measurement  systems based on the analysis of work into basic human movements, classified according to the nature of each movement and the conditions under which it is made. Tables of data provide a time, at a defined rate of working, for each classification of each movement. The first PMTS (since designated as "first-level" systems) were designed to provide times for detailed manual work and thus consisted of fundamental movements (reach, grasp, move, etc) and associated times. Large amounts of research, data collection, analysis, synthesis, and validation are required to produce PMTS data and the number of such systems is very low. "Higher level" systems have since been devised, most commonly by combining these fundamental movements into common, simple manual tasks. Such higher level systems are designed for faster standard setting of longer cycle activity. Critici

Work Measurement in Textile Industry Work Measurement: Work measurement is the application of techniques designed to establish the time for an average worker to carry out a specified manufacturing task at a defined level of performance (to measure the time of a work for a worker). It is concerned with the length of time it takes to complete a work task assigned to a specific job . Work Measurement in Textile Industry Objectives of Work Measurement:  1. Work study:  Work measurement is needed when we do work study.  Work study  or research can help to develop a current working procedure.   2. Comparison of alternative method:  By doing comparison better method can be found.  Example:  We have two methods and two are good, but after calculating the time we can see that one is taking less time than that of other. In that case we can select the less time select one (job). 3. Worker appointment:  By counting or measuring the works of a worker we can select

Techniques of Work Measurement and Their Applications Work measurement (WM) Work measurement  is the application of techniques designed to establish the time for a qualified worker to carry out specified jobs at a defined level of performance.  Work measurement (WM) is concerned with investigating, reducing and eliminating ineffective time, whatever may be the cause.  WM is the means of measuring the time taken in the performance of an operation or series of operations in such a way that the ineffective time is shown up and can be separated out.  Work measurement is also called by the name ‘ time study ’. Work measurement is absolutely  essential for both the planning and control of operations. Without measurement data, we cannot  determine the capacity of facilities or it is not possible to quote delivery dates or costs. We  are not in a position to determine the rate of production and also  labor utilization  and efficiency.  It may not be possible to introduce incent
