Work study• Work Study is the systematic examination of the methods of carrying out activities such as to improve the effective use of resources and to set up standards of performance for the activities carried out. • it is a management tool to achieve higher productive efficiency of the organisation .Work study is also define as that body of knowledge concerned with the analysis of the work methods and equipments used performing a job.

Objectives of work studySimplifying or modifying the

methods of operationReduces unnecessary or excess

workStops wasteful use of resourcesContributes to industrial safety

by identifying hazardous work and developing safer methods

Cuts down the time of performing a certain activity.

Benefits of work studyIt help us in increase productivity.Reduce manufacturing cost.Improve place layout.Better man power and planning.

METHODS

Method study Work measurement

METHOD STUDY Method-study concerned with “the way in which work

is done (i.e., method)”. It is used to simplify the way to accomplish a work and to improve the method of production. Method-study results in a more effective use of material, plant, equipment and manpower. Method study is essentially concerned with finding better ways of doing things. It adds value and increase the efficiency by eliminating unnecessary operations, avoidable delays and other forms of waste.

The improvement of efficiency is achieved through: 1.Present and analysis true facts concerning the situation.

2.To examination those facts critically 3.To develop the best answer possible under given

circumstances based on critical examination of facts.

Procedure of method study

Procedure to accomplish method study, called "SREDIM" shall be as follow:

1. Select: the job or operation that needs improvement,

2. Record: all facts, how work is done by chart methods,

3. Examine: every aspect of the job by asking; what, why, where, when, who and how

4. Develop: review ideas, eliminate, simplify, combine, re-arrange, make new method which more safe, chart new method, submit for approval,

5. Install: the new method, consider best time to introduce, convince all, train users,

6. Maintain: check frequently, match results, correct deviations.

Process charts in method study :)Outline process chart :> it records overall pictures

of the process and record only main events sequence wise.

Operation process chart :> The operation process chart shows the chronological sequence of all operations, inspections, time allowances, and materials used in a manufacturing or business process, from the arrival of raw material to the packaging of the finished product.

Flow process chart (man-type, material-type and equipment-type): This is the use of symbols and description to chart the sequence of work. The process, then, show what is happening at different stages. The distances and time may be given. A flow process chart is a chart of all the activities involved in a process.

Two handed process chart :> in this chart activities of a workers or operators both hands are recorded chronologically.

Multiple activities chart :> This technique is used to solve problems where a number of items are dependent on each other. The aim is to reduce idle times by using the optimum number of each item.

Flow diagram :> It depicts the probable movement or position of materials and equipments in the floor plant. The movement is represented by a line in the plant drawing.

Work measurementWork 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 or at a defined rate of working.

A qualified worker is one who has acquired the skill, knowledge and other attributes to carry out the work in hand to satisfactory standards of quantity, quality and safety.

Defined rate of working is the amount of work that can be produced by a qualified worker/employee when working at normal space and effectively utilizing his time and where work is not restricted by process limitation.

Purpose of work measurementTo reveal the nature and extent of ineffective

time, from whatever cause, So that action can be taken to eliminate it; and

then,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.

Uses of work measurement:

To compare the efficiency of alternative

methods. Cost estimation Pricing of products and services Incentive pay systems Capacity planning Production scheduling To provide information on which estimates

for tenders, selling prices and delivery promises can be based.

To reduce the waste of production delay.To maximize the manpower utilization by

minimize the idle time of the operation .
