2. 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.

3. Objectives of work study
 Simplifying or modifying the methods
of operation
 Reduces unnecessary or excess work
 Stops wasteful use of resources
 Contributes to industrial safety by
identifying hazardous work and
developing safer methods
 Cuts down the time of performing a
certain activity.

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

5. METHODS
 Method study
 Work measurement

6. 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.

7. 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.

8. 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.

9.  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.

10. Work measurement
 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
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.

11. Purpose of work
measurement
 To 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.

12. 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 .
