Work Study is a generic term for management services and
system engineering techniques, used to investigate:
Methods of performing work (Method Study).
The time taken to do it (Work Measurement).

5. Method Study
5
Method study is a technique to reduce the work content mainly
by eliminating unnecessary movements by workers, materials, or
equipments.
However, even after that, there could be substantial unnecessary
time taken for the process because of lack of management control
or inaction of worker.
Method Study approaches and tools of Method Analyst:
Flow Diagrams & Process Charts etc.
Critical questioning techniques.

6. Method Study
6
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.
Used to analyze
Movement of body, people, or material
Activities of people & machines

7. Method Study Objectives
7
Improvement of processes and procedures.
Improvement in the design of plant and equipment.
Improvement of layout.
Improvement in the use of men, materials and machines.
Economy in human effort and reduction of unnecessary fatigue.
Development of better working environment.

8. Method study - Methodology
8
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.

Exploratory Tools
Pareto Analysis
Fish & Bone Diagrams
Gantt and PERT charts
Recording and Analysis Tools
Operation Process Chart
Flow process chart
Flow diagram
Worker and Machine Process Charts
Gang Process charts
Synchronous Servicing

11. Method Study Applications
11
The need for methods analysis can come
from a number of different sources :
Changes in tools and equipment.
Changes in product design or new products.
Changes in materials or procedures
Other factors (e.g. accidents, quality problems)

12. Recording Techniques

Charts
1.Outline process chart.
2.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.
3.Two hands process charts.
4.Multiple activity charts: 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. It depicts the occupied times-broken down into the
number of different activities and the idle times both for the
original and proposed methods of doing the job.

13. Recording Techniques (Cont.)

Diagrams and models (2-D and/or 3-D)
1.Flow diagrams, which is the use of symbols for flow process
charts, superimposed on drawings and the "descriptions" are not
necessary.
2.String diagrams, which is used for solving movement problems
since it shows congestions and excessive distances.
3.Cut-out templates (2-D models).
4.3-D models.
