Work Study

3

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).

Method Study

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.

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

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.

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.

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)

Recording Techniques

Charts1.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.

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.
