2
• Make life easier and more comfortable
• Get job done completely and faultless
• Get people achieve higher level of living
standard
3
• Problem Solving
• Process Analysis
• Operation Analysis
• Micromotion Study
• Time Study (Work Measurement)
• etc.. such as Applied Statistics
4
Knowledge dealing with the systematic
determination of a preferable work method with
the time required for the uses of human and
equipment to perform such work as well as a
development of material & tools to make the
established method and time practical
5
Procedure to describe, systematic analyze
and improve work method
Thus consider
Method
Engineering
• Work process
• Raw materials
• Design of the output
• Workplace, tools, equipment
at each step of the work process
• Human activities

• Separately constructed for
Man - Machine - Material Flows
• Process Chart and Flow Diagram are
complementary
• Always complete all chart headings &

What are revealed information?
• time consumed
• transportation distance
• required man-hour
What Next ?
21
How to develop a better method
• Graphic Tools for the analysis
• 5W + 1H Questions
• ECRS
• Checklists
• More details: Micromotion study
22
What is done?
? Why should it be done
Who does the work?
?
Where is the work done?
When is the work done?
How is the work done?
Why does she do it
?
Why should it
be done here
?
Why should it be
done this time
?
Why is it be done
23
this way
Output of the questions…s
Objectives of the work
Creativity:
Could any other people do this
work better in other place, at other time,
using other method?
24
Along with 5W1H,
TRY US!
E eliminate all unnecessary work
C combine operations (elements of work)
R rearrange sequence of operations
S simplify the necessary operations
25
Operation
• Improve the equipment performance
• Is current production lot size too large or too
small?
&
at each operation !!!
26
Transportation
•
Create
•
Change the layout to eliminate distance
•
Increase the lot size per trip
•
Do the loading & unloading time take too long?
•
Improve transportation equipment
&
and
at each transportation !!!
27
Inspection
•
Create
•
Improve inspection method
•
Are the quality inspections and volume
inspections being done at separate processes?
Try to combine the two at the same process
&
at each inspection !!!
28
and
•
Can we create
storage?
•
Can retention times be shorten?
to eliminate temporary

Expenses & Benefit of Study
•
Extensiveness of task
•
Life of the task
•
Labor consideration
•
Investment
33
Value Engineering
Achieve the economy of time,
materials, human effort and money
Ergonomic
Make the
necessary human effort
easier and easier
