Data
Information
Quantitative (Numeric) data Discrete Continuous
Qualitative (Categorical) data Ordinal Nominal
4
Histogram
Dispersion

• Applications
• To analyze process and discover items to be
  improved
• To research process capability
• To control the process (in a time series)
• To verify effects of an improvement

Stratified by separate machines, operators, times
of day, material
5
Pareto 80/20 rules

• Applications
• To establish targets for control and improvement
• To verify results of control and improvement
  activities

Identify the most important causes that
contribute to a great effect
6
Graphic presentation of data

• Applications
• To understand relative sizes of numbers
• To understand trends over time
• To understand percentages of total

7
Correlation analysis

• Applications
• To study correration
• To determine the most appropriate levelfor
  control

Discover relationships causes effects,
between different causes/effects
8
Causes and Effect Diagram

• Applications
• To understand the relationship between effect
  characteristics and causes factors
• To clarify problem areas and establish corrective
  actions
• To establish control items and perfect
  cross-positional management

9
Causes and Effect Diagram

• Clearly define a characteristic as a problem
• Identify all factors
• Sort out the factors into the diagram
• Check if any change in factor causes a
  corresponding change in characteristic and vice
  versa
• Check if the end factor can change its condition
• Determine important factors
• Devise countermeasures to those important ones

10
Check-sheet techniques

• Applications
• Inspections
• Records
• Tests

11
Control Charts

• Applications
• To control a process
• To analyze a process

12
Other IE techniques

• Process analysis
• Work study
• Failure Mode and Effects Analysis (FMEA)
• Design of Experiments (DOE)
• Value Engineering (VE)
