Matrix Data Analysis
Principal Component Analysis
Technique quantifies and arranges data
presented in Matrix
Based solely on numerical data
Finds indicators that differentiate and
attempt to clarify large amount of
information

Matrix Data Analysis
Advantages of Principal Component Analysis
Can be used in various fields (market surveys, new
product planning, process analysis)
Can be when used when Matrix diagram does
not give sufficient information
Useful as Prioritization Grid

Constructing a Prioritization Grid
Source: Foster, S., Managing Quality (Upper Saddle River, NJ: Prentice Hall, 2001)
Slide 3 0f 6
Determine your goal, your alternatives, and
criteria for decision
Place selection in order of importance
Sum individual ratings to establish overall
ranking (Divide by number of options for average
ranking)
Apply percentage weight to each option (all
weights should add up to 1)
11. New Seven Q.C. Tools
Matrix Data Analysis

Slide 4 0f 6
Rank order each option with respect to
criterion (Average the rankings and apply a completed
ranking)
Multiply weight by associated rank in
Matrix (in example, 4 is best, 1 is worst)
Result is Importance Score
Add up Importance Scores for each option

- Eagerness to solve problem
- Be highly motivated for the challenge
Keys to Successfully Using the
New Seven Q.C. Tools
Slide 1 0f 5
Four Specific Keys
Understand the problem
Select the right tool for the job
Obtain appropriate verbal data
Interpret analytical results
15. Keys to Successfully Using the
New Seven Q.C. Tools
Slide 2 0f 5
Understand the problem
Stage 1 - problem is unclear and not obvious
what exact issue should be addressed
Stage 2 - problem is obvious, but causes unknown
explore causes and single out valid ones
Stage 3 - problem and causes are known
required action is unknown
strategies and plan must be developed
4 Specific Keys
16. Keys to Successfully Using the
New Seven Q.C. Tools
Slide 3 0f 5
Selecting Right tool for the Job
Stage 1 - Collect verbal information on events
(Affinity Diagram)
Stage 2 - Choose tool to identify causes
(Relations Diagram / Matrix Diagram)
Stage 3 - List strategies and activities
(Tree Diagram / Relations Diagram)
Plan actual activities
(Arrow Diagram / PDPC Chart)

17. Keys to Successfully Using the
New Seven Q.C. Tools
Obtaining appropriate verbal data
Three types of verbal data:
- Facts; factual observations expressed in words
- Opinions; factual information colored by opinion
- Ideas; New concepts created by analyzing facts
.Group Discussions:
- Ensures common understanding
- All data should be without bias or distortion
- Data should fit objective of the analysis

18. Keys to Successfully Using the
New Seven Q.C. Tools
Slide 5 0f 5
Interpreting Analytical Results
Information must be obtained for accomplishing
objectives from:
- Completed diagrams; or
- Process of completing diagrams
Analyze actual information obtained:
- Prepare summarized report with findings,
conclusions, and processes used
- Check if necessary data has been obtained, if not
- Discover the cause and take appropriate action
