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
4 Specific Keys (cont.)
Trang 62Keys to Successfully Using the
New Seven Q.C Tools
Slide 5 0f 5
Information must be obtained for accomplishing
objectives from:
- Completed diagrams ; or
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
