Contribution
1. User Friendly Quality Control
• It showed the importance of the seven quality tools: control chart, run chart, histogram, scatter diagram, Pareto chart, and flowchart.
2. Fishbone Cause and Effect Diagram
• The fishbone will help to visually display the many potential causes for a specific problem or effect. It is particularly useful in a group setting and for situations in which little quantitative data is available for analysis. 3. Implementation of Quality Circles
• Quality Circle is appealing but a Quality Circle can only be developing if management will take action on the recommendations of the Circle. When the management has no interest in participation as is often the
