Introduction: The seven QC Tools were developed by Prof. Kaoru Ishikawa, “The father of QCC’s”. Through his experience, he identified a set of tools which can be used by teams and individuals to interpret the data fully and derive the maximum information out form it. These are seven effective methods which will offer any organization means of collecting, presenting, and analyzing most of its data and problems. They are ; Process flow diagram, Check Sheet, Histogram, Pareto Analysis, Cause and effect analysis, Scatter diagram, and Control Charts. The course include the use of basic statistical process control techniques like Measure of central tendency, Measure of dispersion, Skewness, Correlation analysis theory and practice in MS Excel. Tools No. 1: Process Flow Diagram What is process flow diagram. Application and use of process flow diagram. Value added and non-value added steps. Construction of process flow diagram. Illustrative worked examples. Measuring cycle time and process efficiency. Tool No. 2 : Check Sheet What is check sheet? Application and use of check sheet. Construction of Check Sheet. Difference between defect and defective. Illustrative worked examples. Tool No. 3 : Cause and Effect diagram What is cause and effect diagram? Why is it known as fishbone diagram and Ishikawa diagram? Application and use of cause and effect diagram. Construction of cause and effect diagram. Brainstorming. Essentials for organizing brainstorming sessions. Illustrative worked examples. Tool No. 4 : Histogram What is histogram? What is SPC(Statistical Process Control). Shapes of histogram. Application and use of histogram. Manual construction of histogram. Histogram for ungrouped data. Histogram for grouped data. Illustrative worked examples. Construction of histogram in MS-Excel. Tool No. 5 : Pareto Diagram What is Pareto diagram? Who was Pareto? What is ABC analysis and 80-20 rule? Application and use of Pareto diagram? Calculation of cumulative frequency. Finding vital causes of a problem compared to trivial many. Construction of Pareto chart manually. Step by Step construction of Pareto chart in MS-Excel. Illustrative worked examples. Tool No. 6 : Scatter Diagram What is scatter diagram? Application and use of scatter diagram. Interpretation of different patterns of scatter diagram. Correlation Coefficient ; Algebraic value of relationship between two variables (X and Y). Method of calculation of coefficient of correlation r. Table for calculation. Interpretation of value of r. Construction of scatter diagram manually. Construction of scatter diagram in MS Excel. Illustrative worked examples Tool No. 7 : Control Charts What is Control Chart? Types of control charts : Mean(Bar) Chart, Range(Run) Chart. Meaning of accuracy and precision. Archers bow and target analogy for understanding accuracy and precision. How control chart help to maintain accuracy and precision of process? Application and use of control chart. How continuous use of control chart show improvement in quality? Control limits; Upper control limit, Lower control limit. Manual construction of mean chart and range chart. Construction of mean chart and range chart using MS-Excel. Illustrative worked examples.
