7 Basic Problem Solving Tool

7QC Tools Problem Solving Method

The 7 QC (Quality Control) Tools, also known as the 7 Basic Tools of Quality, are a set of techniques used in quality management to identify and solve quality-related issues. These tools were originally developed by Kaoru Ishikawa, a Japanese quality control expert, and are widely used in various industries to improve processes and products. Here are the 7 QC tools:

1. Check Sheet: A check sheet is a simple data collection form used to gather and record data in a systematic manner. It helps in organizing and categorizing data to identify patterns or trends.
2. Histogram: A histogram is a graphical representation of data that displays the frequency distribution of a set of values. It provides a visual representation of the data’s distribution, allowing you to identify the central tendency, variation, and shape of the data.
3. Pareto Chart: A Pareto chart is a combination of a bar graph and a line graph. It presents data in descending order of frequency or impact, highlighting the most significant factors or problems. It helps prioritize improvement efforts by focusing on the vital few issues that contribute to the majority of the problems.
4. Cause-and-Effect Diagram (also known as Fishbone or Ishikawa diagram): This tool is used to identify and explore the potential causes of a specific problem. It organizes possible causes into categories such as people, methods, materials, machines, measurement, and environment, allowing you to visualize the relationships between various factors and the problem.
5. Scatter Diagram: A scatter diagram is a graph that shows the relationship between two variables. It helps identify any correlation or relationship between the variables and determines if a change in one variable affects the other.
6. Control Chart: A control chart is a statistical tool used to monitor a process over time. It displays data points in relation to control limits, which are calculated using historical data. Control charts help identify variations in a process and determine if it is in a state of control or experiencing special cause variation.
7. STRATIFICATION: It often used for that data breakdown into meaningful data. Like Monthly data breakdown into, week, Day, shift and minimum into hrs. These data stratifications are used to analyse the data.

These tools are often used together as part of a comprehensive quality improvement approach and can assist in problem-solving, decision-making, and continuous improvement efforts.
