The 7 quality tools are fundamental for companies seeking to improve processes, increase efficiency, and ensure customer satisfaction. These tools are widely used in Quality Management Systems and are essential for identifying and solving problems, promoting continuous improvement, and optimizing organizational performance. Learn more about them:

• Cause and Effect Diagram (Ishikawa): Also known as the fishbone diagram, this tool helps identify, categorize, and analyze the root causes of a specific problem, facilitating the development of effective solutions.
• Check Sheet: Used to systematically collect and record data, the check sheet is a simple and effective tool for monitoring processes and identifying patterns or trends.
• Histogram: A histogram is a bar chart that represents the distribution of a set of data. It is useful for visualizing variability and the frequency of events occurring in a process.
• Pareto Chart: Based on the Pareto principle, this tool helps identify the most significant causes of a problem, allowing companies to focus their efforts on the areas that will have the greatest impact.
• Scatter Diagram: The scatter diagram is used to analyze the relationship between two variables. It helps identify correlations and patterns that may indicate the cause of problems or areas for improvement.
• Flowchart: A flowchart is a graphical representation of a process. It helps visualize each stage of the process, identify inefficiencies, and optimize workflow.
• Control Charts: These charts are used to monitor the stability and variability of processes over time. They help identify deviations and take corrective action before major problems occur.
