What are the 7 basic tools of quality control?

The 7 Quality Control (QC) Tools are fundamental methods for improving quality, developed by Kaoru Ishikawa, including Cause-and-Effect Diagrams (Fishbone/Ishikawa), Check Sheets, Histograms, Pareto Charts, Control Charts, Scatter Diagrams, and Flowcharts (or Stratification/Run Charts), used to analyze, understand, and solve process problems by visualizing data, identifying root causes, and monitoring process stability for better decision-making and efficiency.

What is Pareto chart in 7 QC tools?

The basic Pareto chart is designed to compare the frequencies of an occurrence, according to problem categories. In the figure below you can see that the measured data (bars) are arranged according to categories and plotted against the corresponding frequency. The categories, or bars, are listed in decreasing order.

A quality control checklist is a standardized tool used to ensure that products or processes meet specific quality requirements. It typically includes criteria such as specifications, tolerances, inspection steps, and documentation requirements.

What are the 4 types of quality control?

The four common types of quality control (QC) focus on different stages of production: Process Control (keeping processes stable), Control Charts (tracking variations over time), Acceptance Sampling (checking product samples from batches), and Product Quality Control (inspecting finished goods). Other categorizations focus on inspection phases (pre-production, during production, pre-shipment, container loading) or quality management pillars (planning, assurance, control, improvement).
