7 QC Tools

A Process Flow Chart (PFC) in manufacturing is a diagram of the separate steps of a operations/process in sequential order. PFC also known as process flow diagram (PFD), and Process Map. PFC is a process analysis tool that can be used to describe various processes, such as: Manufacturing process, Project planning, and Service sectors etc. […]

“Fishbone Diagram” also known as “Ishikawa diagram” and “Cause and Effect diagram. It helps to Identify all potential or probable causes and select the best cause which contributes to the problem/effect. The brainstorming technique is used here for potential cause identification. In a brainstorming session, all 4M or 6M factors are taken into consideration to

Scatter Diagram is also known as Correlation Chart, Scatter Plot, Scatter Chart, and Scatter Graph. Scatter Graph is used to find out the relationship between the two variables. Independent variable data and dependent variable data are customarily plotted along the horizontal X-axis and Vertical Y-axis respectively. Independent variable is also called as controlled parameters. It

Stratification is a statistical technique of breaking down value/data into meaningful categories or classifications. This is considered one of the basic 7 QC Tools and is extensively used in Problem Solving Techniques such as 8D, PDCA, and Six Sigma. Stratification Definition and Meaning Stratification is a technique or method that can be defined in many

Control chart is also known as SPC chart or Shewhart chart. It is a graphical representation of the collected information/data. And helps to monitor the process centering or process behavior against the specified/set control limits. Control chart is a very powerful tool to find/investigate the source of Process Variations present in the manufacturing processes. Tells

A Histogram is a pictorial representation of a set of data, and the most commonly used bar graph for showing frequency distributions of data/values. It is created by grouping the measurements into “cells” or “class ” or “bins”. It is similar to the bar chart, but it groups data points into classes and plot frequencies.

Check Sheet is also called as Tally Sheet and is used for collecting and analyzing data. Data collection is an important activity in the problem solving process as it provides a basic for further action. A data may be numerical, observations and opinion. This is the basic and very important tool of 7 QC Tools

7 QC Tools are also known as Seven Basic Quality Tools and Quality Management Tools. These graphical and statistical tools are used to analyze and solve work-related problems effectively. The 7 Quality Tools are widely applied by many industries for product and process improvements, and to solve critical quality problems. 7QC tools are extensively used
