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 for further validation to find the actual root cause of the problem and necessary actions. The potential cause identification carried out using tools or techniques like brainstorming and fishbone diagram. In a brainstorming session,

A Scatter diagram is utilized to determine the relationship between the two set of variables. The terms correlation chart, scatter plot, scatter chart, and scatter graph are other names for scatter diagrams. Plotting data for independent and dependent variables typically follows the vertical Y-axis and the horizontal X-axis, respectively. Another name for an independent variable

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

A Control Chart is a statistical tool that is used to monitor and control process stability or process behavior, and improve process performance over time. It is also known as Shewhart Chart or Process Behavior Chart or SPC chart. A Control Chart is very important part of SPC (Statistical Process Control) tool. It helps to

A Histogram is a pictorial representation that shows the frequency distribution of numerical data. Histogram displays the data in bar where each bar indicates the frequency (called a “count”) of data points or measurements that fall within a specific interval or range (called a “bin”). It is created by grouping the measurements into “cells” or

Check Sheet is also called as Tally Sheet. It is a structured or prepared form used for recording, collecting, and analyzing data in a organized and systematic way. A Check Sheet is mainly used for collecting data (data can be in the form of observations, opinion, and numerical) in real-time at location where the data

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
