Quality Control(การควบคุมคุณภาพ) : การตรวจสอบผลิตภัณ ฑ TQM เป น ชุด ของ กิจกรรมที่มีวิธีการดําเนินการอย า งเป น ระบบ 6) แผนภูมิควบคุม (Control Chart). Draw Quality Control Charts, Cause-and-Effect Diagrams, and Other Diagrams for ISO, TQM and Six Sigma. SmartDraw quality control chart software lets you in the field of TQM is familiar with control charts and statistical process improvement for Quality. A number of tools, including the Six Sigma tool box, are made up Pareto chart (80/20 Rule); Scatter diagram (Shewhart Chart); Control chart. 1. Stratification (Divide and Conquer). Stratification is a method of dividing data into The purpose of Control Chart is to maintain the production conditions in stable or statistical control ones. In this method, thus, the upper and lower control limits Control charts show the performance of a process from two points of view. First, they show a snapshot of the process at the moment data is collected. Second, they show the process trend as time progresses. Process trends are important because they help in identifying the out of control status if it actually exists.
When total quality management (TQM) was explored, W. Edwards Deming added elements to control charts to assess every area of a process or organization. According to SCQ Online, Walter Shewhart’s thought was that, “no matter how well the process is designed, there exists a certain amount of nature variability in output measurements."

Control chart: Graph used to study how a process changes over time. Comparing current data to historical control limits leads to conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation).
Control charts, also known as Shewhart charts (after Walter A. Shewhart) or process-behavior W. Edwards Deming · Process capability · Seven Basic Tools of Quality · Six Sigma · Statistical process control · Total quality management The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average Control charts have long been used in manufacturing, stock trading algorithms, and process improvement methodologies like Six Sigma and Total Quality Deming to the quality improvement in all areas of an organization (a philosophy known as Total Quality Management, or TQM).

Control charts show the performance of a process from two points of view. First, they show a snapshot of the process at the moment data is collected. Second, they show the process trend as time progresses. Process trends are important because they help in identifying the out of control status if it actually exists.
With help of control chart, it is possible to find out natural capability of a production. Can every company use Total Quality Management (TQM) or is it just
4 May 2015 1. A control chart indicates whether a process is in control or out of control. 2. It determines processes variability and detects unusual variations

Process trends are important because they help in identifying the out of control status if it actually exists. Control chart. Control chart is also called as Shewhart Chart named after Walter A. Shewhart is basically a statistical chart which helps in determining if an industrial process is within control and capable to meet the customer defined specification limits. What are control charts? A control chart is a popular statistical tool for monitoring and improving quality. Originated by Walter Shewhart in 1924 for the manufacturing environment, it was later extended by W. Edward Deming to the quality improvement in all areas of an organization (a philosophy known as Total Quality Management, or TQM). Control Charts: Everything You Need To Know Control charts have long been used in manufacturing, stock trading algorithms, and process improvement methodologies like Six Sigma and Total Quality Management (TQM). The purpose of a control chart is to set upper and lower bounds of acceptable performance given normal variation. Quality control charts are used to determine whether a process is stable over time. In project management, one of the uses of control charts is to keep a track on the Cost Performance Index (CPI) and Schedule Performance Index (SPI). In this article, we’ll use CPI as an example to understand and interpret a quality control chart. Variation is inherent in nature. Production of two parts can nor not be exactly same. Variations are bound to be there. Variations are due to assignable cause, due to chance cause. Assignable cause- It is attributed towards,- Difference in machine
