Special Causes of Variation are also known as Assignable Causes (un natural) of variation. If Special cause of variations are present in a process, then the voice of the process is neither stable nor predictable and is said to be out of statistical control. SPC technique uses Control Charts to monitor and control the Special […]

Variation is the basic principle of Statistical Process Control (SPC). One problem with mother nature is “Variability” i.e. No two things are alike and Everything is different. Variability No two things are alike. The product we produce change continuously. Variation is law of nature and exists in all processes. Variation in a product and process

SPC– Statistical Process Control is used to measure, record, analyze and control the Process Variability for quality improvement. This technique is used to measure Process Capability and controlling quality during the production process. SPC utilizes statistical thinking to control the process and to achieve continuous process improvement. SPC technique is widely applied in the Automotive, Engineering, and

Quality Assurance and Quality Control activities are part of a Quality System or Quality Management System. QA includes QC. QA contains all those planned and systematic actions necessary to provide adequate confidence that a product or service will satisfy/fulfill given requirements for Quality. Quality Control is a set of activities for ensuring quality in the Products. See Differences :

Quality Control is a set of activities for ensuring quality starting from Raw material to finish Products. The activities focus on identifying defects in the actual products produced or during the production process for corrective measures. Therefore, QC is a reactive approach. Quality Control is product-oriented and mainly focuses on quality defect identification and taking

Quality Assurance Purpose Quality Assurance serves the main two purposes – 1. To assure that all is well, e.g the procedures are being followed, the process is performing normally, the product is fit for use.       2. To provide an early warning that all is not well and some corrective action is required. Quality Assurance

“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

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
