Quiz: Basic Quality Concepts

  1. What is the difference between quality control and quality assurance?

Quality control (QC) is the process of inspecting and testing products to ensure that they meet the specified requirements. Quality assurance (QA) is the overall process of planning, implementing, and monitoring activities to ensure that products and services meet the required quality standards. In short, QC is focused on conformance to requirements, while QA is focused on the overall quality system.

  1. What is the purpose of statistical process control?

Statistical process control (SPC) is a method of monitoring and controlling a process using statistical techniques to analyze the data. The purpose of SPC is to identify and correct process variations to improve the overall quality of the product or service.

  1. What is Total Quality Management (TQM)?

Total Quality Management (TQM) is a management approach that seeks to optimize an organization’s overall quality by involving all employees in the quality improvement process. TQM is based on the principles of customer focus, continuous improvement, and the involvement of all employees in the quality management process.

  1. What is ISO 9001?

ISO 9001 is an international standard that sets out the requirements for a quality management system (QMS). It is designed to help organizations consistently meet customer requirements and improve overall performance. Organizations that meet the ISO 9001 are awarded certification, demonstrating their commitment to quality.

  1. What is Six Sigma?

Six Sigma is a quality management approach that seeks to improve the quality of a process by identifying and removing the causes of defects and minimizing variability in the process. Six Sigma is based on a set of tools and techniques, such as statistical process control and the design of experiments, that are used to analyze and improve processes.

  1. What is the difference between a control chart and a histogram?

A control chart is a graph that is used to monitor a process over time, while a histogram is a graph that shows the distribution of data. A control chart typically displays data in a line graph with upper and lower control limits, while a histogram shows the data distribution as a bar graph.

  1. What is the process of root cause analysis?

Root cause analysis is a process of identifying the underlying cause of a problem or defect. It is used to identify the root cause of an issue so that it can be corrected and to prevent a recurrence. Root cause analysis typically involves a systematic approach, such as the 5 Whys or Fishbone diagram, to help identify the root cause.
