What does the word quality mean? Basically, it means the degree of excellence of something when measured against other things of a similar kind. In workplaces, it is not only about quality but also about quality control. There is a difference.

Quality control refers to the activities that are used to evaluate whether your product or service meets the quality requirements specified for your project, those defined during the quality planning process.

Abbreviated as QC, the modern version of this system relies predominantly on statistical analysis, including the collection, evaluation, and interpretation of data.

Some of the tools and techniques normally used to perform quality control include:

  • Cause and Effect Diagram
  • Control chart
  • Flow Chart
  • Histogram
  • Run Chart
  • Scatter Diagram
  • Statistical Sampling
  • Inspection

These quality controls tools and techniques can help in three ways:

  • Confirm that your project is meeting the quality standards
  • Provide a basis for corrective action
  • Provide feedback about your quality assurance process

Regarding inspection in production, there are three important aspects involved in it:

  • Product inspection – The main purpose is to ensure that the products for sale are free of defects.
  • Process inspection – Is aimed at ensuring that the raw material, machines, and equipment used in the production process are of prescribed quality and mark.
  • Inspection analysis – It enables the entrepreneur to identify the points at which deviations from the standard set start.

Quality control is also a strategic decision because the goal is to control those variables which are encountered in the manufacturing process and which adversely affect the excellence of the final product in one way or another. Some of the important advantages of quality control are as follows:

  • It helps in minimizing the costs by increasing efficiency, standardization, and working conditions.
  • It fosters quality consciousness in employees.
  • Useful to confirm products are manufactured in accordance with the standard set by the Government.

Many people get confused between quality control and quality assurance. Quality control is about the final product while quality assurance deals with the production process.
