Quality Control Charts were developed in which decade?

Quality Control Charts were developed in the mid-1920s by Walter A. Shewhart. He introduced these charts as a statistical tool for understanding process variability and maintaining quality in manufacturing. The use of these charts allows organizations to visually monitor process performance over time, helping identify trends, shifts, and potential issues before they lead to defects or failures.

The establishment of Quality Control Charts during this time marked a significant advancement in quality management, laying the groundwork for later developments in statistical quality control and total quality management practices. This early 20th-century innovation was pivotal in the evolution of quality assurance techniques that are still relevant in different industries today.
