The practice of continuous improvement in quality management is known as:

1. Six Sigma

2. Kaizen

3. TQM

4. All of the above

The correct answer is: All of the above

The concept of continuous improvement in quality management is best encapsulated by the term Kaizen. Kaizen is a Japanese term that translates to "continuous improvement" and emphasizes small, incremental changes to improve efficiency, quality, and overall operations within an organization. While Six Sigma and Total Quality Management (TQM) are also frameworks that focus on quality and process improvement, each has its unique approach. Six Sigma is a data-driven methodology that aims to reduce defects and variability in processes to enhance outcomes, and TQM focuses on long-term success through customer satisfaction and involves all members of an organization in improving processes, products, services, and the culture in which they work. Choosing "all of the above" highlights the interconnectedness of these methodologies. Each method incorporates aspects of continuous improvement, but Kaizen specifically symbolizes the practice of making ongoing small changes to improve quality. Each approach has merit and can be used in conjunction with others, which leads to the understanding that they can collectively contribute to a culture of continuous improvement.
