[-AI-3.5]Is Six sigma still more useful than AI for quality improvement in 21st century?

Abstract

21世紀において、製造業の品質を改善するのにシックスシグマはどの程度有用であるのだろうか。我々の生活は急速に進化するテクノロジーに支配されており、その環境下ではシックスシグマが機能しているかどうかは疑問である。シックスシグマは、1980年代にモトローラによって開発され、1995年にジェネラル・エレクトリックによって採用された品質管理の戦略である。その目的は、製造プロセスの改善を通じて欠陥を減らすことであり、シックスシグマによる欠陥率は100万あたり3.4未満を目指す。シックスシグマのプロセスは、DMAIC（定義、測定、分析、改善、制御）と呼ばれる5つの段階で構成され、品質問題を特定・分析し、変更を実施するための具体的な手法が用意されている。シックスシグマは、企業内での品質文化の向上を促進し、顧客満足度を向上させ、より良い製品やサービスを提供し、ビジネスの成長を後押しすることを目指している。

一方、21世紀の製造業における品質改善にはいくつかの課題がある。例えば、AIの急速な進展により、製品設計の複雑さが増している。また、高度な技術の出現も著しい。しかし、製造業の根本的な問題は顧客ニーズへの迅速な対応である。現代社会では、消費者は製品品質に対する要求が高く、企業が顧客ニーズを満たせなければ生き残ることはできない。シックスシグマは、継続的な品質改善を提供できるが、製造業にとって十分な解決策ではない。これは、シックスシグマのアプローチが限られており、新しい技術に適応することができないためである。製造業には、より革新的で適応性のある解決策が求められている。

Introduction.

In the present 21st century, how useful is Six Sigma in improving the quality of the manufacturing industry? Our lives are dominated by rapidly evolving technology. In this environment, it is really questionable whether Six Sigma is working as it looks.

What is Six Sigma?

Six Sigma is a strategy to improve quality control, developed by Motorola in the 1980s and adopted by General Electric in 1995. Based on a mathematical structure, its aim is to reduce defects through improvements in the manufacturing process. The defect rate targeted by Six Sigma is less than 3.4 per million. The goal of this strategy is to increase the level of quality and reduce defects. The Six Sigma process consists of five stages called DMAIC (Define, Measure, Analyze, Improve, Control). These stages include specific methods to identify and analyze quality issues and implement changes. Six Sigma aims to promote a culture of quality within organizations to improve customer satisfaction, provide better products and services, and promote business growth. Therefore, it remains an important strategy in the 21st century.

Challenges of Quality Improvement in the 21st Century.

In the 21st century manufacturing industry, there are several challenges for quality improvement. For example, the rapid progress of AI is increasing the complexity of product design. With this, the emergence of advanced technology is also becoming remarkable. However, the fundamental problem in the manufacturing industry is the rapid response to customer needs. In modern society, consumers have high demands for product quality, and if companies cannot meet customer needs, they cannot survive.

Six Sigma can provide continuous quality improvement, but it is not a sufficient solution for the manufacturing industry. This is because Six Sigma’s approach is limited and cannot adapt to new technology. The manufacturing industry needs more innovative and adaptable solutions. In the next section, we will take a closer look at the comparison between quality improvement with AI and Six Sigma.

The limit of Six Sigma.

Six Sigma achieved explosive success in the manufacturing industry of the 20th century. However, as manufacturing technology and market needs rapidly change in the 21st century, the usefulness of Six Sigma has also reached its limits. There are several reasons for this. First, Six Sigma is a very strict method and adaptation to new technologies and styles is slow. In addition, in modern business, quality improvement is demanded in various operations, so the scope of Six Sigma’s application is also limited.

Furthermore, Six Sigma does not value creativity or innovation, so it cannot respond to new market needs. This is an essential element for the contemporary business world. Therefore, applying Six Sigma can also lead to setting limits for success.

Based on these reasons, doubts have arisen as to whether Six Sigma is still more useful in the 21st century manufacturing industry than AI. In particular, AI is more innovative, efficient, and capable of rapid quality management than Six Sigma. However, AI cannot solve all problems and must be used under appropriate case studies.

Therefore, it can be said that it is essential for future business success to understand the limitations of Six Sigma and combine it with new technologies.

Comparison of Quality Improvement by AI and Six Sigma.

AI-based quality management offers many benefits. Specifically, AI-based quality management can accurately manage quality through automated data collection and analysis, more accurately than Six Sigma. Additionally, AI has the advantage of being able to perform inspections very quickly and precisely.

On the other hand, when comparing AI-based quality management with Six Sigma, Six Sigma is a relatively simple method and can be introduced in many companies. In the case of AI, many technical skills are required to build the system, and it may not be easy to adopt. Regardless, as the level of AI technology advances, it is expected to be adopted by more and more companies.

Appropriate Use of AI as a Case Study:

AI-based quality management is being implemented in various industries. For example, one manufacturer has built a system that automatically detects product defects with AI and automatically stops equipment on the production line. Additionally, a service provider has used AI to categorize inbound inquiry contents to the call center automatically.

The future of Six Sigma.

Six Sigma was a powerful tool for achieving quality improvement. However, the progress of modern innovation and technology has raised doubts about the value of this methodology.

To reform Six Sigma and leverage its strengths, the following are necessary. Firstly, a new agile mindset is required, enabling swift responses to changes in the market. Secondly, flexibility is needed as new methodologies may emerge with technological advancements. Therefore, Six Sigma needs to be reformed to adapt to new technologies.

For Six Sigma to be successful, a new direction is needed. Research has shown that Six Sigma is suitable for the manufacturing industry. However, there are increasing opportunities for its use in other sectors such as the service industry and software development. In today’s business world, Six Sigma needs business-oriented adjustments to hold greater value.

The world ahead will be dominated by innovation combining technology and creativity. Six Sigma needs to comprehend this and prove its continued usefulness as a methodology.

Conclusion.

Six Sigma is an outdated methodology and cannot keep up with the quality improvement achieved through modern advanced technology. The progress of AI is faster and Six Sigma needs reforms to penetrate its application.
