Mapping the field: relational study on Six Sigma

This study explores Six Sigma methodology and identifies emerging aspects, trends, and future directions, while also highlighting limitations and unfocused areas in the field.

Six Sigma methodology: a structured review

Six Sigma provides an organizational structure for quality management that enhances process improvement and problem exploration, but also presents new challenges for researchers and practitioners.

Six Sigma: Definition and underlying theory

Six Sigma is a process improvement methodology that uses statistical methods to enhance product and service quality, with a historical perspective and impact on industry practice.

An Overview of Six Sigma

Six Sigma has potential and limitations, particularly in a knowledge-based environment, and should be considered carefully when evaluating its appropriateness for organizations.

A strategic assessment of six sigma

Six sigma can improve service process performance and reduce costs, but its implementation in service organizations requires key success factors and project selection.

Six sigma for service processes

This paper identifies 12 major themes of criticisms on Six Sigma and offers 16 research directions to improve understanding and implementation of Six Sigma as a business improvement strategy.

Key Criticisms of Six Sigma: A Systematic Literature Review

Six Sigma methodology aims to reduce defects and improve yield, leading to cost reduction and customer satisfaction, but it is best used in conjunction with other quality standards.

Six Sigma: concepts, tools, and applications

Six Sigma research primarily focuses on business and management, with Lean Six Sigma becoming a popular term, and further survey studies are needed for advancement in the field.

Six Sigma literature: a bibliometric analysis

Six Sigma is a business strategy that uses financial measures to identify projects for improvement and ascertain results, requiring managers to become more literate in statistics and communicate it in a usable format.

Six Sigma: The Breakthrough Management Strategy Revolutionizing the World's Top Corporations

This paper explores Six Sigma from a goal-theoretic perspective, suggesting propositions for future research and laying the groundwork for scientific knowledge about the phenomenon.

Six sigma: A goal-theoretic perspective

Six Sigma practices, such as role structure, structured improvement procedure, and focus on metrics, are distinct from traditional quality management practices and complement them in improving performance in manufacturing plants.

The evolving theory of quality management: The role of Six Sigma

Six sigma benefits organizations by refining organizational culture, but requires time and commitment for strong implanting.

Benefits, obstacles, and future of six sigma approach

Six Sigma concepts in software engineering are derived from total quality management, but its exact meaning and application remain unclear.
