When six sigma not success?

Six Sigma may not succeed when there is a lack of commitment from leadership or insufficient training and understanding among team members. Cultural resistance to change can also hinder its implementation, as employees may be skeptical or unwilling to adopt new processes. Additionally, if the organization's goals are unclear or if the focus is solely on short-term gains rather than long-term quality improvements, Six Sigma initiatives are likely to falter. Lastly, inadequate data collection and analysis can lead to misguided decisions and ineffective solutions.
