Six Sigma Black Belt Certified Practice Exam

The desired change in performance level that is described as "breakthrough" aligns with Juran's philosophy regarding quality improvement projects. In quality management, a breakthrough refers to a significant and sudden improvement in performance metrics or processes that far exceed the current levels. This type of change is essential when aiming for substantial enhancements that can provide competitive advantages and address major issues effectively.

Juran emphasized the importance of breakthrough improvements as part of a structured approach to quality improvement, where efforts are concentrated on achieving substantial impact rather than marginal gains. This is particularly relevant in major projects where large-scale changes and innovations are necessary to achieve desired outcomes.

In contrast, terms like continuous improvement refer to ongoing, incremental enhancements that might not lead to dramatic shifts in performance. Sporadic indicates irregular and inconsistent improvements, which do not align with the focused goals of a major quality initiative. Meanwhile, Six Sigma relates to a specific methodology aimed at reducing defects and improving quality but does not exclusively define the nature of the performance change itself.
