Six Sigma Black Belt Practice Exam 2026 – Complete Prep Resource

The term that refers to the philosophy of continuous, incremental improvement is Kaizen. This concept is deeply rooted in the practices of Lean manufacturing and emphasizes the importance of ongoing, small enhancements to processes, products, or services over time. The essence of Kaizen is that everyone, from management to the shop floor, is encouraged to contribute ideas that lead to improvements, thereby fostering a culture of quality and efficiency.

Individuals using Kaizen believe that even minor adjustments can cumulatively lead to significant advancements in productivity and quality. This approach contrasts with larger, more disruptive changes that may be associated with philosophies like Kaikaku, which focuses on radical transformation rather than gradual adjustments. Other options like Kanban and JIT (Just-In-Time) are methodologies that support efficient workflow and inventory management but do not specifically embody the concept of continuous incremental improvement expressed in the Kaizen philosophy.
