Kaizen is the Japanese term for continuous improvement. In manufacturing, it means making small, incremental improvements to processes, products, and the work environment — every day, at every level of the organization. The philosophy holds that 1,000 small improvements are more valuable than one large one.
Key distinction: Kaizen is not a project — it is a management philosophy. It does not require capital investment. It requires a system that surfaces problems, captures improvement ideas, and closes the loop on implementation.
The PDCA Cycle — Kaizen's Engine
△ Plan-Do-Check-Act (PDCA)
▶ Plan
Identify the problem using data. Define the expected improvement. Establish a baseline measurement. Design the change.
▶ Do
Implement the change — typically on a pilot basis first. Collect data during the implementation. Document what was done and any unexpected findings.
▶ Check
Compare results to the baseline. Did the change produce the expected improvement? TaktClock's Trends tab provides before/after cycle time comparison.
▶ Act
Standardize the improvement if it worked. If it didn't, return to Plan with new information. Then identify the next improvement opportunity and repeat.

❓ Knowledge Check
A kaizen action relocates a tool to a shadow board at a specific workstation. After one week, TaktClock's Yamazumi shows that subprocess cycle time improved by 12%. What is the next PDCA step?
✓ Correct! Act means standardizing what worked. The shadow board improved one workstation by 12% — now replicate that standard to all similar workstations so the gain is captured everywhere, then start the PDCA cycle again for the next improvement opportunity.
