What are the advantages and disadvantages of PDCA?

The PDCA (Plan-Do-Check-Act) cycle offers several advantages, including a structured approach to continuous improvement, fostering team collaboration, and promoting data-driven decision-making. However, its disadvantages include potential time consumption in each cycle, the risk of over-analysis leading to stagnation, and the necessity for a cultural shift in organizations that may be resistant to change. Additionally, if not implemented correctly, it can lead to incomplete or ineffective improvements.
