Which strategy focuses on small, ongoing improvements that lead to significant changes over time?

The strategy that focuses on small, ongoing improvements leading to significant changes over time is Kaizen. This approach is rooted in the philosophy of continuous improvement and is often employed in manufacturing and business processes. Kaizen promotes the idea that small, incremental changes can accumulate to produce substantial enhancements in efficiency and quality. By involving all employees in the process of identifying areas for improvement and empowering them to suggest and implement changes, organizations can foster a culture of continuous learning and adaptation.

This contrasts with other strategies such as Six Sigma, which aims for reduction in defects and variation within processes using statistical methods, and Agile Development, which focuses on iterative development and customer feedback in project management. KPI Management, on the other hand, centers on measuring and analyzing performance indicators rather than on the process of continuous incremental improvement itself.
