What do both Six Sigma and Lean focus heavily on?

Six Sigma and Lean methodologies both place a strong emphasis on satisfying customers. This focus is foundational to their principles and practices because the ultimate goal of any improvement initiative is to meet or exceed customer expectations. Satisfied customers are essential for a business's success, and both methodologies aim to enhance the quality of products and services that customers receive.

In Lean, the emphasis is on eliminating waste and improving efficiency, which in turn contributes to delivering greater value to customers. This ensures that the processes are streamlined to meet customer needs without unnecessary steps or delays.

Six Sigma focuses on reducing variability and defects in processes, which leads to higher quality outputs. By improving quality, organizations can ensure that customer requirements are consistently met, which directly correlates with customer satisfaction.

Though other options may have relevance in a corporate environment, customer satisfaction stands out as a shared core focus of both Lean and Six Sigma, guiding organizations to adopt practices that ultimately resonate with and benefit their customers.
