A Guide to Certification and Career Paths Lean Six Sigma is all about making customers happy.

It looks at every step of the customer journey, especially the important moments like product performance and customer service. In Six Sigma, the focus is on making sure products work well and don't have defects. This is done by reducing process variations. On the other hand, Lean is about cutting out anything in the process that doesn't add value for the customer, aiming for efficiency and a great user experience. Both Lean and Six Sigma aim to make things better for customers while saving money for businesses. A famous example is the Toyota Production System, which inspired many Lean practices. It's all about designing cars, marketing, and customer service with the customer in mind, getting rid of anything that doesn't benefit them. Simply put, in Lean Six Sigma, if it doesn't make customers happy, it's out! The evolving landscape of the world of business, where the foundation of success lies in providing exceptional customer service, organizations are continually exploring avenues to optimize their processes. As commerce extends its reach both virtually and conventionally, the demand for impeccable customer service has surged. This is where the Six Sigma methodology becomes instrumental, focusing on process improvement and defect reduction to play a pivotal role in transforming customer service into a strategic asset for businesses.
