 Have you ever had to return a product? Chances are you have. Reverse logistics is the supply chain concept that your returns follow. Rather than following a normal supply chain flow the reverse logistics supply chain focuses on improving the reverse flow. The focus of the reverse supply chain is to support customer returns, repair of damaged items, remake or remanufacturing of designs that might not meet the customers expectations and recycling materials. The reverse supply chain can in fact be designed in such a way that it operates at a profit, recovers costs and best of all creates loyal customers. Challenge In the comments section below share some ideas that you have that might help returns be a better experience for customers.

One of the best ways to understand what is going on is to go to the Gemba and see for yourself. This is the central idea behind the term Genchi Genbutsu, which is a core principle in both Lean and Six Sigma.
Genchi Genbutsu (English: Go and see for yourself): The best practice is to go and see the location or process where the problem exists in order to solve that problem more quickly and efficiently. To grasp problems, confirm the facts and analyse root causes. Reference - Toyota Blog Both Lean and Six Sigma require a sound understanding of issues and opportunities before moving forward. Whether management, leadership or shop floor Genchi Genbutsu supports correctly understanding a problem in its entirety before coming up with countermeasures. The nature of the phrase is less about the physical act of visiting a site but more to do with a personal understanding of the full implications of any action within an environment as a whole.  The term yokoten refers to the sharing, learning and teaching of best practices laterally throughout an organization. Yokoten is often referred to as "horizontal deployment" because practice of this principle requires various levels of an organization to share, innovate spread knowledge and or improve on kaizen in a cross functional manner. A very important aspect of this critical principle is that individuals have an opportunity to exercise Genchi Genbutsu and gain consensus on improvements. At times yokoten can include benchmarking, comparing and even borrowing from other improvements, but, in the truest sense yokoten should allow people to develop and grow as a result of sharing, learning and teaching. Challenge One way you can share your expertise and be an example of Yokoten is by adding a term to our community. While we know the glossary is focused on Lean and Six Sigma terms please feel free to add any term you think relates to the philosophies of continuous improvement. Click Below to Add Your Term Today!
