The seven management and planning tools are often referred to as the seven new tools.  This set of tools was developed, tested and used by the Japanese Scientists and Engineers (JUSE).  The seven new tools are:

1. The affinity diagram
2. The relationship diagram
3. The tree diagram
4. The matrix diagram
5. The matrix data analysis chart
6. The arrow diagram
7. The process decision program chart

  Regression analysis is a technique that can help us understand the relationship between two variables.  

  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. 

  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.

  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.  

  The waste hierarchy is a common tool used in green and environmentally focused organizations.  The tool helps to rank the different options that you could select when managing waste.  As you can see the highest priority is shown at the top and descends as shown below:

1. Prevention
2. Reuse
3. Recycle
4. Recover
5. Disposal

  In the comments section below list one way you could prevent waste, one way you can reuse some items, one way you could begin recycling and one way you can recover some materials, energy or value from waste.
