The main difference between Lean and Six Sigma when it comes to their approach to process improvement is firstly that lean focuses on reducing the amount of time it takes to perform the product with that method and then focusing on process improvement by eliminating waste and getting this time as efficient as possible. Lean also takes customer wants and needs into consideration. In contrast with Six Sigma where they don't just want to improve the process, they use statistics and data to aim to achieve perfection in output with no defects. 2. Explain what you think are the two most important Lean tools? Why do you think this way? I think the two most important lean tools are Kanban and Just In Time. I have chosen these based on my personal experience and the industry I have worked in. Just in time is a great tool that we used on construction projects to plan to get materials to the site at the time needed. Most sites don't have the room to have materials sit there, and it also means that all cost outlays are not at one time. I personally also like using KanBan. I am a very visual learner and I feel it helps me organise workload and thoughts. The short succinct presentations are also useful for my industry which is extremely fast paces and you need to be considered and to the point. ------------------------------------------------------------------ 1. What are the main differences between Lean and Six Sigma approaches to process improvement? The main difference between Lean and Six Sigma is that Lean is focused on quality improvement and providing maximum customer value by eliminating waste and making processes more efficient while Six Sigma is focused on reducing variation in the processes by reducing defects and maintaining more consistent processes. 2. Explain what you think are the two most important Lean tools? Why do you think this way? In my view, Kanban and value stream mapping are two important Lean tools. Kanban creates a balance between demand and supply, thus helping eliminate waste by managing inventory and resources more efficiently. Value stream mapping provides visualization of process, enabling the viewer to understand the current process, highlight any problems and develop solutions for those problems. The visual representation of all items in a process help identify all potential risks, thus allowing better risk mitigation and problem solving.
