Lean and Six Sigma
Today while researching I realised that the main difference between lean and six sigma is that one focuses on the process route while the other focusses on a specific part of the business or process to reduce variation. The main aim for both is to reduce variation. If both are combined it can be a very useful tool to fight variation in the process.
Lean works on redesigning the process while six sigma works on a part of the business. Different methods used i lean are cell manufaturing, just in time.......while in six sigma one uses the dmaic cycle and so on.
