2.1. THE 'DMAIC ' FRAMEWORK : The principle problem solving methodology used by six sigma is DMAIC -- Define, Measure, Analyze, Improve and Control. This is one of the first things that a Greenbelt in training learns (Evans, Lindsay ,8th edition 2012). And also DMAIC is the cyclic process as shown in the figure 2.
2.1.1. DEFINE: The first step is to clearly define the problem. The define is the first phase of the lean six sigma improvement process. in this phase the leaders of the project charter, create a high level view of the process, and begin to understand the needs of the customers of the process. A good problem statement should also identify customers and the CTQs (Critical To Quality) that have the most impact on product or service performance, describe the current level of the performance or the nature of errors or customer complaints (Evans, Lindsay ,8th edition 2012).

This includes elements such as value stream mapping, lean workplace, process improvement (KAIZEN), visualization and standardization of processes, processes of quality assurance at source, manufacturing cells, total productive maintenance, fast casting equipment, teamwork and more (Kucerova, Mlkva, Ruksova, 2013). Lean manufacturing is so concentrated on the elimination of waste in any part of the production (Pettersen, J., 2009). Starting by contacting the customer and accepting his demands, continuing through the supply network, manufacturing process and ending with selling the finished product to the customer, flexibly and economically but at the same time respecting the customers’ needs.
