Six Sigma Green Belt lean management

The Six Sigma approach is a flexible and comprehensible system for achieving and sustaining business success. The system is focused on the profound knowledge of customer requirements, on improving the quality of products and minimizing the costs. Six Sigma is an innovative managerial concept firstly developed by Motorola in 1986, introducing a set of quality standards for daily work. Although the Six Sigma originated as a set of practices designed to improve manufacturing processes and eliminate defects, its application was subsequently extended.

The Six Sigma approach has a very well-defined structure known as the DMAIC project methodology and creates an array of expert professionals in these fields forming the belt personnel. The Green Belts are placed in the medium level of the hierarchical scale and are expected to assist the higher in rank Black Belts. They have less responsibility than the Black Belt professionals and direct their efforts towards projects that tie to their regular work.

If you have Yellow Belt training it means you are already familiar with the basic concepts of Six Sigma and the most commonly used tools to implement it within a company. Therefore you should consider advancing to the next level in your training. Nowadays there is a growing demand of specialists in both Lean Manufacturing and Six Sigma principles, so if you want to become an appreciated Green Belt you should include Lean philosophy in your training. The fundamental philosophy of Lean is defining the concept of „value” for customers. Consequently, all the activities that don’t create value for them (but instead they only generate costs) can be detected and called „wastes”. The Lean is not focused on individual processes; it improves the entire value stream (all the processes needed for bringing the product from raw materials into the hands of the customers). The sole purpose of Lean is to reduce and remove wastes from the value stream.

The Lean Six Sigma methodology can be applied in the production activity and the service industry alike, whether or not we are talking about speeding up the processes, bettering their outputs or cost reductions. Lean Six Sigma thinking provides an entire set of tools than can be used to decrease costs, increase productivity and the quality of the provided products and services, as well as heightening customer satisfaction. If you can blend the lean management philosophy with the Six Sigma approach you will definitely yield your abilities to carry out almost any DMAIC project and solve the arisen problems. All this being considered, the more you know on Six Sigma and lean management, the more capable you will be to conduct improvement projects that will generate the positive effect you desire over your company.

If you want to become a Green Belt you will be required to cover several topics, beginning with a solid knowledge on the improvement tools and concepts related to a process. Secondly, you will need to have basic notions on the design of experiments and handle the statistical process control. Furthermore, you should be familiar with root cause analysis and problem solving issues. Also, FMEA is extremely important because in every project you need to handle things with caution and try not to overlook what may go wrong. You should make good use of the past experience and help your team to identify potential failures and their consequences on the good progress of your activity. It is always advisable to spot them in an early stage for reducing the effort and expenses necessary to fix the problem. These would be the most important aspects required to achieve the Green Belt certification that will boost your resume.
