The focus of six sigma is to enhance process control and reduce process variation. More often than not, the term ‘lean six sigma’ is used because, for process improvement, both approaches are used for attaining positive results. There is no significant difference between lean and six sigma. It also includes encouraging the process of development and customer discovery and iterating for achieving the right market fit or product. Lean is another methodology that focuses on starting up the process emphasizing on the business model over the business plan. The quality performance according to six sigma is 3.4 defects per million products or services. There are other six sigma methodology but DMAIC is the most recognized and adopted. This includes identification of the problem and implementing a long-lasting solution. It involves defining the steps a practitioner must follow. In this view of six sigma, there is recognition of the rigorous and underlying approach named as DMAIC. Although, no specific set of tools have been selected as the tools for six sigma. These tools include process mapping, control charts, statistical process control (SPC), and failure mode and effects analysis (FMEA). Toolsįor implementing the six sigma approach, certain tools or quantitative and qualitative techniques are required for driving process improvement. To control the outputs, you need to control the inputs. For the processes, you require inputs (x) which will produce outputs (y). Six Sigma defines all the work as processes that follow the DMAIC approach of defining, measuring, analyzing, improving, and controlling. We then examine the success factors involved while introducing the Six Sigma methodology and what you can do to enhance your career prospects in Six Sigma. We introduce the philosophy, the tools, the methodology and the metrics and then dive deeper into how Lean and Six Sigma complement each other by understanding their key elements and principles. In this article, we will provide you with a brief overview of the Six Sigma methodology. Creating a management environment supporting the initiatives as a business strategy.Emphasizing on the DMAIC approach for solving problems.Training people of all levels in statistical thinking and providing extensive training in project management and advanced statistics to key people. ![]() Using teams that have been assigned well-defined projects and can directly impact the bottom line of the organization.There have been different definitions proposed for Six Sigma with the following common threads: It leads to a decrease in process variation and increase in performance helping in reducing defects and improving employee morale, profits, and quality of services or products. Six Sigma is a methodology providing the organization with the tools to improve the quality of business processes.
