Six Sigma projects are based on 2 project methodologies that take inspiration from Deming’s Plan Do Check Act Cycle. All these methodologies in six sigma certification and training are broken each into 5 phases and have the acronyms DMADV and DMAIC. The following guide sheds light on more six sigma information based on these methodologies.
DMAIC is applied to projects focused on inventing an existing business process. On the other hand DMADV applies to projects that create new process and produce designs. As already mentioned, these two six sigma certification and training have 5 phases each. The first phase has the following functions — defining the system, customer voice and requirements, and the goals of the project. The second phase involves measuring the key aspects of the process and collection of relevant data.
The third phase in DMAIC analyzes the data for investigating and verifying cause and effect relationships. It will focus on finding out what the relationships are and makes sure that all the factors have been taken into account. This also involves finding out the main cause behind the defect. The fourth phase involves the improvement and optimization of the current process based upon more six sigma information such as data analysis through mistake proofing and experimentation for creating better processes. Pilot runs are created for establishing process capabilities.
The fifth phase involves controlling the future state process for ensuring that any variations from the target get rectified before any defects are caused. It will deploy control systems like statistical process control, visual workplaces, production board and regularly monitor the process. Beyond these 5 phases, some organizations could create a Recognize phase at the initial stage of six sigma certification and training. It involves recognizing the problem to work on which creates the RDMAIC methodology.
The DMADV methodology is also referred to as Design For Six Sigma (DFSS) and it has 5 phases too. The first phase defines design goals which are consistent with the organization’s strategy and customer demands. The next phase involves measuring and identifying CTQs s(points Critical to Quality), production process capabilities, risks and product capabilities. The third phase involves analysis for developing and designing alternatives. The fourth phase involves the designing of better alternative, suited ideally to the analysis carried out in the previous phase for more six sigma information. The fifth phase verifies the design, creates any pilot runs and implements the product process before handing it over to the owner.
Six Sigma involves the use of many quality management tools and techniques. During the 5 phases, six sigma certification and training uses a number of quality management tools and techniques which are used beyond 6 sigma. In many universities in the US offering Industrial Engineering, many of these methods are included in the courses. These are the most important methodologies and phases in Six Sigma that can define the success of an organization. Before you choose any programme to complete your 6 Sigma training, make sure that the course includes all these phases.
