Six Sigma Methodology

Six sigma methodology stands for the basic DMAIC model which is considered to be the basic of the program. DMAIC stands for Define, Measurement, Analysis, Improvement and Control. This is taught to the green belts in detail and often they use this model in practical situations. The black belts also refer to this methodology when required. The target of this methodology is to make improvements in various departments of an organization. There are certain requirements and steps that are necessary for successful implementation of six sigma methodologies. Apart from DMAIC, there are others as well like DMADV and DFSS.

The six sigma methodology helps an organization to make a lot of improvements without many experiments. These are strategies that have proven to be successful over a period of time. It also helps in reducing the risk factors that are always related to the steps you take towards the improvement of an organization but six sigma can be successful only when each and every employee is aware of the facts and intricate details of six sigma strategies. In the basic level of six sigma i.e. green belt certification, DMAIC is discussed thoroughly. As the green belt certified employees of a company are responsible for accomplishing the projects and also leading when required, they need to understand DMAIC completely. They are often observed to refer to the same methods while solving practical problems in the organization. The black belts also use the same DMAIC model to troubleshoot during the projects.

So you can call DMAIC, the most vital and necessary rules of Six Sigma. DMAIC stands for Define, Measurement, Analysis, Improvement and Control. This is considered the main focus of six sigma methodology. This particular model of six sigma methodology was created by Edwards Deming. This model has played an important role in eliminating the error factors from the organizational functions. Following are the steps of DMAIC methodology:

Steps of DMAIC Six Sigma Methodology:

  • Define:  It happens to be the very first step of six sigma methodology. ‘Define’ refers to defining the aims of the project that is being implemented. It depends on the departments where the rules are being implied. When it is all about increasing the outcome of the manufacturing unit or achieving customer satisfaction, there should be a proper definition in front of the team. It acts like an inspiration as well as objective to the members. You can use the method called “data mining” while fixing up the specific goals of the six sigma projects.
  • Measurement: Measurement refers to the process of assessing the pros and cons of the system that is already in use. It is essential to find out the areas where improvement is required. This will allow the leaders to estimate whether the six sigma principles have been implemented successfully or not.
  • Analysis: When you plan to implement a particular six sigma project for the improvement purposes of any department of the organization, you need to do a lot of analysis before that. Make sure the process needs alterations and have the potential to survive the changes you make. It is also important to evaluate if the six sigma implementation for that particular process is worth the cost or not.
  • Improvements: Improvements through the six sigma projects will help the organization to achieve its overall target. The improvement can take place in any department like manufacturing, marketing, customer support or finance. There are numerous tools and applications available in six sigma that aid to achieve the aim of prosperity and growth.
  • Control: This is the last and final step of the entire DMAIC program. With the help of this particular step, the company makes certain the proper improvements and also stops the strategies right at the moment when there is a chance of failure.

Other Six Sigma Methodology:

  • DFSS: DFSS is another six sigma methodology that has certain resemblances with DMAIC. But this strategy focuses more on the innovation and redesigning. It is used to create new products for the business and sometimes refurbishing the existing ones for better yields.
  • DMADV: DMADV stands for “Define”, “Measure”, “Analysis”, “Design”, “Verify”. These strategies are successfully used in various projects by the companies. DMADV methodology has reportedly helped the organizations meet the expectation of their clients.
