Six Sigma Analysis

Six Sigma analysis is one of the most important parts of the entire process. There are various types of analysis methods and tools which are case specific and should be applied according to the requirement of the company. Some of the analysis methods are solely meant for the black belts and some are also available for the green belts. DMAIC and DMADV models also include Six Sigma analysis as an inevitable part.

Whenever Six Sigma is implemented in a system, the analysis parts become very important. Be it data analysis or simply analyzing the scopes of improvements; they are equally vital for the system to be effective. There are two most important models of Six Sigma- DMAIC and DMADV. In both of these methodologies Analysis is the inevitable part that is used to evaluate the existing system and the scopes of improvement as well as the risks of implementing certain strategies. Analysis is one step, on which the success of the entire system depends.

The green belts, black belts and the master black belts; all of them need to go through the analysis process according to their process requirements. During the certification courses, analysis capacity of the employees is enhanced by regularly practicing the real life troubleshooting methods. Now, there are numerous methods that are used regularly for analyzing situations.

    • The Root Cause Analysis Method:  the root cause analysis method is used by most of the large, medium and small businesses. This is an in-depth approach towards problem solving, which comes up with permanent solutions for any kind of critical business condition. All aspects of the business are considered and analyzed in order to reach the root of the causes that created the problem. This is not a quick-fix solution but a long term resolution for the problems. The Root cause analysis method involves few steps and is slightly lengthy. But when you calculate the benefits, there is no reason to regret.
  • Failure Mode and Effect Analysis (FMEA): FMEA is one of the most effective and time-tested method of analysis performed in Six Sigma. Using this particular method, the Six Sigma specialists organize all the contributions of a team and then detect the errors occurring repeatedly in those inputs. This way the major risk factors are identified with the help of analysis. Now it becomes easy to eliminate those defects and work on the risks based on the priorities. The crucial ones are eliminated first and rest later. This particular analysis is quite helpful in the systematic improvement of an organization.
  • Kano Analysis: This particular analysis method was developed by a professor from Japan, Mr. Noriaki Kano, with the assistance of his peers. This theory of analysis states that the satisfaction level of the customers is almost proportional to the service that is already into function. This particular analysis method is really helpful when it comes to understanding the real needs of the customers. Kano analysis helps the organizations to provide better quality services and products to their customers which are directly related to the success of the companies.
  • Value Stream Analysis: Value stream analysis is meant for the black belts. Though they are pretty much aware of their responsibilities and all strategies of Six Sigma, this type of analysis helps them implement the projects in a better way. They need to execute this analysis carefully as all the business processes are different from one other. Proper identification and classification of the problems is essential for the analysis to be correct. So, extra effort and caution will definitely help the black belts to carry out the value stream analysis rightly.
