SIX SIGMA ANALYZE PHASE

Identifying the issues within the ongoing process of manufacturing is done by the analyze phase of DMAIC. They even check the defects in products. The Six Sigma phase approach contains instruments that provide a helping hand in locating the issues in the manufacturing process. They also confirm whether the issues are mainly responsible for the defects that occurred.

Possible reasons are identified

The data obtained in DMAIC’s measuring phase has the capability to trace out the reasons for defects in the product. Guessing is not a very popular way to detect problems in the traditional Six Sigma process. The following causes can be identified by hosting six sigma tools:

  1. Cause and effect diagram

Fishbone diagram is a distinctive diagram which helps in graphically represent in the reasons of why a problem in production takes place. This representation has two parts. The left parties used by the team working on the project to fill necessary details, and the right side is used to right problems arising in the work environment or product. The whole group of employees working to the left side and also check the possible reasons for the issues such as persons, ways to solve the problem and products.

  1. Map analysis of the project

To get hold of the procedures of the production process, the instrument utilizes a manufacturing process. The whole process is embellished along with the inputs put into the entire process, the tasks that are carried away, the essential decisions that need to be taken along with the outputs. The accuracy of the project called for noting down the whole process of manufacturing, which forced the whole group to think through the way the manufacturing process was operating the present day. A map is designed for the whole project to provide the whole project group, a chance to envisage necessary changes in the project.

  1. Subprocess mapping

A basic map of the whole project is created in the DMAIC layout’s Define phase. The whole process is monitored after that. A large number of the small process together comprise and form these larger processes. The criteria of the subprocess mapping are to draw the smaller subprocesses and keep an account of those. According to the subprocess mapping, the whole group keeps the record of this to get a basic understanding of the way to make larger and smaller processes work and interrelate with each other. A clear visual of the method of production is gained by this, and the team also becomes capable of rectifying possible issues.

Discovering the main reason

After finding a feasible reason, the whole staff working on the project has to verify whether the reason found is the correct reason for the problem or not. Numerous instruments are used by Six Sigma practices to help to check the conjecture that a simple jerk in the manufacturing method is the main reason for the deficiency of the product.

Regression Analysis

The following instrument measures the changeable effect the whole method has on each other, and even its impacts on the final product are checked. The whole group working on the project is allowed to estimate the way the theory settles the information.

ANOVA

The following analytical procedure thoroughly checks three or even more sets of information. The procedure begins with an invalid theory stating that there doesn’t lie any remarkable difference between the teams. Then, the difference between various groups of information is then marked along with the difference between the information inside the groups.

Chi-Square

Observational tools for processing and forming subjective theories define the dual nature of Six Sigma. The project team uses process maps like fishbone diagrams to analyze the project management process.

The possible causes are deemed to be the reason for product defects, which is found out by rigorous mathematical calculations and operations through the Chi-square techniques and regression analysis. After forcing strict checking on the mathematical thoroughness of the analysis, the procedures of Chi-Square check whether the following reasons are the actual cause behind the flaws in the products that were manufactured.

Listed above are all the necessary information about the techniques that help in analyzing of Six Sigma. A piece of brief information is also provided about the analysis phase of Six Sigma. This phase of Six Sigma practices contains necessary instruments that locate the problems as well as find the main cause behind the problem. A lot of methods and methodologies are involved in the analysis phase of Six Sigma.
