Six Sigma Methodology
Six Sigma Methodology was developed on Shewart’s statistical control philosophy and based off of process capability studies. The Greek symbol sigma (σ) stands for variability. The purpose for the Six Sigma Methodology is to reduce the amount of variation in process or performance. There are two main types of Six Sigma methodologies, DMAIC and DMADV
(VILLA).
Motorola was the first company to utilize the Six Sigma. This started in the mid1980s.
Motorola wanted to use this to improve the quality of their production by reducing the number of defects. For the company to implement Six Sigma, the number of defected parts had to fall within the range of 3.4 defects per 1 million opportunities (Spath, 2013). Once Motorola

In this essay, the author

  • Describes the steps that would be taken to implement a variation control and manage the improvement process.

  • Explains the purpose of the six sigma methodology is to reduce the amount of variation in process.
  • Explains that motorola was the first company to utilize six sigma to improve the quality of their production by reducing the number of defects.
  • Explains the process of utilizing six sigma to improve a process or product that is already existing.
  • Explains that the second method is dmadv, which follows the same steps at dmacic, but is used to develop a completely new process or product (villa).
  • Explains that the data collection and analysis part of the phase helps determine a design that will get the product or process within the six sigma standard. once the design is complete, testing must be done to confirm that everything is running properly.
  • Explains that while some may say that six sigma is the best way to grow a business, there are some that actually think it will do more harm than good when looking at the bigger picture.

  • Explains that following these guidelines will give a business measurable goals that can be supported by statistics gathered from every aspect of the company.

After this is all finished, the data collection and analysis part of the phase comes into play. Using that data and the summary of the collection will help you determine a design that will get the product or process within the Six Sigma standard.
Once the design is complete, testing must be done to confirm that everything is running properly and it will result in the perfect implementation of the methodology. The goal is to create a process or product right off the bat that falls within the parameters. Doing this will lead to cost reduction, value creation, and less refurbished products (Saxena, (n.d.)).

Fully embracing Six Sigma will require a business to eliminate variance and experimentation that will cause a loss, but this will inevitably cause the business to lose its ability to grow and thrive in the future.
There is no question that the Six Sigma Methodology is very successful in enhancing the process quality of a business. Adopting this approach and adapting it to your current business model will no doubt increase efficiency, but there is a fine balance of growing today yet being innovative in the future. The steps involved in either of the two methods have a certain level of personalization to allow businesses to customize the methods to focus on today and tomorrow.
Six Sigma has been around for nearly 3 decades and continues to be one of the leading and fundamentally sound ways of running a business more efficiently. It removes all the guesswork and allows the statistics and data to steer your business decisions in the right direction. By following these guidelines, it will give a business measurable goals that can be supported by statistics gathered from every aspect of the company, from the customer all the way up to the very top.
