Before we being the process of explaining the purpose of Six Sigma metrics, we should probably define what metrics are for those who are not familiar with the terminology. Within the Six Sigma Methodology, metrics consist of gathered data that is used to make calculations to produce a quantified analysis of a business process or service that will lead to easily understood process improvement procedures.

Six Sigma data collection is the main event that makes the entire Six Sigma process possible and worthwhile. As such, it is highly important to have very detailed, sophisticated, and consistent tools or methods to help in collecting or gathering the necessary data; not too much and not too little.

The introduction and implementation of the Six Sigma Metrics system to quality, was designed and introduced to Motorola by one of their Engineers in 1986. Within a short four-year period, it was recognized as an industry quality standard and is currently being used by many market leaders throughout the world.

Six Sigma is a quality management process used by organizations to perfect their products and services while decreasing the bottom line.  There are various tools used in this process to accomplish these goals.

When organizations use Six Sigma Tools, they are able to reduce variability and amplify quality in processes.  When using this methodology, it is a designed tool kit for problem solving and quality improvement. 

In Six Sigma, Black and Green Belts will use several different methods in order to improve quality within the DMAIC model. They are usually incorporated into the software that is used by the business owner in order to make it easier for them. Six Sigma tools enable teams to analyze data effectively and design efficient workflows.

Within the models and methods put forth by the DMAIC technique, the Six Sigma flowchart is used as a diagram that helps businesspeople visualize their costs and quality, thereby giving them some indication of what needs to be changed, why, and where in the company those changes need to take place.

The Six Sigma system relies upon mountains of information in order to be able to make any kind of beneficial change with intention. Therefore, it is necessary to use specific tools for collecting the appropriate data. Since not just any information will do, there are guidelines to what information is necessary or beneficial. This information set could be called Six Sigma Data. Collecting Six Sigma data requires proper use of tools and analysis procedures.

Choosing the metrics is a very crucial part of any Six Sigma Project.  Here are some common mistakes to avoid during this process.

There are many statistical tools used within the six sigma methodology to help companies increase the quality of their products and services.  One of these statistical tools is called measurement systems analysis.
