What Is Six Sigma?

Six Sigma is a standardized approach for eradicating errors. Six Sigma uses statistical methods to promote the quality by reducing variability in business processes, from manufacturing to engineering and buying. Six Sigma achieves its goal by using two Six Sigma Methods: DMAIC and DMADV.

Six Sigma DMAIC

In SKIL the Six Sigma DMAIC way is typically used to enhance an existing process. DMAIC is a phrase that stands for:

  • Define the problem and expected outcome
  • Measure the competence of the procedures
  • Analyze the data and analyze the root principle of variations (errors)
  • Improve or customize the process so that fewer variations (errors) are made
  • Control the process. Prohibit and correct variations before they result in errors

Six Sigma DMADV

Designing new procedures in SKIL, the Six Sigma DMADV is used. It is also called as DFSS (Design for Six Sigma). The DMADV phrase stands for:

  • Define design standards that adjusts with the product or process aims
  • Measure and identify aspects of the product or process that are demanding to quality
  • Analyze the data, and analyze possible sources of errors
  • Design changes that will eradicate the source of bugs or errors
  • Verify that the design will reach the requirements

Main Key for Six Sigma Principles

Six Sigma successes are mainly based on these key principles:

  • Targets on customer requirements
  • Using comprehensive measurement and statistical analysis to explain how work gets done and to identify the root cause of issues (variations)
  • Being proactive in eradicating variation and continually enhancing the process
  • Associating people in Six Sigma cross-functional teams
  • Being thorough and being extensible


Six Sigma is about enhancing quality. The first step in that process is explaining what “quality” means, from the aspects of the people whose assessments matter most: the customers


After analyzing root causes, make changes to the process that will eradicate variation, and thus eliminate errors from the process. Collect data, talk with people, and study the data to check variations in the process that may have become popular.


Six Sigma comprises teams and leaders who take responsibility for the Six Sigma processes. The people on the teams required to be trained in Six Sigma's methods, consist of the Six Sigma measurement methods and development tools that will be used.


Six Sigma needs flexibility in various ways. The business’s management system wants to accept positive changes as well as allow changes. Employees should be motivated to modify the changes in Six Sigma Quality Management Tools includes of a variety of tools can be used to support Six Sigma, including Value Stream Mapping (VSM), Capability Analysis, 5 Whys, Plan-Do-Check-Act (PDCA), and Statistical Process Control (SPC).

At SKIL, Six Sigma methodologies are pretty much clear, visual and effective communication that involves changes and requires effective on-going communication. Old habits required being broken and new habits are fixed. Graphic Products offers an array of supplies that can assist make Six Sigma successful.
