iSixSigma: Six Sigma Resources for Six Sigma Quality
How Starting With a Six Sigma Scorecard Led One Small Company to Significant Increases in On-Time Deliveries, Efficiency, and Profit Within a Year. April 17, 2025. When many think of Six Sigma, they first think of massive corporations utilizing the methodology. Continue reading.
Calculating ROI to Realize Project Value - iSixSigma
How to Calculate ROI The formula for determining ROI is: ROI = [ (Financial value – Project cost) / Project cost] x 100 In looking at the formula, there are two components we need to determine: Financial value and project cost. Financial Value Financial value is simply the project’s payback.

Six Sigma Calculator - Calculate Sigma, DPMO, DPM, Yield, RTY
This sigma calculator can be used to estimate the sigma level of a process (of producing units or delivering a service) based on the ratio of defects it results in. Depending on the input, the output consists of: sigma level of the process (shows how well it is controlled relative to acceptance standard)
Best Buy: Outside of the Box – isixsigma
When Best Buy, headquartered in Richfield, Minn., USA, began implementing Lean Six Sigma in 2005, its focus on creating efficiencies was matched only by its goal to enhance the experience of its end customers. The result: the development of an Enterprise Continuous Improvement Capability Team. Trained Belts identify and solve issues that exist
- What is a Six Sigma calculator?
- The minimum required input is DPMO in which case the six sigma calculator (not to be confused with a sigma notation calculator!) outputs the corresponding sigma level, standard yield and percent defects. Entering the number of defects and total opportunities for a defect to occur outputs the control level (sigma), yield, percent defects and DPMO.
- How much does Six Sigma cost a company?
- According to GE's 1996 annual report, less than Six Sigma quality, i.e., the three-to-four Sigma levels that are average for most U.S. companies, can cost a company as much as 10-15 percent of its revenues. For GE, that would mean $8-12 billion.
- What is a sigma level calculator?
- The sigma level calculator outputs both standard yield: percentage of opportunities which did not produce a defect from the total opportunities present, and its complimentary value - defects percent, as well as defects per million opportunities. These values are important for understanding the overall rate of success of the process.
- What is a sigma level?
- Sigma Level: Organizations determine the sigma levels of given processes (one sigma, six sigma, etc.) as a means of comparing the performance of those processes throughout the entire organization as distinct elements. Sigma process levels 1-6 have a theoretical defect rate that is set as follows: 1 Sigma = 691,462 DPMO, 30.85% defect-free
- How to calculate process sigma rating?
- We must compute the total number of defects, the total number of opportunities, and the defect rate to calculate the process sigma rating. A defect is something beyond the requirements of the customer. The opportunity, on the other hand, is the total number of probabilities for failure.
- What is a sigma rating in Six Sigma?
- Based on the Process Sigma table, the process being implemented by the team only has a sigma rating between 2 to 3. The higher the degree of sigma, the lower the number of defects. Why is Six Sigma Important?
