There are many Six Sigma global institutes. As a Six Sigma tool, it is good for establishing upper and lower boundaries to a standard deviation, and to see how a system reacts to variations over time. Control chartĬontrol charts are more visual tools to show us how data changes over time throughout a process. In Six Sigma, this shows what happens to one process and its set of data when changes are made to another. It shows the relationship between two different data sets operating in the same existing process.
Scatter plotĪ scatter plot is another cartesian diagram. In a Six Sigma process, you use the check sheet at the location where the work and its corresponding data collection is taking place. Check sheetĪ check sheet is a form you use to collect and display data. It’s used to see how frequently an event occurs at different stages of a process.
HistogramĪ histogram is another tool for Six Sigma which shows you visual charts that represent distributions and can also show you deviations, especially within specified time intervals. This is useful in Six Sigma for identifying problems and defects, how often they occur, and how much they might be costing your operation in terms of time or money. Pareto chartsĪ Pareto chart is a chart that is a combination of a bar graph as well as a line graph chart, showing the relationship between individual values and a cumulative total. Flow charts can clearly show you the steps involved in a process, the inputs, outputs, events, and the individual and connected operations. Flow chartsįlow charts are good visualization tools to show you work current processes and are therefore useful in Six Sigma. To analyze cause and effect, you need to identify the problem, make clear the factors and context, identify possible causes, and propose solutions. When something goes wrong, that is the effect of a cause, and therefore cause and effect analysis is central to Six Sigma problem solving. In general, there are about 6 statistical management tools that project teams use for process mapping and quality improvement. Although today, the exact number of 6 is less important than the overall methodology. Six Sigma projects aim to limit the deviations as much as possible to a sigma of 6, which is why Six Sigma is so important for quality management. The Six Sigma abstractly refers to the standard deviation of 6, that is, 3 above and 3 below.

This refers to a standard or desired result from a process, and it describes how far from this one result, or range of results, one can expect, that is, how much one can deviate from this result.įor example, if you are manufacturing blueberry muffins with a standard muffin containing 8 blueberries, and you have a standard deviation of 2, that means on average your muffins will have the standard number of blueberries plus or minus 1 blueberry, meaning most muffins will have between 7 and 9 blueberries. To get into the details of Six Sigma, you need to know about standard deviations, otherwise associated with statistical bell curves. This also differentiates it from Critical Path Method, which deals with the envisioning and planning out of project scope writ large. It is particularly favored by larger businesses and in the construction sector, where it’s important to manage the costs of material infrastructure.Īnd whereas project management body of knowledge (PMBOK) method aims at ensuring project success on a general scale, Six Sigma focuses on streamlining specific aspects of the project. Customer satisfaction is one of the highest goals of Six Sigma.Ī glance at our project management methodologies comparison will show Six Sigma ranks among the top. In other words, Six Sigma is a methodology which uses statistics and data in order to achieve continuous business process improvement. One can say that the Six Sigma definition centers on producing deliverables with as few mistakes or variations as possible. The Six Sigma methodology focuses on improving business processes by eliminating wasteful or unnecessary steps. What is Six Sigma methodology? Our definition
