  • Kruskal-Wallis Test
    The Kruskal-Wallis test is a nonparametric test comparing the medians of independent random samples from two or more populations. It works when the Y variable is continuous, discrete-ordinal,(...) Read More

  • Lead Time
    Lead Time (sometimes also referred to as Order Lead Time) is the total elapsed time from order entry to customer delivery. It can be measured by imaginary riding the order from start to(...) Read More
  • Lean
    The Lean approach aims at creating customer value efficiently. Lean comprises a set of tools, principles, and approaches which are designed to support this objective. Specify the value in(...) Read More
  • Lean Six Sigma
    Lean Six Sigma is the powerful combination of Lean and Six Sigma: Lean can be used to eliminate non-value-added steps while Six Sigma can be used to make processes more capable. Four good(...) Read More
  • Linear Shape
    Like the U-Shape, the Linear Shape is a type of Production Cell Layout. It has the following characteristics: Shape: The main characteristic of this is that there are a separate start and(...) Read More

  • Measure Phase
    This second phase of the DMAIC Project is all about measuring the extent of the problem. The Measure phase is where the data get collected which is the basis for good analysis.(...) Read More
  • Measurement error
    Measurement errors for continuous data comprise calibration issues and Gage R&R issues which can be detected when performing a measurement system analysis. Calibration issue: Total(...) Read More
  • Measurement System Drilldown
    Even if Gage R&R studies cannot be applied in their purest form, you must be confident that your data represents the process adequately. This can be done by using a Measurement System(...) Read More
  • Median
    The median is a measure of central tendency. It divides a distribution into two equal halves and can be thought of as the "middle" value of a data set. Calculation: Step 1: Arrange your(...) Read More
  • Mode
    The mode is a measure of central tendency. It represents the value with the highest number of occurences. Read also: Mean, median Learn more about this topic in our Basic Statistics(...) Read More
  • Morphological Chart
    The morphological chart is based on an analysis approach: the problem is divided into smaller units. For each subproblem potential subsolutions are developed, which are combined to create an(...) Read More
  • Motion (Type of Waste)
    The waste of motion refers to all movement of people and equipment which is not required to add value. Excess motion of people costs time and causes stress. In some cases, non-ergonomic motion(...) Read More
