  • Pp
    The Pp-Index compares the tolerances of the process (how it should be) to the process spread (how it is): Pp = (USL - LSL) / 6sLT   Assumptions: - The long-term(...) - Read More
  • Ppk
    The Ppk-Index compares the distance from the process center to the nearest Specification Limit (how the process should be) to the process spread (how it is): Ppk = Min ( (USL -(...) - Read More
  • Practical Vision
    A vision is a compelling picture of a preferred future motivating us to act. The practical vision shows the process that would theoretically be practical, still extreme and may require(...) - Read More
  • Prevention Costs
    Costs of all activities that are designed to prevent poor quality in products or services from arising. E.g. costs of - quality planning - quality education - training, -(...) - Read More
  • Process Capability
    Process Capability compares how the process actually is (described by its mean and its standard deviation), compared to how it should be (described by its specification limits USL and(...) - Read More
  • Process Owner
    The process owner is responsible for - leading process teams in the development and use of process management systems - providing appropriate process reporting to leadership -(...) - Read More
  • Process Stability
    A key concept in Operational Excellence is the distinction between variation that is due to common vs. special causes. The process is stable, or "in control", when there is only common(...) - Read More
  • Production Leveling
    - Production Leveling (also called Production Smoothing) is aimed at reducing the variation in quantity in a production line - Leveling creates a constant production pattern that can(...) - Read More
  • q

  • Quality Function Deployment (QFD)
    Quality Function Deployment (QFD) is a method for structured product planning and development - helps to specify a product´s Critical to Quality (CTQ) characteristics based in the(...) - Read More
  • Quality Loss
    Quality losses are all products that are not First Pass Yield (FPY). Even if the product just needs "some" rework to make it fit, it is a Quality loss and should be counted as such. - Read More
  • r

  • Run Time/ Running Time
    Running Time = Net Operating Time - Downtime Losses Downtime Losses: Equipment Failure, Set-Up Time, downtime due to sick leave, quick stops for adjustments or cleaning - Read More
  • s

  • Scatter Plot
    A scatter plot can be used to visualize cause-effect relationships between a continuous X and a continuous Y.  - Read More
  • Set-Up-Time
    Setup time is a Lean Metrics describing the elapsed downtime for actions that must be taken before a product or service can be produced. Work with Set-Up Time to - Increase(...) - Read More
  • Sigma Level (Process Sigma)
    The Process Sigma or Sigma Level - is the concept of translating the yield  - Sigma Level refers to the number of Sigma, or process standard deviations, between the mean and the(...) - Read More
  • Six Sigma
    Six Sigma means - rigorous causal thinking to identify the unknown root causes of your business problems - using data and statistical tools to identify what drives the quality of (...) - Read More
  • Stratification
    Stratification is the process of subdividing a group of data based on a particular characteristic in order to provide better insight into the data pattern. Frequency plots can be(...) - Read More
  • Swimlane Chart
    A Swimlane Chart is a type of Process Map that is used to show the complexity of a process (e.g. decision loops). It puts the focus on displaying the handovers and functions involved in a(...) - Read More
  • t

  • Takt Time
    Takt time is calculated based on customer demand and indicates the amount of time production has to provide "one output" on average. Work with Takt Time to - Adjust your(...) - Read More
  • Target Output
    Target Output is the output you calculated when the machine runs at full speed. Read also: Actual Output - Read More
  • Throughput Time (TPT)
    Throughput Time (TPT) is a Lean Metric used to describe the elapsed time from process start to process end (of piece of material or information; “Ride the material”). The overall(...) - Read More
