How to Use This Calculator
  1. Enter Category 1 Count, Category 2 Count, and Category 3 Count.
  2. Set Category 4 Count, Category 5 Count, and Category 6 Count.
  3. Review Top Category, Top Category %, and Vital Few (80% cutoff).
  4. Use Trivial Many and Vital Few Cumulative % to inform your decision.
  5. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means

Category 1 Count
Number of defects or occurrences for the first defect category.
Category 2 Count
Number of defects or occurrences for the second category.
Category 3 Count
Number of defects or occurrences for the third category.
Category 4 Count
Number of defects or occurrences for the fourth category.
Category 5 Count
Number of defects or occurrences for the fifth category.
Category 6 Count
Number of defects or occurrences for the sixth category.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Category 1 Count = 45, Category 2 Count = 30, Category 3 Count = 12, Category 4 Count = 8 = 6 input(s) provided
  2. Calculate Top Category
    Category 1 = Category 1
  3. Calculate Top Category %
    Top Category %
    45 = 45
  4. Calculate Vital Few
    Vital Few
    3 = 3
  5. Calculate Trivial Many
    Trivial Many
    3 = 3
  6. Calculate Vital Few Cumulative %
    87 = 87
