Generate standard or custom orthogonal arrays from factor/level settings and create efficient combinational test cases.
Set the number of factors (parameters) and levels (2 or 3)
Select from L4/L8/L9/L16/L18/L27 or run custom generation
Assign factor/level names and download the result as CSV or Excel
Only arrays compatible with factor/level settings are selectable
Missing names are auto-filled as F1, F2...
Missing names are auto-filled as L1, L2...
Orthogonal arrays help you verify factor interactions while reducing test runs versus full combinations. This tool supports standard Taguchi arrays and custom orthogonal generation for practical QA test design.
They reduce the number of runs while preserving broad pairwise interaction coverage across factors.
Standard generation uses well-known Taguchi arrays. Custom generation builds an orthogonal array based on your factor and level counts.
L18 is a mixed-level array. The tool selects columns compatible with the chosen level count.
