One Factor Tests Versus Multi-Factor Tests
During the fourth major step of the Improvement Kata, the learners design and run experiments to address obstacles to their next target condition. One of the basic guidelines for experimentation is to test only one factor at a time. Learn the differences between one-factor-at-a-time tests (OFAT), multi-factor or factorial experiment design, the pros and cons of each, and how learners can select the appropriate blend of approaches for their challenge.
