What the Taguchi Method is: A partial factorial test developed by Genichi Taguchi. Originally created to provide quality control assessments, the method is now used by Adobe Target for its multivariate tests.
What the Taguchi Method is not: The Kaizen Method, which refers to the perpetual improvement of functions and processes. Building testing into regular routines and adapting it to KPIs is one example of the Kaizen Method in practice.
Why the Taguchi Method matters: In theory, the Taguchi method allows you to test more quickly than with a full factorial test. The Taguchi method, however, has attracted skepticism from some testing experts. Because of this, it may be necessary to verify winning variations with a more constrained experiment.
