2KVarianten
2KVarianten is a term used in German-speaking technical contexts to refer to a pair of alternative versions of a product, document, dataset, or interface that are intended to be evaluated against one another. The concept is commonly employed in testing, evaluation, and configurability, where two concrete variants are produced and compared in a controlled setting. In a typical 2KVarianten arrangement, two variants (often labeled A and B) are made available, and a mechanism—such as randomized assignment or deterministic routing—divides users, samples, or data points between them to ensure balanced comparison.
Applications include software feature testing (A/B style), UI/UX design exploration, marketing or product copy variants, localization
Implementation considerations include defining clear success metrics, ensuring proper randomization, avoiding cross-contamination between variants, and predefining
Related concepts are A/B testing, multivariate testing, and variant management. The term 2KVarianten is primarily used
