What does a fully built A/B test entail?

A fully built A/B test refers to a scenario where the product or idea being tested is completely developed and implemented for comparison. This means that two versions—Version A and Version B—of the product or feature are created with the intent to measure how each performs against a specific goal, such as conversion rates, user engagement, or customer feedback.

In this context, the term "fully built" indicates that both versions are fully functional and have all necessary elements in place, allowing for an accurate assessment of their performance when exposed to real users. This approach enables businesses to gather meaningful data on how each version meets user needs and engages customers, facilitating informed decision-making about which direction to pursue further.

Other options, while relevant to aspects of testing or product development, do not capture the essence of what a fully built A/B test encompasses. For example, a test measuring customer satisfaction focuses more on user feedback rather than comparing specific product variations. Evaluating two different ideas may indicate an aspect of testing but does not imply that these ideas are fully realized and operational. Lastly, a preliminary version of a product is not yet complete, which does not align with the definition of a fully built A/B test.
