Experiment without the wait: Speeding up the iteration cycle with Offline Replay Experimentation

摘要

Ideas fuel innovation. Innovation drives our product toward our mission of bringing everyone the inspiration to create a life they love. The speed of innovation is determined by how quickly we can get a signal or feedback on the promise of an idea so we can learn whether to pursue or pivot. Online experimentation is often used to evaluate product ideas, but it is costly and time-consuming. Could we predict experiment outcomes without even running an experiment? Could it be done in hours instead of weeks? Could we rapidly pick only the best ideas to run an online experiment? This post will describe how Pinterest uses offline replay experimentation to predict experiment results in advance.
