Good afternoon, everyone, my name is Zhang Jinbo, from the financial industry of Volcano Engine. I was the product manager of several product lines such as AB testing, intelligent release and performance monitoring. Volcano Engine is an enterprise-level technical service platform under ByteDance. Taking this opportunity, I am honored to share with you the methodology and related thinking of ByteDance AB test-driven sharing. Let me share a real case job title email list that happened to a car rental company. As plan planners, or leading decision-makers, we may encounter similar problems: there are multiple plans for the same goal, and the leaders of each plan often have different opinions. This is the case of the car rental company. The company hopes to increase the conversion rate of car rental this year. Therefore, the product manager and the operation manager have different opinions on the optimization process design of rent and deposit, and the boss needs to consider whose plan to use. . The operation manager believes that the rent and deposit should be placed on the same payment page, because the shorter the process, the better. Once the number of operation steps increases, the user's willingness to use will be reduced. The product manager believes that two payment pages are more reasonable, and the rent should be paid first, and then the deposit should be paid, because when the user pays thousands of dollars at once, the user's psychological pressure will suddenly increase.
