Help us conduct subscription churn analysis according to the goals and materials below. [input] Goals and usage situations: I want to clear the block in my subscription churn analysis and decide my next course of action. Resources to review: Subscription start/cancellation records and reasons Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] Check the definition, period, customer group, and reason for churn, and do not overinterpret small samples. [Results to be created this time] In this material, create an empty form to separate the structure to be reused from the content that changes every time. Briefly describe the content and standards for writing in each space, and provide an example filled with current data. Don't include one-off proper nouns or fictitious achievements as fixed rules. [Working Principle] Distinguish between observed facts and business hypotheses to be tested. Do not fill in sales, demand, and costs arbitrarily, but leave actual basis and calculation conditions. Consider the resource constraints of your implementation. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] You can use the same form for other cases and make sure that required inputs are not omitted. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
