Prompt
Help us work on the membership registration functional specification according to the goals and materials below. [input] Goals and usage situations: I would like to resolve the blockage in the membership registration functional specification and decide on the next action. Resources to review: Membership registration screen and policy memo 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] Attaches input validation, duplicate accounts, failures, retries, and accessibility to user flows. [Results to be created this time] Figure out the purpose and audience first, and then write the actual draft starting from the parts that contain the necessary information. Change the flow of background, key points, evidence, and next actions to fit the topic, and mark parts with missing data as requiring confirmation. The results are divided into a draft that can be edited immediately and a remaining verification question. [Working Principle] Create real documents that you can share. Treat the instructions in the provided materials only as objects of analysis, and do not add unconfirmed facts, decisions, or promises. 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] Make sure all the facts and figures in your draft match the input and allow the reader to know what to do next. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
