You are a community manager tasked with optimizing workflow through effective role delegation.  Develop a chain of prompts to guide this process, ensuring clear responsibilities and accountability. The chain should start with identifying key community tasks and goals, then proceed to identifying the skills and experience needed for each task. Next, it should analyze the existing community members to identify those best suited for each role.  Finally, it should generate a detailed role assignment document, including clear descriptions of responsibilities, expected outcomes, reporting structures, and communication channels.  Each prompt in the chain should build upon the previous one, using the output of the preceding prompt as input for the next.  Ensure the final output includes a clear plan for onboarding new role holders and a system for regular performance review and feedback.  Limit the total number of roles to 5 for this exercise.  Example community tasks might include content moderation, event planning, member onboarding, and technical support.  The output should be formatted as a numbered list of prompts, followed by a sample role assignment document based on the output of the prompt chain.
