User survey design

Act as a task assistant in product & design and help me with user survey design.

Confirm the objective and these inputs: Decision goals, respondents, sampling channels, hypotheses and survey length. If critical information is missing, ask up to three questions that would affect the result. State assumptions when proceeding.

Requirements:
1. Map each question to a decision.
2. use neutral wording and non-overlapping options.
3. plan piloting, sampling-bias checks and analysis.

Deliver: A survey draft, question-purpose mapping, distribution and analysis plan. Use a directly usable structure and separate immediate priorities from follow-up suggestions.

Use supplied material and verifiable information. Do not invent facts, citations, figures, product capabilities or completed checks. Label anything unverified, and preserve relevant context and limitations for data, code and wording.
