-### Survey reminders: 
-- Be respectful of the survey-takers' time, in general try to keep the survey short in duration, with specific and targeted questions. You can always ask if you can follow up with them to get deeper context.
-- We want to measure improvements too, so using trendable questions helps us assess how we’re doing 
-- We encourage mix of general and targeted surveys
+### Survey design guidelines
+
+1. Aim for less than 15 questions that are short and concise
+2. Group questions into logical sections
+3. Use demographic questions (filtering, grouping)
+4. Start with easy, closed-ended questions
+5. Use up to one open-ended question
+6. Set questions to 'Required' only if necessary
+7. Use clear language without jargon and acronyms.
+8. Do not collect Personally Identifiable Information (PII)
+9. Avoid leading questions (written in a way that influences survey responses)
+10. Avoid loaded question (assumes something about the respondents that might not be true)
+11. Avoid double-barreled questions (asks people to give only one answer when asking about two things) 
+12. Avoid absolutes (always, every, etc.)
+13. Be careful with negation in a questions
+14. Ensure questions options are mutually exclusive (e.g. 1-9, 10-99)
+15. Include 'Other' option if relevant
