How to Run a Pilot Study Before You Launch
A pilot is a small, deliberate test run of a survey before it goes to your full audience - the cheapest insurance against launching something broken.
Recruit 10-20 people who resemble your real audience
Colleagues are fine for catching typos, but they won't tell you if a question confuses an actual customer. Pull a small, real sample if you can.
Check comprehension, not just completion
Ask pilot respondents to think aloud, or follow up afterward: "what did you think this question was asking?" A question that seems clear to you as the author can still land differently for someone with no context.
Time it honestly
Note how long the pilot actually took, not your estimate while writing it - authors always underestimate. Use the real number in your survey description.
Walk every logic path
Make sure your pilot group collectively hits every branch and skip rule, not just the default path - logic bugs hide in the paths nobody tests.
Run a mini version of your analysis
Export the pilot responses and try building the report you're planning for the real data. If a question's answers don't actually answer what you need, you'll find out now instead of after full launch.
Fix, then relaunch clean
Once you've made changes, start a fresh survey rather than reusing the pilot's link - mixing pilot and real responses in one dataset is hard to untangle later.
