Form against survey
A form collects information so somebody can act on a single response: an order, an application, a booking. A survey collects answers so somebody can analyse many responses together. The words are used interchangeably, but the purpose decides everything else, including whether questions should be required and whether anonymity helps or hurts.
The same tool builds both, which is exactly why people design a survey like a form and wonder why the data is unusable.

| Form | Survey | |
|---|---|---|
| Read as | One response at a time | All responses together |
| Required fields | Most, since you need to act | Few, since a forced answer is a false one |
| Identity | Usually needed to fulfil the request | Often better anonymous |
| Open questions | Fine, somebody reads each one | Costly, one is usually the limit |
| Success looks like | A complete, actionable submission | Enough responses to see a pattern |
Required fields mean opposite things
On a form, requiring a field is reasonable: without an email you cannot send the booking confirmation. On a survey, requiring an answer manufactures data, because somebody who has no view will pick something to get past the screen. The rule of thumb is that a form may require anything it needs to act; a survey should require almost nothing, and should offer a way to say not applicable.
Open questions cost differently
On a form, a free text box is cheap: one person reads one answer alongside the rest of the submission. On a survey with two thousand responses, every open question is hours of reading or a coding exercise. One open question, placed last and optional, is usually the right number. Two halves the answer rate on the first.
Anonymity changes the answers
A form almost always needs to know who sent it. A survey often gets better answers when it does not, particularly about anything sensitive: a manager, a service, a workplace. What breaks trust is the middle ground, a survey that says anonymous while collecting an identifier. Say plainly what you collect and what you will do with it, and people answer accordingly.
Questions people ask
Can one thing be both?
Sometimes, and it is worth noticing when it happens. A registration form with three optional feedback questions at the end is a form with a small survey attached. Keep the survey part optional and at the end, so an unanswered opinion question never blocks the registration you actually needed.
How long should each be?
A form should be as long as the task requires and no longer, since every field is one more thing between somebody and what they came for. A survey should be as short as the analysis requires, which is usually much shorter than the list of things you are curious about.
Should a survey show a progress bar?
Yes, and it should be honest. A progress bar that jumps because of conditional logic is worse than none, since it teaches people the estimate is meaningless. If the length varies a lot by path, showing the number of questions remaining is more truthful than a percentage.
Do I need consent wording on a survey?
If you are collecting anything personal or sensitive, say what you are collecting, why, and how long you will keep it, before the first question rather than in a link at the bottom. This is both a legal question in many places and the thing that decides whether people answer honestly.
How many responses does a survey need?
Enough that a difference you care about is bigger than the noise, which depends on the size of the difference rather than on a fixed number. The practical trap is reading a shift of a few points on thirty responses as a trend. If the sample is small, report the counts rather than the percentages.
