Start with the use of each item
For every survey question or tracking task, identify who will use the answer and how. “It might be interesting later” is a weak reason to collect sensitive information repeatedly.
Existing data may answer some questions, though their definitions and permissions still need review.
Burden is not only questionnaire length
Repeated logins, inaccessible formats, travel, unclear wording, and requests at inconvenient times can matter as much as the number of items. A short form can still be difficult to complete.
| Burden source | Possible design question |
|---|---|
| Repetition | Can an unchanged fact be confirmed rather than re-entered? |
| Sensitivity | Is the detail necessary at this level? |
| Accessibility | Can people use the format provided? |
| Timing | Can collection fit the service workflow? |
Less data can also create a cost
Removing a measure that identifies harms or unequal reach may weaken the evaluation. The aim is proportionate collection, not minimal collection regardless of consequences.
Explain why information is requested and what choices participants have. Pilot the process with intended users. A credible evaluation needs usable data, and data quality often improves when the collection respects the circumstances of the people providing it.
