Overviews
Overviews (also called introductions, headers, preambles, or advance organizers) set expectations about how information will be structured. They set up mental “compartments” in which the user can receive the incoming information, thereby reducing cognitive load.
Introduce a list of information by giving a short overview
Do.
Set user expectations about the information they’re getting. Here, the search window was 2 weeks, and 2 orders were found.
Don’t.
Don’t surprise the user with multiple results off the bat. Don’t use a vague introduction (“Here’s what I found”) when a specific one would provide more value to the user (e.g., the length of the list, search criteria).
