A memo that presents findings or conclusions first and then provides supporting data describes?

A memo that presents findings or conclusions first and then provides supporting data is described as a "top-down" or "inverted pyramid" structure. This approach prioritizes clarity by immediately conveying the main message, allowing readers to grasp key points quickly. Supporting details and data follow to reinforce the conclusions and provide context. This format is particularly effective for busy audiences who need to understand the implications before delving into the specifics.
