Information needed ideally would be who's the Target Audience/the end user, including age range, disposable spend, sex and location. Where is it being used and why? What's the key benefits from the offer? Is there any supporting analysis? Has the copy provided been proofread and edited? Is it digital or print format? What's the spec and are there contact details for the production team?
A digital survey can be provided with all the necessary fields to help gather all the necessary information. When a brief is put forward without these key questions being answered it often leads to confusion, numerous time-sapping amends, a non-cohesive design with unpredictable results.
