Completely agree, requirements are key and often badly defined due to the customers’ lack of knowledge of the intricacies of the system. You are correct to ask for clarity or it could come back to bite you later on.
I’ve just had a spec through from a BA which consists entirely of screenshots of an existing system with no technical definitition of any of the requested fields so relate to this right now.
I have somewhat of a pet extension to projection theory… Many people who are anti-gay think that it is a choice as they themselves have made that choice. ie. They are repressed bisexual/gay.
Completely unsubstantiated with no evidence but I find it fun to think about as it would explain their complete misunderstanding of it not being a choice. “I made the tough choice and am living with it, why can’t they?!”
