“Add Analytics” is a Terrible Requirement

It's not really a requirement, any more than "Add a user interface" would be a requirement. It describes a perceived need (which could be real or marketing created) that ought to be broken down into specific requirements.

Most people/companies don't have any idea what can be done with their data or how it would help their business, and as such, aren't in the position to formulate clear requirements. Saying "I want to add analytics" is just shorthand for "I've got a lot of data, some of which I suspect could be valuable and want to start doing something with it."
