More data is not necessarily the information the requirement needs.
A client may know the companies, markets, locations, functions, people or attributes it wants to understand. But the requested field does not necessarily define the conclusion that the information must support.
An industry field may not establish what an organisation currently does. A job title may not establish responsibility. A website may not establish association with the intended entity. An available email address may not establish the communication route required.
The sourcing requirement should begin with what the information needs to support—not merely which fields need to be populated.
