A team segments its users by company size and industry because that data already exists in the CRM. What is the weakness of this approach?

• AThere is no weakness, since firmographic data is objective.
• BConvenient labels are not the same as predictive ones. Segments are useful when they group people by something that changes their behaviour, such as the problem they are trying to solve or the context they work in.
• CCompany size is too coarse, so revenue band should be used instead.
• DSegmentation should always be done by geography.
