'Effective domain modelers are knowledge cruchers. They take a torrent of information and probe of the relevant trickle. They try one organizing idea after the other, searching for the simple view that makes sense of the mass. Many models are tried and rejected or transformed. Success comes in an emerging set of abstract concepts that make sense of all the detail. This distillation is a rigorous expression of the particular knowledge that has been found most relevant.'

(Eric Evans - 'Domain driven design - Tackling Complexity in the Heart of Software')
