"here are several surveys indicate that a significant percentage of data
warehouses fail to meet business ob/ectives or are outright failures. 0ne of the
reasons for this is that re1uirement analysis is typically overloo#ed in real

based on the "ropos methodology. "wo different perspectives are integrated for
re1uirement analysis4 organi5ational modeling! centered on sta#eholders! and
