Truly successful BI projects will look like IT project failures to many people.  For anyone used to delivering traditional IT systems (desktop productivity, back office and front office automation, data entry systems, etc.), BI has always seemed frustrating.  The model of defining requirements, delivering requirements, and then maintaining the system over a three to five year life span just doesn’t seem to work in BI.  Many BI practitioners, particularly first-time implementers, will report with a large degree of frustration, “Every time we give them what they asked for, they come back with changes in their requirements;  we never seem to get it right, they can’t tell us exactly what they need, and we can’t keep up.”
