Risks of Not Performing Step 3
It is impossible to build a BI application ad hoc without a plan. You may as well take a dart, throw it at a calendar, and commit to the date the dart hits. In other words, the project will veer out of control if it is not planned well. You may miss deadlines, have runaway expenses without accountability, implement the wrong solutionor you may never get to the implementation. A BI decision-support environment is very complicated, and BI projects are very costly. The risks of undertaking such projects without adequate planning and control are unacceptable.
