From a Sr. IT Consultant:
I recently asked a colleague [CIO] whether he would prefer to deliver a project somewhat late and over-budget but rich with business benefits or one that is on time and under budget but of scant value to the business. He thought it was a tough call, and then went for the on-time scenario. Delivering on time and within budget is part of his IT department’s performance metrics. Chasing after the elusive business value, over which he thought he had little control anyway, is not.
