Schedule-driven development programs are different from standard acquisition efforts. All programs have a measure of schedule pressure. Once baselined, the iron triangle of cost, schedule, and technical scope is at play. But truly schedule-driven development programs behave differently and have different needs. Attempting to plan, execute, and manage a truly schedule-driven development effort as if it were a standard acquisition program done faster will not work, will slip, will cost moreand will probably get you fired.
