two clustered bar charts 4_5

 

IV.5: In-Use Payments Under the Two New Payment Systems - Consists of two clustered bar charts, one for each phase, that compare the number of in-use Tickets assigned under the outcome-only with the number assigned under the milestone-outcome payment systems. The assignment rates in Phase 2, for both the milestone-outcome and outcome-only payment systems, are similar to the assignment rates in the early months of Phase 1. In both the Phase 1 and Phase 2 states, the number of Tickets assigned under the outcome-only system rose steadily, albeit slightly, from the beginning to the end of their respective rollout periods. The rise was more gradual in Phase 1, starting at about 7 Tickets in February 2002 and ending at 498 Tickets by August 2003. In Phase 2, the number of Tickets assigned under the outcome-only system rose from 2 in November 2002 to 384 by August of that year. In contrast, the number of in-use Tickets assigned under the milestone-outcome system in both phases rose more markedly over the rollout period. In Phase 1, the sharpest rise—from 65 to 299 Tickets—occurred from April 2002 to September 2002. The number if Tickets assigned then increased more gradually to 419 in February 2003, increasing slightly to 498 Tickets by August of that year. In Phase 2, the number of Tickets assigned under the milestone-outcome system was far greater, starting at a low of 25 in November 2002 and rising steadily to 1,277 by August 2003.
