IV.4: In-Use Tickets Under the Three Payment Systems - Consists of two stacked bar charts, one for each phase, that compare the percentage of in-use Tickets assigned under each of the three payment systems from February 2002 through August 2003. In Phase 1 states in February 2002, about 70 percent of the Tickets were assigned under the traditional payment system, 5 percent were assigned under the outcome-only system, and 25 percent were assigned under the milestone-outcome system. The percentage of Ticket assigned under the traditional payment system jumped to 82 in March, fell slowly to 77 percent in June 2002, and then climbed steadily to 87 percent in August 2003. The share of Tickets assigned under the outcome-only payment system dropped from 5 percent to 3 percent in August 2002 where it remained unchanged. Under the milestone-outcome payment system, 26 percent of Tickets were assigned in February 2002, dropping to 14 percent in March, recovering slightly to 20 percent by May and then falling steadily to 11 percent by June 2003 where it remained through August of that year. When the rollout began in November 2002 in the Phase 2 states, 72 percent of the Tickets were assigned in under the traditional payment system, 2 percent were assigned under the outcome-only system, and 26 percent were assigned under the milestone-outcome system. The percentage of Ticket assigned under the traditional payment system dropped immediately from its 72 percent starting point in November to 65 percent in December, where it hovered through February until it began to climb continuously to 75 percent in August 2003, just over the original 72 percent at the outset in the previous November. The initial 2 percent of Tickets assigned under the outcome-only payment system in November 2002 rose to 8 percent in December, held steady through January 2003, and settled at 6 percent for the rest of the rollout period. The initial 26 percent of Tickets assigned in November 2002 under the milestone-outcome payment system rose to 30 percent in February 2003 and then fell steadily to its August 2003 level of 20 percent. |
