incentive fee of R150,000 for finishing his project early. The two project managers agree that, should the reallocation be made, the value of incentive fee would be booked as a cost against the cable-stayed bridge project and transferred to the other project. The duration of Activity F can also be reduced. A step that would reduce duration to 3 weeks would increase the cost to R730,000 while a further step to reduce duration to 2 weeks would bring the total cost of this activity to R820,000. An increase of expenditures on Activity Q to a total of R2,929,000 would reduce the duration of this activity to 2 weeks.
