I have a task that will last 7 business days, but only require a total of 10 hours of "effort" (billable hours). For whatever reason, I can't seem to change the duration without changing the effort. My situation is I have assigned people to the task (and with each person, they have their own hourly rate). Because of my dilemma, this tasks is coming out to be $10,000, where it should only cost $5,300.
