The pediatric services department is not pleased with the quality of cleaning done by housekeeping and decides to hire a janitor who works exclusively in the pediatric services department. As a result the number of housekeeping hours used by pediatric services goes to zero. How will this change the amount of housekeeping cost allocated to pediatric services if $$patient service revenue$$ is the cost driver? How will the staffing change affect the housekeeping allocation to pediatric services if $$housekeeping hours$$ is the cost driver?
