An activity's normal time and cost are 10 and $120, respectively. Its estimated crash time and cost are 7 and $180, respectively. What is this activity's crash cost per time unit?
$60 / 3 = 20
Which of the following projects would be least benefited if additional resources were added?
Developing new software
Compressing activities on a project with a sensitive project network will:
Increase risk of delaying the project and reduce scheduling flexibility.
Which of the following is NOT one of the more commonly used options for cutting project costs? Reduce project scope Have owner take more responsibility Move the completion date further out Brainstorm cost savings options Outsource project activities
Move the completion date further out
When determining which activity to crash, there are other factors that should be assessed beyond cost. Which of the following is NOT one of these factors? The inherent risk associated with the activity How crashing will impact the morale and motivation of the individuals working on that activity Resource availability after crashing that activity The level of difficulty involved in completing the activity When during the project the activity will occur
The level of difficulty involved in completing the activity
Erin has just learned that she needs to reduce the duration of her project to meet an imposed deadline. She has calculated the crash cost per unit and knows the maximum units each activity can be reduced. What is the next step?
identify the critical path
As a project is crashed and project duration is reduced, direct costs typically
increase
The less steep the cost slope of an activity, the
less it costs to shorten one time period
When a project manager must reduce project duration but resources are constrained, creating a software program that will have less functionality than originally planned or building a house without the bonus room and the basement that the owner originally specified in the plans would both be examples of
reduce project scope
Reducing project duration involves crashing all activities to their crash point. can only be done when resources are not constrained. is always more expensive. tends to increase network sensitivity. should be considered for all projects.
tends to increase network sensitivity
When reducing project duration, the duration for a project that is optimal is at the point where
total project costs are the lowest
When it is necessary to reduce project duration and resources are constrained, which of the following is NOT a reasonable option? Establish a core project team Fast-tracking Reduce project scope Compromise quality Use critical-chain project management
Establish a core project team
When crashing a schedule, this may set in when a least-cost method is used.
Fatigue and resentment
When reducing project duration, the crash cost per unit has to be calculated and the maximum units each activity can be reduced must be known. After this, the critical path must be identified. What is the next step?
Find the activity with the lowest crash cost
When the project team is salaried, which of the following is the preferred choice for accelerating project completion?
Schedule overtime
