Which of the following is NOT a rational reason to reduce project duration? High overhead costs Incentive contracts Imposed deadlines Unforeseen delays High network sensitivity

High network sensitivity

An activity's normal time and cost are 8 and $100, respectively. Its estimated crash time and cost are 6 and $160, respectively. What is this activity's crash cost per time unit? $30 $33 $60 $153 $65

$30

When reducing project duration, the duration for a project that is optimal is at the point where Direct costs are the lowest. Direct costs equal indirect costs. Total project costs are the lowest. Indirect costs are the lowest. The project changes from time-constrained to resource-constrained.

. Total project costs are the lowest.

Which of the following is NOT a technique for accelerating project completion when resources are not constrained? Reduce project scope Do it twice—first fast and then correctly Establish a core team Assign additional staff and equipment Compromise quality

Compromise quality

The direct cost for completing an activity in the shortest time it can realistically be completed in is called its __________ cost. Expedited Reserve Normal Accelerated Crash

Crash

Which of the following projects would be least benefited if additional resources were added? Building a cabin Harvesting a crop by hand Moving to a new house Splitting and stacking a cord of wood Developing new software

Developing new software

In a Project Cost-Duration Graph, total project costs are a sum of Direct costs plus interest. Direct costs and the project manager's salary. Direct and indirect costs. Labor, material and equipment costs. Direct labor costs and the project manager's salary.

Direct and indirect costs.

Which of the following is NOT considered a project indirect cost? Consultants Equipment Interest The project manager's salary Supervision

Equipment

Without any formal planning, the president of a software company remarks in a speech that new technologically advanced software will be available in one year. This may lead to a project that must be done faster than anticipated. This is an example of reducing project duration caused by Time to market. High overhead. Imposed project deadlines. Incentive contracts. Unforeseen project delays.

Imposed project deadlines.

According to Brooks' Law, adding more people to a late project is most likely to have which of the following impacts? Decrease team motivation Get the project back on schedule Lead to burnout Make the project slip further Keep the project from slipping any further

Make the project slip further

Before crashing, direct costs for an activity represent normal costs, which typically mean low-cost, efficient methods for completing the activity in a(n) ________ amount of time. Expected Targeted Optimized Budgeted Normal

Normal

When the project team is salaried, which of the following is the preferred choice for accelerating project completion? Outsource project work Schedule overtime Assigning additional staff and equipment Establish a core project team Subcontract work

Schedule overtime

Which of the following correctly calculates an activity's cost slope? (normal cost - crash cost)/(normal time - crash time) (normal time - crash time)/(normal cost - crash cost) (crash cost - normal cost)/(normal time - crash time) (normal time - crash time)/(crash cost - normal cost) (crash cost - normal cost)/(crash time - normal time)

crash cost-normal cost)/(normal time-crash time

When reducing project duration, there will always be an optimum cost-time point where the total cost of the project is less than it was when the project was initially planned under normal conditions. True False

false

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? When during the project the activity will occur The inherent risk associated with the activity Resource availability after crashing that activity The level of difficulty involved in completing the activity How crashing will impact the morale and motivation of the individuals working on that activity

the level of difficult involved in completing the activity

Crashing can negatively impact the morale and motivation of the project team. True False

true

Crashing frequently results in overallocation of resources. True False

true

Direct costs are so named because they can be assigned directly to a work package and activity. True False

true

If indirect costs are a significant percentage of total project costs, reductions in project time can represent very real savings. True False

true

Indirect costs generally represent overhead costs such as supervision, administration, consultants, and interest. True False

true

One of the advantages of using a Project Cost-Duration Graph is that it keeps the importance of indirect costs in the forefront of decision making. True False

true

Shortening an activity's duration is termed crashing. True False

true

There are more options available for reducing project time if you are not resource constrained. True False

true

Total cost for specific project durations is computed and then compared with the benefits of reducing project time, before the project begins or while it is in progress. True False

true

When adding resources, there are limits as to how much speed can be gained. True False

true
