You work as a project manager for ABC Inc. You are currently overseeing a project on a high-rise building site. Your prime concern is to ensure that cranes are used effectively for moving materials. You also have to ensure that delivery trucks do not have to wait in a queue and that workers on the upper floors are able to get their deliveries on time. Which type of scheduling would be required in such a scenario?
Correct Answer:
C
Resource-oriented scheduling focuses on using and scheduling particular resources in an effective manner. This type of scheduling should be used whenever there are limited resources available for a project and the struggle for these resources between the project activities is intense. As a result, delays are likely to arise in such cases, as actions must wait until general resources become available. Resource-oriented scheduling is also suitable in cases where unique resources are to be used, such as when there is only one excavator available in an excavation operation.
Answer option B is incorrect. Time-oriented scheduling is a time-scheduling method that focuses on determining the finishing time of a project. It also specifies the crucial precedence relationships among the activities involved in the project. In time-oriented scheduling, the appropriate time is allocated for the whole project through the successive stages of the project life cycle.
Answer option A is incorrect. Critical path scheduling is a technique that calculates the minimum completion time for a project along with the possible start and finish times for the project activities.
Answer option D is incorrect. Network scheduling provides a basis for obtaining facts for decision making.
All of the following statements about the critical path are false except for which one?
Correct Answer:
D
The only statement that is true is that the critical path shows the project's earliest date for completion. A critical path is the sequence of project activities, which add up to the longest overall duration. This determines the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date
(i.e. there is no float on the critical path). A project can have several, parallel, near critical paths. An additional parallel path through the network with the total durations shorter than
the critical path is called a sub-critical or non-critical path. These results allow managers to prioritize activities for the effective management of project completion, and to shorten the planned critical path of a project by pruning critical path activities, by "fast tracking" (i.e., performing more activities in parallel), and/or by "crashing the critical path" (i.e., shortening the durations of critical path activities by adding resources).
Answer option C is incorrect. There can be more than one critical path, as two paths in the project network diagram can both take the same amount of time and be longer than any other paths in the project.
Answer option A is incorrect. The critical path can be, and often is, crashed with extra resources in an attempt to recover the project schedule.
Answer option B is incorrect. The critical path is the longest path to project completion.
Harry works as a project manager for BlueWell Inc. He is determining the budget of the project. According to the PMBOK, there are seven inputs to this process. Which one of the following is NOT an input to the determine budget process?
Correct Answer:
B
Reserve analysis is not an input to the determine budget process. It is a technique used for determining the budget. The inputs to the determine budget process are as follows: Activity cost estimates Basis of estimates Scope baseline Project schedule Resource calendars
Contracts Organizational process assets
You are the project manager of the GHT Project. Ben, one of your project team members, does not understand the idea of a milestone. Which of the following best describes what a milestone is?
Correct Answer:
A
A milestone is simply a significant point or event in the project. It does not have to be assigned to a specific date, but is usually assigned to the completion of project phases. A milestone is the end of a stage that marks the completion of a work package or phase, typically marked by a high level event such as completion, endorsement or signing of a deliverable, document or a high level review meeting. In addition to signaling the completion of a key deliverable, a milestone may also signify an important decision or the derivation of a critical piece of information, which outlines or affects the future of a project. In this sense, a milestone not only signifies distance traveled (key stages in a project) but also indicates direction of travel since key decisions made at milestones may alter the route through the project plan. To create a milestone, enter 0 (zero) in the Duration field. The task will automatically be classified as a milestone.
Answer option C is incorrect. This is a project constraint.
Answer option B is incorrect. A project goal is an objective for time, cost, scope, and other metrics.
Answer option D is incorrect. All activities must be completed in order to complete the project work. Activities that are not completed are quality issues that prevent the project from completing the project scope.
Della works as a project manager for BlueWell Inc. She has asked her assistant Beth to provide activity duration estimate for an activity. Beth provides Della the following estimate chart:
What will be the activity duration according to the PERT three-point analysis?
Correct Answer:
C
A three-point estimate records the optimistic, most likely, and the pessimistic duration and then records an average for the predicted duration. Three-point estimate is a way to enhance the accuracy of activity duration estimates. This concept is originated with the Program Evaluation and Review Technique (PERT). PERT charts the following three estimates: Most likely (TM): The duration of activity based on realistic factors such as resources assigned, interruptions, etc. Optimistic (TO): The activity duration based on the best-case scenario Pessimistic (TP): The activity duration based on the worst-case scenario The expected (TE) activity duration is a weighted average of these three estimates: TE = (TO + 4TM + TP) / 6
Duration estimates based on the above equations (sometimes simple average of the three estimates is also used) provide more accuracy.
Here it is,
TE = ( 24 + 28*4 + 36) / 6
= 272/6
= 29 (approx)
Answer options B, D, and A are incorrect. These are not the valid answers for this question.
