Question: Which Of The Following Is Basic Assumption Of PERT?

What is the primary purpose of a project network?

A project network is a graph (weighted directed graph) depicting the sequence in which a project’s terminal elements are to be completed by showing terminal elements and their dependencies.

It is always drawn from left to right to reflect project chronology..

What is critical path diagram?

In project management, a critical path is the sequence of project network activities which add up to the longest overall duration, regardless if that longest duration has float or not. This determines the shortest time possible to complete the project. There can be ‘total float’ (unused time) within the critical path.

Which of the following is a basic assumption of PERT quizlet?

Which of the following is a basic assumption of PERT? -Only critical path activities in the network must be performed. -There is only one complete route from the start of a project to the end of a project. -No activity in the network must be repeated.

What is a pert CPM chart?

A PERT chart is a project management tool that provides a graphical representation of a project’s timeline. The Program Evaluation Review Technique (PERT) breaks down the individual tasks of a project for analysis.

Which relationship model is most commonly used in the precedence diagrams?

Which relationship model is most commonly used in the Precedence diagrams? CORRECT: c. finish-to-start is the most commonly used relationship. AOA activity diagrams are only represented using which representation?

What are the limitations of PERT?

Limitations of PERT:In PERT, it is assumed that all the activities involved in the project are known in advance. … The assumption that a project can be sub-divided into a set of predictable and independent, activities may not hold true always. … PERT emphasizes only on time and not the costs.More items…

Which of the following is a basic assumption of PERT Mcq?

Which of the following is a basic assumption of PERT? There is only one complete route from the start of a project to the end of a project. Activity completion times are known with certainty. No activity in the network must be repeated.

What is the critical path in a project plan?

The critical path consists of the longest sequence of activities from project start to finish that must be completed to ensure the project is finished by a certain time. The activities on the critical path must be very closely managed.

What are the limitations of PERT and CPM?

Another of the limitations of PERT and CPM is that the larger the project, the more complicated the diagram. Above a certain level of complexity, all the lines you map out start to look incomprehensible rather than enlightening.

What are the steps in Pert?

PERT planning involves the following steps:Identify the specific activities and milestones. The activities are the tasks required to complete a project. … Determine the proper sequence of the activities. … Construct a network diagram. … Estimate the time required for each activity. … Determine the critical path.

What is the objective of crashing a project?

Crashing is done by increasing the resources to the project, which helps make tasks take less time than what they were planned for. Of course, this also adds to the cost of the overall project. Therefore, the primary objective of project crashing is to shorten the project while also keeping costs at a minimum.

Why is the critical path important?

Critical path allows teams to identify the most important tasks in a project. … This provides a higher level of insight into your project’s timeline and a correlation between tasks, giving you more understanding about which task durations you can modify, and which must stay the same.

What is critical path example?

For example, in the diagram below, activities E, F, G, H, and I make up the critical path. Their total duration is 100 hours. Activities B, C, D and E make up the second longest sequence with a total duration of 90 hours. … However, since activities E is common and in the critical path, it would have zero float.

Which of the following is not the limitation of pert?

Which of the following is NOT a limitation of PERT? Only one time estimate can be used for each activity. Slack is the amount of time an activity can be delayed without delaying the entire project. PERT, but not CPM, has the ability to consider the precedence relationships in a project.

Which of the following is a direct responsibility of the project manager?

Which of the following is a direct responsibility of the project manager? making sure that the people assigned to the project receieve the motivation, direction, and information needed to do their job.

What is difference between PERT and CPM?

PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. … CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.

What is a PERT analysis?

Program Evaluation and Review Technique (PERT) is a method used to examine the tasked that are in a schedule and determine a variation of the Critical Path Method (CPM). It analyzes the time required to complete each task and its associated dependencies to determine the minimum time to complete a project.

What are the features of PERT?

A distinguishing feature of PERT is its ability to deal with uncertainty in activity completion times. For each activity, the model usually includes three time estimates: Optimistic time – generally the shortest time in which the activity can be completed.
