What is the difference between a Gantt chart and a PERT chart quizlet?

What is the difference between a Gantt chart and a PERT chart?

Essentially, a Gantt chart is a bar chart that lays out project tasks and timelines linearly. … A PERT chart, on the other hand, is structured as a flow chart or network diagram that displays all the project tasks in separate boxes and connects them with arrows to clearly show task dependencies.

What a PERT chart does quizlet?

A graphic display of schedule-related information. In the typical bar chart, schedule activities or work breakdown structure components are listed down the left side of the chart, dates are shown across the top, and activity durations are shown as date-placed horizontal bars.

What is the main difference between PERT and CPM quizlet?

What is the basic difference between PERT and CPM? The basic difference between PERT and CPM is that PERT requires three time estimates of activity completion time, whereas CPM uses only a single estimate.

What do Gantt charts and PERT charts have in common quizlet?

Gantt charts depict task dependencies, start times and stop times for project tasks, and provide a visual frame of reference for everyone on the project team. … The PERT chart, also sometimes known as a network diagram, depicts more complex projects and the relationships between activities.

What is PERT and CPM?

PERT is a project management technique, whereby planning, scheduling, organising, coordinating and controlling uncertain activities are done. CPM is a statistical technique of project management in which planning, scheduling, organising, coordination and control of well-defined activities take place.

What are the major differences between PERT and CPM?


PERT – Project Evaluation and Review Technique CPM – Critical Path Method
PERT – The main focus of PERT is to minimise the time required for completion of the project CPM – The main focus of CPM is on a trade-off between cost and time, with a major emphasis on cost-cutting.
Orientation type

How are PERT models differ principally from CPM models?

The difference between PERT and CPM is that PERT stands for Program Evaluation and Review Technique, and CPM stands for Critical Path Method. PERT manages unpredictable activities, whereas CPM manages predictable activities. PERT is related to the events, but CPM is related to the activities.

Is PERT more accurate than CPM?

PERT technique is best suited for a high precision time estimate, whereas CPM is appropriate for a reasonable time estimate. PERT deals with unpredictable activities, but CPM deals with predictable activities. PERT is used where the nature of the job is non-repetitive.
