A PERT chart helps a project manager analyze a project’s tasks and estimate the amount of time required to complete each task in the project . ... For example, if an arrow is drawn from Task No. 1 to Task No. 2 on a PERT chart, Task No.
What is PERT CPM example?
Meaning:- PERT is a methodology for project management . ... Meaning: CPM is a statistical project management technique which manages well established project activities. Suitable for: Non-research based projects for example Civil Engineering Construction, ship building etc. Estimates: One time estimate.
What is PERT explain?
Program Evaluation and Review Technique (PERT) is a method used to examine the tasks in a schedule and determine a Critical Path Method variation (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 PERT activities?
PERT activity – The performing of a task, recorded by the time taken to do so and the resources required. PERT sub-activity – The breaking-down of activities within an activity. Optimistic time – As the name suggests, the minimum time required to complete an activity.
What is PERT and where it is used?
Program Evaluation Review Technique (PERT) is a project management planning tool used to calculate the amount of time it will take to realistically finish a project . PERT charts are used to plan tasks within a project — making it easier to schedule and coordinate team members.
What are the major differences between PERT and CPM?
| Abbreviation | PERT – Project Evaluation and Review Technique CPM – Critical Path Method | Focus | 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 |

What is the difference between PERT & CPM?
1. 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 PERT diagram?
A PERT chart, sometimes called a PERT diagram, is a project management tool used to schedule, organize and coordinate tasks within a project . It provides a graphical representation of a project’s timeline that enables project managers to break down each individual task in the project for analysis.
What are the advantages of PERT?
- Planning For Large Projects in PERT – The scheduling of project activities is done easily with the help of the PERT system by the project manager. ...
- Visibility of Critical Path in PERT – The PERT method will show the critical path in a well-defined manner.
How is PERT calculated?
PERT is an estimating technique that uses a weighted average of three numbers (see below) to come up with a final estimate. The resulting PERT estimate is calculated as (O + 4M + P)/6 . This is called a “weighted average” since the most likely estimate is weighted four times as much as the other two values.
How do I create a PERT diagram?
- Step 1: List out your project milestones and tasks. ...
- Step 2: Identify the sequence of those tasks. ...
- Step 3: Determine the time criteria for your tasks. ...
- Step 4: Draw up your PERT diagram. ...
- Step 5: Draw out your critical path. ...
- Step 6: Update your PERT chart as needed.
How do you use the PERT method?
- List the activities and milestones. The first step is to determine the tasks required to complete the project.
- Determine the sequence of activities. ...
- Build a network diagram. ...
- Estimate the activity durations. ...
- Determine the critical path.
What is PERT chart and Gantt 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 are the advantages of PERT and CPM?
The techniques of PERT and CPM help greatly in completing the various jobs on schedule . They minimise production delays, interruptions and conflicts. These techniques are very helpful in coordinating various jobs of the total project and thereby expedite and achieve completion of project on time.
What are the similarities and differences between PERT and CPM?
| BASIS FOR COMPARISON PERT CPM | Focuses on Time Time-cost trade-off | Estimates Three-time estimates One time estimate | Appropriate for High precision time estimate Reasonable time estimate | Management of Unpredictable Activities Predictable activities |

Where is PERT and CPM used?
The use of project planning and control techniques based on PERT or CPM are now common in all types of civil engineering and construction work , as well as for large developmental projects such as the manufacture of aircraft, missiles, space vehicles, and large mainframe computer systems.
