Question

Compare the main strengths and weaknesses of the Gantt chart and PERT for project management, and give your opinion on which you believe is the most effective for project management.

Answer 1

Gantt Chart: It was invented by Henry Gantt. It is useful to monitor the project from start to finish. Gantt Chart displays each task over time so that task completion can be monitored.

STRENGTHS OF GNATT CHART	WEAKNESS OF OF GNATT CHART
Gantt chart helps to visualize the task	It is a complex diagram and difficult to understand
Gantt chart helps to prevent gaps in the communication	It should be periodically updated
Gantt chart helps to track the project activities.	It is time-consuming
It helps to organize the thoughts	Size of the bar does not indicate the amount of work
Resource allocation would be easy	It cannot be visible on a single sheet of paper
Complex project activities can be easily done.	The complex diagram makes us confused sometimes

PERT: PERT stands for program evaluation and review technique. It was discovered by the American navy department. It consists of a network diagram. The network diagram illustrates the minimum time required to complete the project, network connections between each activity, and the risk involved in the project.

STRENGTHS OF PERT	WEAKNESS OF PERT
It helps to identify the time required to complete the project in advance	It estimates only the time required not the cost
It helps identify the path of the project	Errors in time estimation may result in the delay of the project
It helps to identify the problem in the project and take appropriate actions	Frequent update required
It helps to increase the efficiency	expensive

Opinion:

Gantt chart is more useful for smaller projects and PERT is useful for complex projects. Gantt chart precisely estimates the time required completing each activity; it helps to communicate effectively, easy, and straightforward.The gnatt chart more reliable over PERT.
