plz tell me difference in gantt chart and perth chart in details thanks


GANTT CHART
Gantt chart is a project planning tool that can be used to represent the timing of tasks required to complete a project.
Since Gantt chart is simple to understand and easy to construct therefore, they are used by most project managers for all but the most complex projects.
Gantt charts have become a common technique for representing the phases and activities of a project work breakdown structure (WBS), so they can be understood by a wide audience.
In a Gantt chart,
  • each task takes up on row
  • Dates run along the top in increments of days, weeks or months, depending on the total length of the project.
  • The expected time for each task is represented by a horizontal bar whose left end marks the expected beginning of the task and whose right end marks the expected completion date.
  • Tasks may run sequentially, in parallel or overlapping.
  • As the project progresses, the chart is updated by filling in the bars to a length proportional to the fraction of work that has been accomplished on the task.
  • This way, one can get a quick reading of project progress by drawing a vertical line through the chart at the current date.
  • Completed tasks lie to the left of the line and are completely filled in.
  • Current tasks cross the line and are behind schedule if their filled-in section is to the left of the line and ahead of schedule if the filled-in section stops to the right of the line.
  • Future tasks lie completely to the right of the line.
Since a pictorial presentation is a better option to display a systematic work procedure, a plan of the system analyst can be seen on the following Gantt chart.
Each step on the rows from top to bottom in vertical y axis has been included. Date starts from most left column to right side on the top of the chart incrementing in days, weeks or months, depending on the total length of the Stock Control project for the Car-Showroom.
The expected time for each task is represented by a horizontal bar whose left end marks the expected beginning of the task and whose right end marks the expected completion date

PERT CHART
It is a project management tool that provides a graphical representation of a project timeline allowing the tasks in a particular project to be analyzed, with particular attention to the time required to complete each task, and the minimum time required to finish the entire project.
  • A PERT chart is a graph that represents all of the tasks necessary to a project’s completion, and the order in which they must be completed along with the corresponding time requirements.
  • Certain tasks are dependent on serial tasks, which must be completed in a certain sequence.
  • Tasks that are not dependent on the completion of other tasks are called parallel or concurrent tasks and can generally be worked on simultaneously.
  • PERT charts are preferable to Gantt charts because they more clearly identify task dependencies; however, the PERT chart is often more challenging to interpret. As such, project managers frequently employ both methodologies.
