Question

compare and contrast flow charts and Gantt charts, and discuss the value of PERT networks

Answer 1

Flowcharts and Gantt charts are both effective tools to plan projects. However, when it comes to project execution, both have different uses and applications. For a complex plan with a longer duration, a Gantt chart is better, and for short term and smaller projects, a flow chart can do the trick on its own. In some cases, Gantt charts and flowcharts are used in combination. Both types of charts can be easily made using Creately’s online flow charting tools and Gantt tools.

As PERT (Program Evaluation and Review Technique) is one of the successful and proven methods among the many other techniques, such as, CPM, Function Point Counting, Top-Down Estimating, WAVE, etc. PERT was initially created by the US Navy in the late 1950s.

PERT Chart vs Gantt Chart Differences. PERT charts are generally used before a project begins to plan and determine the duration of each task. Gantt charts are used while a project is happening to break projects into smaller tasks and highlight scheduling constraints.
