Gantt charts can be broken down into further levels of detail. For example, an item on a high-level Gantt chart might be testing. Another Gantt chart can be created that breaks testing into more detailed tasks related to testing. PERT charts PERT charts are another common project management tool. PERT charts are best utilized when the project is predictable and straightforward.
PERT charts provide a good illustration of project tasks and their interdependencies.
They graphically represent the sequence of tasks required to complete a project. The PERT chart directly establishes relationships and sequential dependencies among project tasks. The total time to complete a project can be determined by locating the longest path in the chart, the critical path. When the critical path is clearly identified, it is much easier to determine the repercussions of not completing tasks on a timely basis. When a task on the critical path is not completed, the overall project schedule will be impacted accordingly.
