The correct answer is: A. Bar chart method.
A bar chart method is a graphical representation of a project schedule. It shows the start and finish dates of each task, as well as the dependencies between tasks. This information can be used to track the progress of a project and identify potential risks.
A milestone chart is a type of bar chart that shows the major milestones in a project. Milestones are significant events that mark the completion of a major phase of a project. They can be used to track the progress of a project and to measure the overall success of the project.
Critical path method (CPM) is a project management technique that is used to identify the critical path of a project. The critical path is the sequence of tasks that must be completed on time in order to complete the project on time. CPM can be used to schedule and monitor projects and to identify potential risks.
Programme Evaluation and Review Technique (PERT) is a project management technique that is used to estimate the time and cost of a project. PERT uses a probabilistic approach to estimating time and cost, which takes into account the uncertainty of the project. PERT can be used to schedule and monitor projects and to identify potential risks.
Bar chart method is the first method invented for planning projects. It is a simple and effective way to visualize the schedule of a project and to track its progress.
