Schedule Management

A Gantt chart is a bar chart of a project schedule over time. See a clear example, the key elements, how to make and read one, and its benefits and limitations.

Project milestones explained: what they are, examples by phase, milestone vs. task vs. deliverable, the milestone chart, and how they are tested on the PMP.

The precedence diagramming method (PDM) builds a project network from four dependency types: finish-to-start, start-to-start, finish-to-finish, start-to-finish.

A project network diagram maps activities and their dependencies to reveal the critical path. What it is, activity-on-node vs arrow, and how to build one.

Project dependencies link activities so one constrains another. The four logical types and the four categories: mandatory, discretionary, internal, external.

The critical path method finds the longest path of tasks that sets your project duration. How to calculate it, a worked example, float, and the PMP exam.

Total float vs free float, explained: what each one protects, the two formulas, a clear worked example, and how both are tested on the PMP and CAPM exams.

The five core project estimation techniques — analogous, parametric, bottom-up, three-point, and expert judgment — how each works and when to use each.

A PERT chart maps a project's activities to plan a schedule under uncertainty. What it is, the three-point formula, how to build one, and PERT vs Gantt.
