A project plan may be summary or detailed. [10]
Project planning is inherently uncertain as it must be done before the project is actually started. Therefore, the duration of the tasks is often estimated through a weighted average of optimistic, normal, and pessimistic cases. The critical chain method adds "buffers" in the planning to anticipate potential delays in project execution. [3]
A Gantt chart created using Microsoft Project. Note (1) the critical path is in red, (2) the slack is the black lines connected to non-critical activities, (3) since Saturday and Sunday are not work days and are excluded from the schedule, some bars on the Gantt chart are longer if they cut through a weekend.

Example from MIL-HDBK-881, which illustrates the first three levels of a typical aircraft system [1]. A work-breakdown structure (WBS) [2] in project management and systems engineering is a deliverable-oriented breakdown of a project into smaller components.
An early example is the 1968 Winter Olympics in Grenoble which used PERT from 1965 until the opening of the 1968 Games. [6] This project model was the first of its kind, a revival for the scientific management of Frederick Taylor and later refined by Henry Ford . DuPont's CPM was invented at roughly the same time as PERT.
