The Gantt chart view is the most commonly used view in project management and tracking project schedules. Gantt chart view provides an illustrated version of task list, with Gantt bars that show the duration of your project's tasks across a timeline, relationship between tasks and the schedule.
A Network diagram is a graphical view of tasks, dependencies, and critical path of project. A box (also called a node) represents each task, and a line connecting two boxes represents the dependency between two tasks.
Critical path is a series of tasks that dictates the calculated finish date of the project. And baseline is a static copy of plan data that’s compared with actual and current data. Baselines helps to compare actual vs. planned.
