Schedule is a time, cost and resource control and management tool, identify activities for entire project with time scales, required budget and resources, and relations with dependencies. Bar Chart Schedule is a simple schedule and shows a graphic presentation of work activities by a time scaled bar line.Gantt Chart is one of the schedule control and management tool, shows bar chart with activities and time scale. The Gantt Chart schedule was invented in 1917 by the US engineer, Henry Gantt.Program Evaluation Review Technique (PERT) is one of the schedule control and management tool for planning and evaluating progress of complex programs. It shows graphical relations among activities, and time scale of each activities, and required total duration of the project that is to determine the time required to complete each element in terms of pessimistic, optimistic, and best guess estimates. The PERT was developed by US Navy in the 1950s.Network Schedule (Scheduling) is a graphical display of logical order of activities and a method of scheduling work process where various related events are programmed into a sequential network on the basis of starting and finishing dates.
Most Common Scheduling Techniques in Project Management. Now that you know all the elements that belong in your project schedule, you can start to assess which of the different techniques for project management you will use. There are several ways to approach project scheduling based on your experience and the complexity of your project.

The Network Scheduling shows the project critical path (sequential activities have zero float). Often called as a CPM (Critical Path Method) Schedule.Critical Path Method (CPM) is a popular network schedule management and control tool that shows activity sequences (predecessor and successor) and relationships (finish to start, finish to finish, start to start, start to finish) of all activities. The longest path resulting from complete works or tasks is called the critical path. The CPM is a supporting tool for developing the shortest duration to complete the project and the best way considering all factors such as resource mobilisation to complete the project.
The CPM was developed in the late 1950s by Morgan R. Walker of DuPont and James E. Of Remington Rand. A commonly used tool for CPM scheduling is the Primavera software. Front End Schedule provides information of the project overall schedule that shows the starting and ending date, usually a bar chart schedule.
The Front End Schedule is used for the status reporting and permits documentation.Look Ahead Schedule (or Window Schedule) is shown present, previous and future time period on one window. There is 3 weeks for a weekly or 3 months for a monthly look ahead schedule.The Primavera is a network schedule control software, was launched in 1983 by Primavera Systems Inc.
