Types of project scheduling
Project planning is the process of organizing a timeline for all project activities. This involves examining the interdependence of all activities, and coordinate all tasks to ensure a transition smooth from the beginning until the end of the project. There are several programming methods, which can meet the requirements of the type of project to be carried out, showing different representations of the timelines.
Critical path method
The critical path method is a pictorial representation of the project that is used to identify the general level while demand it. It also shows what activities are needed to complete the project and which are not as critical. In this technique, the project is plotted as a network, where the nodes represent activities and duration of each activity is represented by lines or arcs between the nodes.
The duration of each activity is estimated based on knowledge of the industry. Before building the diagram, identify activities, as well as the sequence of events. For example, activities A and B may occur simultaneously before activity C, producing a diagram of the form “>” where at the top left would place the activity A in the lower left corner to the activity B, and on the far right to the activity C.
Technical evaluation and program review
Technical evaluation and review of the program (PERT: Program Evaluation and Review Technique) is usually applied to more complex projects. a network diagram is also used. Activities and their duration is plotted as a network in the same way as in the method of the critical path. Unlike the above method, PERT allows greater flexibility in the time required to perform an activity.
As in the above method, the activities and the duration are defined; however, the latter is determined with the following formula: expected time = (time optimistic + 4 * (probable time) + pessimistic time) / 6. The Optimist is the shortest time period that can be carried out an activity, and the pessimist is the longest.
The Gantt charts are graphical representations of the phases and activities of a project, usually applied to plans in areas where there is very little variation between projects. These charts illustrate the start and end dates of each activity with a bar horizontal, below a horizontal line representing the date. Information on the complexity or size of an activity is not present, so the size of the bars does not imply greater or lesser duration or importance of the activities, which may cause a problem if the activities are carried out outside finished.
