What is a project network?

The project diagram, also known as a priority diagram, is a handmade or software diagram that shows relationships in time and dependence of the steps needed to complete the project. The diagram explains which steps can prevent others which steps must replace others and which may occur simultaneously as well as other project restrictions. It also shows when the delivery time allows you to start one task before completing the other, and when the delay time is needed after the step before starting a successful step. The scheme of the project network is useful in calculating initial and end data, distribution of resources and staff and analysis of planning options.

There are a number of ways to create a graphical representation of the project diagram. It is common to use the procedure left to the right to show the change from earlier times, left, later time, right. It is also common to prepare for the creation of a network diagram of the project by preparing activities, roughly in chronological order, with verbalEven notes about addictions.

One type of graphic representation is the method of priority diagram (PDM), also known as the method of activity on the node (AON). This method uses a rectangle to represent any activity and an arrow to represent relationships. If multiple predecessors or more successors or several lines of development are taking place, this is given in the diagram. PDM also shows completion to start addictions (FS) where one activity must complete before the other begins; Start to start dependence (SS), where one activity can only begin when another activity has started; Start completing addiction (SF) where one activity cannot be completed before starting further activity; and complete the addiction (FF) where one activity cannot be completed before the next activity is completed.

with a project network diagram is able to calculate the ES (early start), EF (Early Finish), LS (late start) and LF (late completion date) anda critical way. EC is the oldest time of the initial period for an incomplete project or part of the project, while EF is the first date when it can complete an incomplete project or part of the project. LS is the latest date when the project or the project can begin without causing a delay in an important milestone, usually the completion date, while the LF is the latest date when it can complete the project or the project without delaying an important milestone, either the beginning of the next step or completion date. The critical way is the sequence of activity by which the earliest date of completion of the project is determined.
