Kinds of network plans

There are different kinds and variants of network plans. The following kinds are differentiated from network plans:

Here still GERT (Graphical evaluation is missing. and Review Technique)"…

In at present available critical path method programs the methods are mixed and very no longer relevant. As general application recommendation procedure arrow network plans, e.g. CPM, should be used if the project simple relationships, which must be changed rarely. CPM network plans are less suitable for costing and resource allocation. Procedure multipoint network plans, e.g. MPM, have the advantage that the procedure knots much different information can be assigned. A further advantage is that they can be changed relatively fast. Event multipoint network plans such as PERT should be used with projects, with which those procedures cannot be pre-defined either temporally or structurally exactly (stochastic Netzplanmethode).

Due to its relatively simple handling CPM and MPM are furthest common.

Advantages of the critical path method

The network plan is a very understandable, descriptive and meaningful representation, because the network plan supplies an excellent overview of the whole of the partial procedures of a project and their interdependences. By the illustration of the entire project by the network plan the necessity exists to think out and on a respective subproject not insist the entire project. The network plan is fast detectably and therefore also easily updatable actually and makes a relatively accurate forecast possible of important intermediate dates and the completion date. Further temporal bottlenecks (critical path) and floats are easily recognizable with the network plan, since by project management often commodity for example different colors for procedures of the critical path can be assigned.

Contrary to planning with bar charts can be differentiated with respect to the critical path method between expiration and scheduling. By the possibility of the representation of logical dependence between procedures a flow diagram can be developed independently of according to schedule acceptance. Can briefly summarized be said:

• Network plans form an understandable, descriptive and meaningful representation of the entire course of project.
• They are fast detectably and easily updatable (if the project data are processed electronically).
• Critical procedures and bottlenecks are easily recognizable.
• With its production it is necessary to think the entire project out.
• A majority of the available project management often commodity supports critical path method.

Disadvantages of the critical path method

• The diagram, the network plan, is used for larger projects, smaller projects can frequent be represented in a representation derived from it, the bar graph (Gantt diagram) partially somewhat more user-friendly. Alternative ones to the critical path method would be the Gantt evenly specified or the Plannet technology (an advancement of the Gantt technology).
• If the network plan is too in detail planned, this is to be equated with enormously high control expenditure, since up to 200 partial procedures must be at the same time UP ton DATE, since otherwise distortions in planning arise. If the network plan is too abstractly developed and incomprehensibly described work procedures, then the probability is high that this about the users is not understood. Network plan activities, which are subject to a very strong change process, are not controlable. That leads to frequently unrealistic plans and to it that the planner lags behind to the things.
