Network diagram

Changing the time frame of any of the tasks on the Gantt Chart shows up areas where this will cause conflict and hence where priorities must be modified to fit in with the target completion date. 

On the basis of events and activities and the order or sequence in which they will happen within the project the Project Manager can develop what is called a network diagram. The Project Manager also has to determine which activity takes precedence over another, i.e. which must happen before another can take place. These are, except in the simplest of cases, very difficult to construct by hand, unless the person is very experienced, and available software is of a great advantage. 

Taking the list of tasks given in the Gantt Chart for Product X the order of precedence can be drawn up. 

The complexity of the diagram rapidly increases when further tasks are added, particularly those that are carried out in parallel to the main activities. They can then be used for determining the critical path in a complex project.

The processors in a physical model can be modeled as objects, their states modeled as attributes, their capabilities modeled as attributes, and communication links shown as explicit objects. It is useful to make visual distinctions between categories using stereotypes or a distinguished notation such as the one UML provides or, you can use traditional network diagram symbols for the different hardware objects. Base operating systems can be shown as part of this hardware architecture (see Figure 12.1). 

Acronym for Critical Path Method. A network diagramming technique that places emphasis on time, cost, and the completion of events. 

Visualization of landscapes via network diagrams has also led to novel developments in the exploration of SAR data. Examples include the SALI networks described by Guha and Van Drie (38) and network similarity graphs (NSGs) described by Wawer et al. (40). Both network representations use compounds as nodes and draw edges between them based on a metric that characterizes the pair of nodes in the context of the landscape (SARI for NSGs and SALI for SALI networks). The networks can be then analyzed to identify specific SAR trends. For example, Wawer et al. (41) described an approach to identifying SAR pathways (paths in an...

The network diagram derived from these activities is shown in Figure D18. 

The critical path for a project is that which determines the shortest time in which a project can be completed. It is of greatest value where there are sophisticated network diagrams, involving multiple parallel activities. 

The method involves the addition of the earliest start and latest finish time for each activity on the network diagram. Then using the list of precedents it is possible to calculate the shortest time in which the project can be completed. 

The structure of a multiphase medium can be specified by the spatial distribution of the phases that form the medium. This spatial distribution can be generally represented by the phase function or, in specific situations, by the equivalent pore-network diagram, by the spatial distribution of particles or other constituents, and by the probability density function. Examples of the representation of the porous media are shown in Fig. 2.

These SOPs should clearly define the inpnts and expected outputs of the process covered in order to provide objective measnrement criteria to determine whether the process is being successfully operated or not. This state of control shonld then allow the required electronic records to be created and maintained by the system, in addition to the creation of any documentation specified as part of its reqnirements, as ontlined in the traceability requirements diagram shown in Figure 36.2. Any relevant snpporting process flows, system overview, or network diagram documentation should also be reviewed and revised as necessary to reflect the new bnsiness processes if the requirements and SOPs for the system are updated in the fnture. 

Network diagrams should identify all critical equipment, e.g., servers, routers and bridges, and should show coimections between LANs and WANs. 

A popular approach for team members to develop a project network diagram is a concept known as the yellow sticky method. This method uses post-it notes, roll-paper, and markers and the team to develop a network diagram. The suggested steps of the yellow sticky method are as follows ...
