Network diagram also do not clearly show time line for a project.
Large networks require dedicated maintenance and analysis.
Network diagram do not lead themselves to easy reproduction or distribution.
Tools and system can be expensive to acquire and maintain.
A dummy task is a task representing nothing (no actual work done), but is there only to clarify the activity network diagram. Source: http://www.pmhut.com/critical-path-mapping-with-activity-network-diagrams
Probably the best tool supporting product based planning technique (PRINCE2 technique) is P2ware Planner, http://www.p2ware.com. It supports * Product Breakdown Structure (PBS) * Product Flow Diagram (PFD) * automatic generation of PFD based on PBS * all changes are reflected on other diagrams (Gantt chart, network diagram) See related links.

The activity network in project management is significant because it helps visualize and organize the sequence of tasks needed to complete a project. It allows project managers to identify dependencies, allocate resources efficiently, and track progress effectively. By using the activity network, project managers can better plan, schedule, and manage projects to ensure they are completed on time and within budget.
The activity on node network in project management methodologies is a visual representation of project tasks and their dependencies. It helps project managers plan, schedule, and track progress by showing the sequence of activities and their relationships. This network allows for better coordination and resource allocation, leading to more efficient project execution.

disadvantages of using network
The importance of network analysis in project valluation are that (1)it allowes planning and co-ordination of resourses(2)it reduces and eliminate project idleness(3)it also reduces waste by efficient planning and co-ordination of resources.However it have got some disadvantages that (1)the time period taken by an activity is subjective as it is based on assamptions(2)it is also time consuming and complex to prepare network analysis
Go to google.com and put in network diagram, then click on images. You'll see more network diagrams than you counted on!
What are the disadvantages of having a network in an office?
Spread sheets, network diagrams
You will find computer network diagrams on Google images via the images tab. Wikipedia, gliffy, and compnetworking also have pages dedicated to computer network diagrams.
The disadvantages of a tree network are that it requires alot of cable to network and that if the central hub fails then the entire network fails. Also, it is not a prudent expense for a small network.
what is the dis advantage of MAN NETWORK
What were the disadvantage of the pre 1996 network
disadvantages: 1. implenentation cost is high. 2. not ideal for temporary network setup 3. not flexible.
network is based on which topology?
