Dear Students,
Below is something I pulled in from WikiAnswers:
The network diagram display logical relationships among the various activities that take place within a project.
It also allows the project manager to see how the various activities flow towards to completion of the project in a sequential manner.
It provides an overview as to how resources are utilized in a project for a given time period which could help the manager to perform resource leveling if necessary.
As you can see, there is much information that you can pull from the Internet. However, please take caution not to do cut-and-paste. Your examiner in UK also has the software tools to identify cut-and-paste statements. The last thing your report need is to be marked as a 'plagiarized' work. Use the information you get from the Internet to help you interpret and write your own answer to the question.
As highlighted in last lecture, 'explain' and 'discuss' are two different things. As Q.6. carries 10 marks, I would say the proportioning would be 4~5 marks for explaining and 5~6 marks for discussion.
'Explain' refers to stating the facts on what is the purpose of network diagram. This is quite direct and you should be able to get from most books and/or the Internet.
'Discuss' is more tricky as your understanding and critical thinking on the subejct is required. You may need to compare the use of network diagram with other methodologies (say, Gantt Chart, refer to my Lecture 2 slides) in project management; the pros and cons; how prevalent is it use in modern project management etc.
Here's a thought that just came into my mind - why is it that most people actually use more of Gantt Chart in planning and scheduling of projects, but not network diagram. I am sure even in your working environment, you would have seen Gantt Chart before but not network diagram. Why?
