Please answer all 3 question with 200+ words each and references. Thank you

1. What are the strengths and weaknesses of using a Gantt chart for representing a project plan? How about a Network diagram and a PERT diagram? When they should be used ? Is one method "better" than the other? Should we combine them together?

2. Suppose that you are an analyst for the ABC Company, a large consulting firm with offices around the world.

The company wants to build a new knowledge management system that can identify and track the expertise of individual consultants anywhere in the world on the basis of their education and the various consulting projects on which they have worked. Assume that this is a new idea that has never before been attempted in ABC or elsewhere.

ABC has an international network, but the offices in each country may use somewhat different hardware and software. ABC management wants the system up and running within a year.

Question: What methodology would you recommend that ABC Company use? Why?

3. Think about your own university or college and choose an idea that could improve student satisfaction with the course enrollment process.

Currently, can students enroll for classes from anywhere? How long does it take? Are directions simple to follow? Is online help available?

Next, think about how technology can help support your idea. Would you need completely new technology? Can the current system be changed?

Question: Create a system request that you could give to the administration that explains the sponsor, business need, business requirements, and potential value of the project. Include any constraints or issues that should be considered.
