Image of Diagram included Using the diagram, find: The critical path. How long it will take to complete the project? How does simulation determine the probabilities of various project completion times? What is "slack" and why is it important? Why is activity-on-arrow (AOA) or activity-on-node (AON) of significant value to the project manager? How is the uncertainty in project scheduling dealt with? Should the critical path activities be managed differently from noncritical path activities? Explain.

Entrepreneur Andrew Field bought a print shop and used his selling skills to boost sales to about $1 million annually. The high fixed cost structure of his business resulted in only a break-even situation, however, and Field saw no hope for improvement given his relatively small local markets. The idea for a Web site finally struck. Field devised an interactive Web site system to fill his idle capacity. Customers design and submit their orders through a simple program. The company then e-mails a project number and link to a proof of the order, and once approved by the customer, a production, shipping, and delivery date are established. Field filled his idle capacity and then took his company to the next level by soliciting more work and subcontracting that to competitor companies. Word of the ease and reliability of Fields system has spread, and the company now averages about 7,000 visitors to its site each day, generating sales of $8 to $9 million. Q1. Would Fields strategy for…
