Textbook Question
Chapter 13, Problem 8P
The professor from problem 6 is considering reducing the time for completion of the project. He can hire a teaching assistant (TA) to help with the new course, but this will cost additional money. The TA can help reduce the times only for activities A. D, and C. In each case the TA can reduce the time required by one day for $150 and two days for $300.
- a. Which activity should the TA perform to reduce the project completion time by one day?
- b. Can the network be crashed by two days in total? Explain why or why not?

Hoosier Burger Juan Rodriquez has assigned you the task of requirements determination for the Hoosier Burger project. You are looking forward to this opportunity because it will allow you to meet and interact with Hoosier Burger employees. Besides interviewing Bob and Thelma Mellankamp, you decide to collect information from Hoosier Burger’s waiters, cooks, and customers. Mr. Rodriquez suggests that you formally interview Bob and Thelma Mellankamp and perhaps observe them performing their daily management tasks. You decide that the best way to collect requirements from the waiters and cooks is to interview and observe them. You realize that discussing the order-taking process with Hoosier Burger employees and then observing them in action will provide you with a better idea of where potential system improvements can be made. You also decide to prepare a questionnaire to distribute to Hoosier Burger customers. Because Hoosier Burger has a large customer base, it would be impossible to…
