She is about to take delivery of six machines at a total cost of $4 million. These machines must be installed and fully tested in time to be used on a new production line scheduled to begin operation in 6 months. Because this project is important, the plant manager would like to devote as much time as possible to the job, but she is currently handling several other projects. She thinks she has three basic choices: (1) she can handle the project informally out of her office; (2) she can assign the project to a member of her staff; or (3) the company that manufactures the machines can handle the installation project for a fee close to what the installation would cost Maladroit. Questions A. Would you classify the work of installing the six machines as a project? B. Why or why not? C.

The company estimates that 150 hours will be required to complete the project. The firm's three graphics designers available for assignment to this project are Lisa, a senior designer and team leader; David, a senior designer; and Sarah, a junior designer. Because Lisa has worked on several projects for Lake View Winery, management speci fied that Lisa must be assigned at least 40% of the total number of hours assigned to the two senior designers. To provide label-designing experience for Sarah, Sarah must be assigned at least 15% of the total project time. However, the number of hours assigned to Sarah must not exceed 25% of the total number of hours assigned to the two senior designers. Due to other project commitments, Lisa has a maximum of 50 hours available to work on this project.Hourly wage rates are $30 for Lisa, $25 for David, and $18 for Sarah.a.

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…arrow_forward
