- The Virginia Department of Transportation is undertaking a construction project to widen a large section of interstate highway near Wahington, DC. The project includes the construction of a number of new bridges, interchanges and overpasses. The first step in the process is to appoint a project manager and develop a project team, whose members will be departmental employees and private consultants and operatives. The team for a project of this size also requires a large support staff with a variety of technical skills. Once the team is selected and the staff is in place, the next task is to select a primary contractor to manage and oversee the construction.

During this time Brian will figure out how to design the network. Brian estimates that screening and hiring a contractor will take about one week and that the network design will take about two weeks. The new center requires a new ventilation system. The manufacturer's requirements include an ambient temperature of 67 degrees to keep all of the data servers running at optimal speeds. The ventilation system has a lead time of three weeks. Brian will also need to order new racks to hold the servers, switches, and other network devices. The racks have a two-week delivery time.

- Recently, you were assigned to manage a project to remodelthe seminar room for your company. You have constructed anetwork diagram depicting the various activities in the project(Figure 7.13). In addition, you have asked your team to estimatethe amount of time that they would expect each of the activitiesto take. Their responses are shown in the following table: a. What is the expected completion time of the project?b. What is the probability of completing the project in 21 days?c. What is the probability of completing the project in 17 days?A project has three tasks and three members. These tasks include preparing a bill of materials task and preparing an estimated task must be the project team's responsibility, while the project manager is considered accountable for these tasks. For the Preparing estimate task, the sponsor must be informed. The third task, sending procurement documents task is the responsibility of the project manager, while the project team is accountable for this task, in the other hand the sponsor indeed must be informed of this task. Decide what is the suitable chart type that can be used to list the above tasks and mapped to everyone involved in the project using samples (R, A, C, I). Elaborate your answer by providing the full meaning of those samples and create the table that represents the relationship between these tasks and the samples.Dave Fletcher was able to determine the activity times for constructing his laser scanning machine.

- 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.

- Mangement Project management is a discipline that involves planning, organizing, and overseeing the execution of a project from initiation to completion. It encompasses defining project goals, outlining tasks, allocating resources, and managing budgets and timelines. A successful project manager must possess strong leadership skills, effective communication, and the ability to mitigate risks and solve problems efficiently. Collaboration among team members is crucial, as is the flexibility to adapt to unexpected challenges that may arise during the project lifecycle. Continuous monitoring and evaluation ensure that the project stays on track, meeting objectives and delivering value to stakeholders.
