Management & Science University (MSU) have appointed you as a project manager to conduct a Joint Application Design (JAD) session with members from various departments. As a project manager, you are required to develop a specific schedule for the tasks listed below. The estimated task duration for each shown in parentheses. First, you must contact and brief the participants and explain their responsibilities (1 day). Then you must obtain approval from their department managers (3 days). After you have obtained the approval, you can begin the two tasks where you can prepare the agenda for the JAD session (7 days) and arrange the meeting room (2 days) When the agenda is ready, you can start two more concurrent tasks which are preparing the information packets (4 days) and to create visual aids (8 days). When the meeting room is arranged and information packets are ready, you can send out an email to all participants (1 day). Finally, after the e-mail is sent to participants and the…
