(a) What is the total utilization? (b) Construct a preemptive EDF schedule for this system in the interval (0,18).Label any missed deadlines. In this and the next part, assume that each job that missesits deadline is still executed in its entirety. (c) Construct a preemptive RM schedule for this system in the interval (0,18).Label any missed deadlines. (d) Suppose we want to reduce the execution time of the task with period 3 to makethe task set schedulable (i.e., all deadlines are guaranteed to meet) with the preemptiveEDF algorithm. What is the minimum amount of reduction necessary?

The purpose of this question is to explore the concepts of team's velocity and project size. Consider three teams operating with the following velocities, Team (a) – 400 points per iteration Team (b) – 500 points per iteration Team ( c) – 900 points per iteration Each team operates with the following cadence, Team (a) – 2 weeks per iteration Team (b) – 5 weeks per iteration Team ( c) – 3 weeks per iteration We also have the system test team that needs to integrate and test the complete application and cannot test a part of it. Consider three projects with the following sizes in points, 3000, 6000, 9000. Question is which team should engage with which project? The goal is for all three teams to complete their respective projects at the same time, and hence to enable the system test to start verification without waiting for anyone? Team (a) should receive a project with 6000 points Team (b) should receive a project with 3000 points Team (c) should receive a project…
