Question 9

Alexander Demetrius Dickson,ADD to his friends,has three big projects he is working on,and he can't seem to organize his time effectively.Each of the three projects,we'll call them A,B,and C,should take ten days to complete.He is currently contemplating two different approaches.Approach one is to work each project to completion before starting on the next.The problem with this approach is that he tends to burn out if he works on one task for an extended period of time.For every two days he works on one single task,he finds he must take a half day off.ADD's alternative is to multitask,that is,work on project A for a day,then switch to project B for a day,before switching to project C for a day.The problem with this approach is that there is a small setup time equaling one-quarter of a day associated with each transition.Use a Gantt chart to show the effect of each approach and determine which method is the best (has the overall fastest completion time)for performing this work.

Accepted Answer

The actual task time and idle time are i
