First Printing and Copy Center has 4 jobs to be scheduled. Production scheduling personnel are reviewing the Gantt chart at the end of day
4.
Job
D
was scheduled to begin early on day
2
and take
7.5
days. As of now (the review point after day
4),
it is 2 days ahead of schedule.
Job
E
should begin on day
1
and take
4
days. It was on time.
Job
F
was to begin on day
2,
but maintenance forced a delay of
0.5
day.
The job should now take
5
full days. It is now on schedule.
Job
G
is a day behind schedule. It started at the beginning of day
2
and should require
7
days to complete.
Add the actual progress to the Gantt schedule shown on the right (on which the planned timings have been already plotted as blue lines).
Using the line drawing tool, plot the actual progress showing the actual start and the expected finish on top of (overlapping) the maroon dashed line provided just above the job number for each of the tasks.
