The Market Research Store has four orders on hand, and each must be processed in the sequential order:

First: Department A—computer analysis Second: Department B—report writing and printing The following table lists the number of days required by each job in each department. For example, job IV requires two days during computer analysis and one day in report writing and printing.

Job I Job II Job III Job IV Department A 3 6 5 2 Department B 8 3 4 1 Assume that no other work is being done by the departments and that “no passing’’ of jobs is allowed. Use a Gantt sequencing chart to show the best-work schedule. (Best-work schedule means minimum time to finish all four jobs.)
