Johnson's rule minimizes the total completion time of a set of jobs by scheduling them in the order that minimizes the maximum completion time. Since this particular job has a longer processing time in the painting department, it would be best to schedule it as late as possible in the unfilled job sequence to minimize its impact on other jobs in the system. This way, it would spend less time in the painting department, and the job that follows it would be able to start sooner.
