Answer 2

Johnson's rule is mainly used in two work centers for effectively organizing the jobs.

• The established law of Johnson accurately represents an observational system of organizing jobs in two principal centers of employment.  
• Its key aim is to properly recognize an optimum sequence of specific jobs to minimize the make-up to adequately reduce the completion time for various jobs.
• In Johnson's specific rule, the idle time on complex machinery is sufficiently reduced. It also reduces the flow time from the start of the first job to the end of the previous job.
