In my last post, I recommended using the following criteria to ensure a comprehensive approach to the schedule selection process: (1) effectiveness, (2) efficiency, (3) sleep, and (4) employee satisfaction. This post will cover the first criterion - effectiveness.
Effectiveness indicates how well a schedule satisfies the business needs. For most organizations, the primary concern is adequate coverage. Secondary issues include absence coverage, training time, cleaning and maintenance time, shift changes, equipment start-ups and shut-downs, and others. The following questions should help in the evaluation of schedule effectiveness:
- Do the coverage requirements match the workload by hour of the day? By day of the week?
-
Does the coverage meet or exceed the minimum requirements?
-
Is the coverage consistent?
-
How well are the organization's other business issues addressed?
Let's look at an example. A police department needs at least 2 officers working at all times. The department also has two busy periods each day in which it needs 4 officers on duty: (1) evenings from 4 p.m. to 9 p.m. and (2) from Midnight to 4 a.m. when the bars close. It also wants the 4 sergeants to work with the same crews at all times, and it wants rotating shifts. Here are three options they are considering:
- Option #1: 8-hour rotating shifts. This option uses 12 officers working an average of 42 hours a week to provide 3-person coverage on a 24/7 basis. This steady coverage does not address the two busy periods, so it falls short on this important consideration. The schedule uses 4 crews which would allow the sergeants to work with the same officers at all times.
-
Option #2: 10-hour rotating shifts. This option uses 15 officers working an average of 42 hours a week on two separate 10-hour schedules. Each schedule would align its overlapping shifts with one of the busy periods. This will provide 3-person coverage around the clock, plus 4 and 5-person coverage during the two busy periods. Unfortunately, these schedules do not use crews, so the sergeants would not be working with the same officers at all times.

Option #3: 12-hour rotating shifts. This option uses 12 officers working an average of 42 hours a week. The shifts would start at 4 a.m. and 4 p.m. to match the two busy periods. Coverage on the night shift would be 4 people. Coverage on the day shift would be 2 people. The schedule uses 6 crews. This means two crews would not have a sergeant.
