You can't believe how many people search for the terms "12-hour shift schedule examples" or "24/7 shift schedule examples." They apparently assume that any attractive schedule example will work. They also believe that they can "sell" their co-workers or upper management on this new schedule.

These are dangerous assumptions. In groups of less than 50 employees, work patterns you find searching the Internet won't necessarily be the best choice. That's because they are designed for 24/7 coverage using 4 crews. They also may have different overtime weeks. And pushing a single scheduling option is rarely going to gain widespread support or buy-in.

When I design schedules, creating the work pattern is the very LAST STEP in the process. I start by asking how the workload varies by hour of the day and by day of the week. Most organizations don't track this, but they can tell you the coverage requirements at different times of the day. Usually this is expressed in 8-hour blocks because the organization was using 8-hour shifts and they know the coverage needed on each shift. In many cases, this approximates but doesn't accurately match the work volumes.

Many smaller organizations have either a heavier or a lighter workload on weekends. Police departments and dispatch units are often busiest on Friday and Saturday, especially in the evenings or when the bars close. Other industries often have less work on the weekends and can reduce the coverage to just one or two people all day Saturday and Sunday.

Once you know the coverage requirements, you can determine whether the available resources are adequate. The resources are the staff size, absence rate, and average hours of work each week. I use a staffing calculator similar to the one on my website. You can access it here: http://www.shift-schedule-design.com/Staffing_Calculator.

Then I decide which shift lengths would best match the coverage requirements. In most cases, this is either 8-hour or 12-hour shifts. 10-hour shifts are only considered if the workload increases for 6, 12 or 16 hours a day. That's because the 10-hour shifts overlap for that many hours, depending on how you use them. For most 24/7 organizations, 10-hour shifts just have too many limitations.

The next step is to look at the preferred schedule format, i.e. fixed or rotating shifts. Although employees tend to prefer fixed shifts, they present several challenges for management. With 8-hour shifts, using fixed shifts also may require a few more employees.

The final step is to develop different work patterns. Sometimes, popular patterns such as the Panama, Pittman, DuPont, 4-on-2-off, 6-on-3-off, etc. can be used. Sometimes these patterns can be tweaked to fit the organization's overtime week. Sometimes a pattern must be created from scratch. The key point is that you should never start with a pattern. It will not ensure the most effective or efficient use of your staff. It can cause over-staffing. It can cause unnecessary overtime or sacrifice the maximum possible number of weekends off. It should always be the last step in the design process.

During this final step, other considerations may come into play. For example, the group may be able to build relief coverage or training time into the schedule. They may have a bargained requirements for no less than 2 consecutive days off. Or they may want a slow shift rotation. These often require custom-designed patterns.

One last point. I always encourage clients to choose from multiple options. This allows you to compare the pros and cons, and make the necessary tradeoffs. I also recommend that clients use a strategic schedule selection process, as described here: http://www.shift-schedule-design.com/Schedule_Selection_Process. This will lead to superior choices that are supported by a majority of the employees who must work the schedule plus managers who oversee the operation.
