When organization search for a new shift schedule, they often cite one of these two goals: better work-life balance, or better staff utilization. However, when the workload varies by time of day or by day of week, that can require matching the coverage with the actual workload. In addition, if the workload or available resources often change, that means having a high level of flexibility so you can replace missing resources fast or adjusting the overall no of paid hours to keep the COGS level low. We also know that, current legal rules are difficult to meet, especially when operations require a high level of flexibility. Therefore, a smart schedule should always be considered an ongoing process.
