The next setting is 'Prevent employees from starting a task if there is work in progress.' You don't have to make a decision about whether this setting should be enabled or disabled at this stage. It works as follows: When it's turned off, an employee can start a task, scan a QR code in a zone, not finish it (which sometimes happens), and go to do another task in a different zone. However, if you enable this setting, the employee won't be able to start another task until they finish the current one.
