What most people think of as a Roster is really only a Timetable. It is why so many people invest endless hours of processing, juggling, and double-checking everything to ‘run the roster’ to make sure the timetable is right.
Many people who manage the roster to build the timetable have ended up with the responsibility for everything from compliance, to finance, to human resource management and don’t have the right tools to help them do it. It has been a very slow unintentional migration of responsibility in an environment of increased pressure and competition for resources that has for one reason or another not been recognised.
