Yes, they’re all different ways of referring to the same thing. In designing LeaveBooker it is important to include all of them to cater for people using different terminology to describe our service. Describing LeaveBooker as an employee vacation planner is a good way to cover people who see a vacation tracking tool as something for planning time rather than seeing who is where.
These other people may try to find LeaveBooker by referring to it as a Time Off Tracker or Time Off Tracking application. So we need to address the different terminology people use to describe vacation/holiday/leave/time off as well as how they would name the tool — a planner, a tracker or a scheduler. Or even a booker of course!
So a totally different way of referring to it is “Vacation Scheduling Software“. In this case we have the addition of the term ’software’ which once again has its own set of synonyms — application/website/program and so on.
When you are looking for an application like LeaveBooker, you might also think purely in terms of what kind of absence you want to track. So it could be that you want to track sick leave (attendance tracking) or all types of leave. And are you looking for a solution that is going to be the sole time off tracking application, or are you looking at LeaveBooker purely to provide convenience to your staff, so they can book leave in an easy-to-use, web-based system?
These are some of the main challenges in explaining what LeaveBooker does, trying not to undersell it but still trying to be consistent in terminology usage!!!
