When we were designing our planning software, we discovered a few things:
1: Everyone can read a GANTT chart, but they still allow a lot of information.
2: Most planners usually already know what needs to be done when someone calls in sick, and software should make this easy to do.
3: is that planning, even though it's complicated, in general repeats itself with a pattern throughout the year.
We built our software accordingly, which you can read more about in detail below.
