So, I took my deck of task cards along to the last meeting and talked to the other producer and one of the project leads about what we want to get out of the schedule. We all acknowledged barely concealed hatred of the Gantt and they’d noticed the same flaws as me.
Classical “XP-style” card scheduling kind of avoids the calendar, which is the main reason the other producer likes the Gantt, they’re fond of seeing things against a representation of time. So we agreed that a big calendar plus the cards might give a better scheduling game than we have. We’ll see at the next group meeting in a week.
