So PERFECT for project schedules
I work in Purchasing, and I often have to schedule out the different steps within a bid process, and I also have to schedule the checkout of purchasing cards from my office. Color coding each task with a different color ink makes it easy to find the scheduled deadlines for individual tasks, and makes it easy to visually see the relationships between those tasks. Having magnets where I can attach necessary documents/emails and using color-coded magnets (to match my task ink colors) makes organization a breeze. AND since it's erasable, date changes don't require white-out tape, etc..
My only wish is that they had a floating month version that had movable week strips that could be shifted around as time progresses.
