So is there any more clarity on what this new roster system is going to deliver?
Not really. There's lots of verbiage about "preferences", and "bid groups", I'm fairly middling on my status list and would certainly like to see concrete examples of how one of my bids would be processed by "JSS" before coming to any conclusions. If anyone here has actually worked under JSS I'd be interested to hear their comments.
Overall it feels to me we're being asked to buy a new car without being allowed a test drive.
