Why? If it’s unimportant to release this change early, why can’t people just wait before they turn the crank if they don’t care about it? Organizations with short lead times are free to wait until just before the change; organizations with longer lead times or additional requirements will have the data in order to deliver it when they need to.

Looking at it from a different perspective, what are the criteria for when to make a release and when not to?
