Article 4.1.1. (a) shows the obligation what you need to do when you have accepted a Project or a Next-Action.
Any Circle Member can, at any time, ask you to provide insight on the Projects and Next-Actions that you have accepted. Then the relative priority comes to play. Each Member decides, based on the rules set in Article 4.1.3, how to energize his personal resources. Based on this the Member can give Projections (Art. 4.1.1.(c) on the open Projects or Next-Actions.
Hope this helps.
