Accountability requires the accountable to acknowledge their commitments and the requestor keep track.
One cannot follow up on a commitment they don’t practively recall receiving, and one cannot well-execute on things one isn’t tracking to do. High performance teams are disciplined about both sides of this equation. When things are tracked well, any commitments that need renegotiation can be, while untracked commitments will disappoint as they slip. Action items help with this. Follow up on delegated/agreed tasks.rA1
