Openness to feedback is one of the essentials in sociocracy. For that reason, it is incorporated in many ways in sociocracy: meeting evaluations, role improvement, policy evaluations are some of the examples. Feedback between individuals, formal and informal, is another way of incorporating feedback.
Feedback is valuable data: it tells us both what is working effectively but also what needs adjustment. Shifting from a frame of criticism to a frame of constructiveness and curiosity puts us into a position where we can learn from each other and from the data we observe or measure. It adds the dimension of time: over time, we can evolve and self-repair, if we pay attention to feedback.
