CB.14:4.2 - Use differences to find a useful exchange

When participants want to learn from contrasting practice, agree which dimensions matter to their work. Select several that can reveal distinct strengths or limitations, such as recoverability of a case account, effort spent obtaining missing information and usefulness of the returned explanation. Explain what each observation means and use comparable cases where possible.

Invite participants to describe their own practice against those dimensions, with examples and relevant conditions. Keep unknown observations visible. A large gap is a reason to investigate what differs; it may arise from case mix, tools, access, experience or the way the observation was made.

Discuss a contrast with the practitioners who produced it. Ask how the apparent strength was achieved, which conditions it required, what it cost and where it failed. Look for reciprocal contributions: one group may have an effective intake conversation while another makes its later reasoning easier to recover.

Choose a specific exchange from that comparison. Name what one participant will show, what the other will try, and what result they will bring back. CB.15 supplies a connection with another practice when the needed experience is outside the current group. A learning programme for a particular person then uses HCD as needed.

Use a stable scale only when its meanings and progression fit a sufficiently stable practice. For a changing practice, describe the differences and test promising alternatives. Preserve dimensions separately unless a justified decision rule needs to combine them. The purpose here is to find useful work and partners; an overall league table would answer a different question and can make candid comparison harder.
