The Dimensional Interview

When a conflict is reported, the first step is not mediation. The first step is diagnosis. The dimensional interview is a structured conversation with each party individually — designed to identify the behavioral dimensions in collision, the specific trigger points, and the escalation history. You cannot resolve a conflict you have not diagnosed, and you cannot diagnose a conflict by listening to complaints. Complaints describe symptoms. The dimensional interview finds the cause.

1. Question 1: The Trigger "Describe the most recent incident. What exactly happened?" Listen for the behavioral dimension in the trigger. "They made a decision without consulting me" — D collision or S stability disruption. "They questioned my analysis in front of the team" — C evidence challenge or I social threat. The trigger reveals which dimension is activated.
2. Question 2: The Pattern "Has this happened before? How often?" A recurring pattern confirms a dimensional collision. A one-time event may be situational. If the pattern matches the profile collision prediction — two high-D individuals repeatedly fighting over decision authority — you have a confirmed dimensional conflict.
3. Question 3: The Attribution "Why do you think they do this?" Listen for attribution errors. "They are controlling" usually means high-D behavior threatening the interviewee's autonomy. "They are obsessive" usually means high-C behavior frustrating the interviewee's pace. The attribution tells you how the interviewee is interpreting the dimensional collision — and where the reframing needs to happen.
4. Question 4: The Accommodation "What would make this workable?" The answer reveals the interviewee's profile needs. "Give me advance warning" — S need for predictability. "Show me the evidence" — C need for validation. "Let me make the final call" — D need for authority. The accommodation request is the design input for the structural solution.
