On 30 October 2024, the IBER-Kotosaka B2 (English-track) seminar reconvened with Nissan Motor Corporation for a second joint session, one year on from the October 2023 collaboration. As before, the MBA students of Hitotsubashi ICS joined as third partners. The brief this time was a different strategic topic, and — drawing on the trust that had built up over the previous year — we let Nissan's managers walk the room through the directions they had been refining in-house before the student teams presented. B2 and ICS students had each spent one to two weeks on the same question and arrived with their own, independently built proposals. Over several hours, the conversation drew on Nissan's internal framing, B2's undergraduate reframing, and ICS's operational reading of the same problem.

Building on last year

B2 joint sessions are always two-way: each one is designed as a live exchange between the student teams who have prepared on the brief and the executives who own the question. For this second Nissan edition, with the trust from 2023 already in place, we could be more flexible about sequencing. Nissan's internal team opened by putting their current framing on the table, and the student proposals then came in to extend and refine that framing rather than to start from a blank page. One to two weeks of independent prep on the student side meant the room had plenty of content from every direction well before the main discussion began.

Where the conversation went

Students tend to ask foundational "why is the problem framed this way at all?" questions that experienced practitioners, over time, stop articulating out loud. Applied to Nissan's internal framing, that kind of questioning was exactly what the discussion needed. As Nissan's managers worked through the students' questions, their own logic tightened. Over several hours, what emerged was a recommendation on Nissan's future direction that drew on all three perspectives — the student reframing, the MBA operational check, and the practitioner view all shaping the same conclusion.
