The CEO First 100 Days — Diagnose, Don't Decree

Executive simulation set in the first 100 days of Lucia Arenas-Beltran, the new CEO of Helio Verde S.A. Under chair, board, and analyst pressure to decree a strategy, the participant must instead install diagnostic discipline. Across ten 10-day windows, allocate time across the six stakeholder claims (cabinet, skip-level, frontline, customers, board, external ecosystem), choose a defensible posture at each pressure event, and earn the autonomy of the operational phase by writing a disciplined 100-day memo to the chair. Anchored to Watkins, Gerstner, Mulally, Nadella, Lafley and Martin, and Bossidy and Charan.
