Power Shift — The Newly Powerful Manager

A four-round executive-education simulation set inside Meridian Iberia Consulting, S.L., a Barcelona management-and-technology consultancy. On 2 June 2026 you are Álvaro Mendes, just promoted to Head of the Digital Transformation practice (38 consultants, €21,000,000 in annual fees) over Núria Camps — a nine-year senior manager widely expected to get the role, now reassigned as your direct report.

The whole firm watches power transitions on a public engagement-marketplace dashboard, so every overconfident, unilateral move is visible.

You start with a trust index of 62/100 and six working days to (1) diagnose the power transition and name the overconfidence traps that gaining power invites, (2) allocate the €4,200,000 Grupo Camino flagship mandate and choose the public framing and the private sequencing toward Núria, (3) calibrate a public Q3 forecast against an 80% band of €4,400,000–€5,900,000, separating appearing confident from being calibrated, and (4) recover trust and retain Núria — who holds three of the top-five accounts and €9,500,000 in at-risk fees — after a leaked Slack thread and a competitor approach.

Built on Sebastien Brion's (IESE) research on power and the loss of trust, the math models influence as a finite credibility budget: unilateral, self-aggrandizing, and badly-sequenced moves spend trust, while consultation, accurate credit attribution, calibrated commitment and kept promises replenish it.

The overconfidence gap (committed forecast minus calibrated expected value) is scored against a realized Q3 outcome, and ignoring Núria's exit risk can collapse the forecast entirely. Final KPIs track Trust Index, Account Risk, the Overconfidence Gap, and Influence Retained.

An advanced simulation for participants used to working with the main frameworks and trade-offs of the subject, designed for executive education and experienced professionals.
