The case study explores the second phase of ABB’s 2018 to 2024 transformation journey to restore confidence in the underperforming conglomerate through a simplification of its structure and a focus on accelerating decision making. Under interim CEO Peter Voser and later Björn Rosengren (2020–2024), ABB decentralized operations, optimized headcount, enhanced accountability and empowered divisions to operate as independent businesses. Rosengren formalized the transformation as The ABB Way. On 1 August 2024, Morten Wierod assumed the role of CEO, inheriting a stronger, more agile ABB. To maintain momentum, the company needs to remain committed to operational excellence, relentless innovation and a strong customer focus. Moving forward, Wierod’s key challenges include identifying strategies to build on the transformation’s success.
