Johann Diaz

Johann Diaz is a service transformation leader with over 35 years’ experience helping organisations design change that actually sticks. His career spans frontline operations, global consulting, and enterprise-scale transformation roles across the public and private sectors in the UK and EMEA.

Johann works at the intersection of change management, service design, and operating model transformation, helping leaders move beyond fragmented initiatives toward coherent, service-centred organisations. In recent years, his focus has shifted to AI-enabled service transformation, where automation and intelligence are rapidly exposing long-standing weaknesses in service ownership, process design, and organisational structure.

As Founder of the Service Revolution Academy, Johann equips senior leaders and practitioners with practical frameworks to build organisations that can adapt continuously — without burning out their people or losing strategic control.
