Traditional CIOs are often perceived as tactical managers, controllers, or order takers. But digital CIOs need to be the “constructive disruptors” to break down silos and break through conventional wisdom. The purpose of this book “The Change Agent CIO: The CIO’s Dynamic Role of Leading Digitalization“ is to share insight into the multifaceted CO leadership disciplines and multidimensional change agenda of IT. The digital CIOs are in demand to “disrupt,” inspire changes and accelerate digital transformation. They are change agents to reinvent IT as the business growth engine, optimize business processes and structures, rejuvenate the corporate culture and communication, and raise their intellectual voice to lead change interactively, innovatively, and relentlessly.
