As the “Fourth Wave” of the industrial revolution progresses, the importance of leadership in a complex and turbulent world becomes ever more critical. Leadership by those trained and skilled in the world of technology is moving to the forefront. No longer can technologists merely create new products and services and then hope that others will develop and apply these innovations in constructive ways. Instead, engineers must expand their skill set to improve their ability to influence others. Tech Leadership 4.0 guides technical trailblazers into the Fourth Wave by emphasizing the importance of self-awareness, personal balance and organization. The authors, one an engineer and the other a psychologist, provide an in-depth and detailed prescriptive guide to developing the skills needed to be a successful Fourth Wave leader.
