Businesses are not maximising their scientific and technical human capital and are therefore missing out on innovation and growth opportunities. Global risks are intensifying, threatening the wellbeing of our children and future generations. These risks are a result of years of irrational decision-making; the world urgently needs rational thinking and less gut feeling. Having scientific thinkers at the leadership table can turn the tide. This book hopes to inspire business and global leaders to focus on coaching Science, Technology, Engineering, Mathematics and Medicine (STEMM) professionals to become senior leaders within their organisations. It also seeks to empower STEMM professionals everywhere to pursue influential leadership roles and ensure they undertake leadership development programs that specifically cater to their needs. There is tremendous untapped power at the intersection of influential STEMM leadership and the transformation of organisations, and the world. Scientists in Every Boardroom presents the results of extensive research, coaching case studies and interviews on leadership development in the hope that solutions can be found to what seems to be a crisis in rational leadership. It is not about criticising past and current leaders; it is about providing new avenues of leadership that will ensure a better way forward for all organisations and for the future of our planet.
