It has long been recognised that the technology industry is not diverse and gender inclusive. In the UK, the proportion of women in technology roles has remained stubbornly beneath 20% for the last twenty years. With this book we hope to help address that. This guide to tackling the gender imbalance in technology professions offers expertise, initiatives and true stories to support those wishing to bring greater gender diversity into the workplace. It aims to inform regarding background, theory and policy, advise on concrete actions that can be undertaken, and to be an exemplar for companies, organisations, establishments and campaigns in the form of real-world case studies.
