Scrum - the secret weapon of the most successful modern companies. Google, Facebook, Amazon and Apple use Scrum to rapidly drive innovation, focus extremely accurately on customers, reduce decision-making time several times and get better and better. In the past few years, Scrum has gone far beyond the technology companies that spawned it and began to conquer the corporate world. "Scrum in practice" is the result of many years of experience working with several dozen companies. The purpose of this book is to better acquaint leaders, managers and employees with the specifics of the transition of companies to Agile, the difficulties they face during this period, as well as the opportunities that open up new ways of interacting in teams.
