Finally I got a book ("Scrum The Art of doing twice the work in half the time" by Jeff Sutherland) from the library. It's fantastically easy to read and follow, it's really good for all of us, who spend hours, days and months working with software. Moreover, it's the book for bosses, who used take wrong decisions and mismanage projects. It's a book for all people, who wants to work effectively in times, when time and creativity values the most. The book is full of real examples, who can inspire all of us to work better. It's the book for future leaders, who wants to be on a top of companies and society professionally and socially. I really enjoy reading and can suggest to read.
