Great books and great methodology. It would be even better if the author didn’t oversell it. The way he presents it, is like he treated all diseases on the planet. After a while of such praising of his work you start to question his credibility.
The author made a good point. You can't significantly change the performance of a person in a short time. However you can significantly affect the team. Everything should be seen as a system. People are just the participants in the game.
There are no bad people, but bad systems
The book made me think of Nazism. Its success can be explained by the system that was in place. Most german people didn't want to kill anyone on the individual level. However they played their cog role in the complex Nazism machine.
Anyway, back to the book. Scrum is focused on providing the basic rules for the process in the team. It prioritises efficiency, uncertainty and change. I can't think how those rules could be distilled even more. That make me think the scrum would be around for a long time.
I would recommend this book to everybody. But don’t be put off by the writer. The product does not change because of the bad salesperson.
