Jim Shore's book is a very good book, but it is aimed at a different audience - it has great advice for developers, teams, and team leads. Leading Lean Software Development is aimed at organizational leaders. Books you might compare it to would be "Outside-in Software Development" by Carl Kessler and John Sweitzer, and "Freedom from Command and Control" by John Seddon.
