In the same way that software is eating the world, software management is eating traditional company management. Software projects are getting more important, sometimes centrally important to the future viability to more and more companies that aren't traditionally software oriented. Software projects are moving up the stack so they touch every part of an organization.

Agile is being blamed for problems that are really organizational, company-wide issues that a software team has to deal with because they now are central to how everything runs. The author's suggest to read more general business/organizational management type books is apropos, because the overall goal is agility of the entire organization, not just the software team.
