Balancing Agility and Discipline

I'm finishing this book that I have started to read for my Msc. Thesis, but I haven't finished it, because I had a lot to do writing my Msc. Thesis.

The authors of this book are Barry Boehm and Richard Turner, the name of the Book is "Balancing Agility and Discipline: A Guide for the Perplexed".

There are six conclusions of this book [Boehm & Turner 2003, p. 148]:

1.- Neither agile nor plan-driven methods provide a silver bullet.
2.- Agile and plan-driven methods have some home grounds where one clearly dominate the other.
3.- Future trends are toward application developments that need both agility and discipline.
4.- Some balanced methods are emerging.
5.- It is better to build your method up than tailor down.
6.- Methods are important, but potential silver bullets are more likely to be found in areas dealing with people, values, communication, and expectations management.
