'Tidy First?' by Kent Beck is a very quick read. I finished it in under three hours. Its 92 pages are only a bit more than half filled.

Part 1: Tidyings (~30 pages) is quick and easy and could tempt you to put the book down before finishing -- Don't.

Part 2: Managing (~20 pages) is also quick but not quite so easy. In this part the ? is brought to the fore.

Part 3: Theory (~35 pages) is quite profound and worth serious contemplation.

Disciplines, standards, and ethics are the three components of a profession. The three parts correspond well.

I look forward to book 2.
