The practical guide to defect prevention (developer best practices) [marc mcdonald, robert musson, ross smith] on amazoncom free shipping on qualifying offers this practical, hands-on guide captures, categorizes, and builds a process of best practices to help avoid creating defects during the development process—rather than fixing them after extensive analysis.
