Philippe's 3 Rules of Software Craftsmanship:

#1 "Start with a vision"
#2 "Throwing more bodies at software projects only makes things worse"
#3 "There are three vectors that drive software craftsmanship: quality, schedule, and features. The challenge is that you only get to pick two"

Side dish:
Phillippe's law : "The productivity of a software developer in a team of N people is diminished by dividing it by the cube root of N"
