documentation & UML

customer care about software

code is documentation

people are the documentation

documentation was also time to think about design

documentation depreciates, while the software becomes complex

team organization

developer huddle show cases

Conway's law

organizations which design systems are constrained to produce designs which are copies of the their communication

design individually review together

design together review individually
