tldr version: Principles are like rules: you are either compliant or you are not. This gives rise to “bounded sets” of rule-followers and rule-enforcers rather than “centred sets” of people with shared values.2 Instead, I started thinking about properties: qualities or characteristics of code rather than rules to follow. Properties define a goal or centre to move towards. Your code is only closer to or further from the centre, and there is always a clear direction of travel. ..... and then he gives a list of five properties that good architectures can aim for.
