When people say one programmer is more productive than another what they really mean is that the more productive programmer in general writes code with better structure. Part of that structure is following the conventions of the language and the community and so the code is easier to follow and reason about. But there is also another component of the structure that is harder to quantify and describe, the code in general is more “aesthetically” pleasing. Productive programmers somehow know when to break away from structure in order to accomplish the over-arching goal of making the entire code base easy to read and reason about. I don’t know how to acquire this quality because most studies of productivity, both professional and anecdotal, come down to either measuring lines of code or penis size.
