The Perception of Productivity in Software Development

How do you define develope productuity? Well, that is the elusive question of the last three decades for everyone in engineering. The research you are refering to is of white paper that you have quartered titled, an actionable framework for understanding and improving developer experience. I believe that productivity is ultimately around how developers feel. People try rigt people try to count things like lines of code or poll request or tickets but anyone who's in softfor development knows these things don't capture the size nor complexity of work.
