There is no end to the search for a developer productivity metric, but it refuses to be found for reasons that are fairly obvious to technical people, but that doesn't stop people from trying – for decades. So now they've retreated to these vectors called "frameworks" that try to obscure with complexity the fact that they are not in any way able to "measure what matters" – in this case, the ratio of value output to value input – nor are in any way deserving of the term "metric". I contend that such non-measures are of absolutely no value to engineering managers; they're management theater and purely a distraction and a waste of time.

Let's leave aside for a moment that this piece begins with an impressively uninformed and circular definition – "Developer productivity, in general, refers to how productive a developer is during a specific time or based on any criteria." – and focus instead on the question of why does this stuff keep popping into existence; what's behind it?

As a tech exec who's researched and given several talks on this to large audiences of non-technical execs like CEOs and CFOs, I believe the root causes are an understandable and intense desire for "visibility" and exec accountability coupled with a set of false beliefs held by non-technical managers including "anything can be measured if you try hard enough" and "nothing can be managed unless it's measured" and the classic quantitative fallacy of "things that can be measured are more important than things that can't be". Besides, it's only fair that if the VPs of sales and marketing have to stand up and talk about funnel metrics and sales rep productivity (with real metrics like net new bookings divided by fully loaded sales rep cost) that the VP of engineering - an often enormous fraction of a SaaS company's budget – should be similarly held to account for some number, any number, we just need a number, so we can look for "trends" (actually, noise). It also seems to be driven by a push from HR for fairness in promotions and terminations, which is also totally understandable, yet misguided.

I have a wisecrack response to non-technical executives when discussing this which is "how do you measure your own productivity?" that helps them understand the absurdity of what they're trying to do and how common it is that no true measure of productivity exists. People really struggle to understand that some metrics, no matter how great it would be to have them, simply do not exist, and so we have this – measurement theater.
